The period ending June 30, 1984 saw the further implementation of the NOAO under the reorganization plan with the formation of the Engineering and_ Technical Services Division, the Public Information Office, and the Office of University Relations. The only remaining components to be implemented are Central Computer Services, scheduled for formation on 10/1/84, and the Program Management Office which is scheduled to be formed in the spring of 1985. This quarterly report is the first report filed by NOAO in the new consolidated format. II. SCIENTIFIC HIGHLIGHTS

A. Quasars have Close Companion Galaxies with the same Redshift Quasars have redshifts which, if interpreted conventionally by the redshift- distance relation, imply that these objects are at huge distances and so have enormous outputs of energy. Not all astronomers have accepted this cosmological interpretation of the redshifts and there has been a continual controversy as to their true nature. Generally, astronomers have sought to establish the distance of a quasar by associating it with other galaxies whose distances can be assigned with less contention. This approach was used by A.N. Stockton in 1978 with persuasive results; a new more broadly based demonstration that these quasar redshifts are indeed cosmological has recently been made by T.M. Heckman and E.P. Smith (University of Maryland), and B. Balick (University of Washington) using the 4-meter Mayall telescope at Kitt Peak. Heckman, etal., selected 15 quasars with redshifts in the range 0.05 to 0.41 and picked out galaxies which lay very close in the sky to each quasar. They got spectra of both the quasar and the nearby (some of which were as faint as 21st visual magnitude) with the Cryogenic Camera (which uses a CCD detector) at the Mayall telescope; the work covered the years 1981, 1982, and 1983. In 18 cases out of 19, the galaxy had the same redshift as the quasar. Neglecting the galaxies whose spectra showed emission lines and whose nature might be arguable, there were 14 out of 15 cases where the redshift of the quasar was the same as that of a normal galaxy which was separated from it by 50 kiloparsecs or less. Turning to previously obtained data on the redshifts of galaxies near quasars, Heckman etal. found that on the average, only 40% of the galaxies had shown the same redshift as the quasar compared with the 86% of their close-in sample of galaxies. They found only low relative velocities between the companion galaxies and the quasars, and this supports the other evidence that quasars are rarely found in rich clusters of galaxies where the velocity dispersion would be higher. They believe that their data support the hypothesis that galaxy interactions are an important means of triggering quasar activity. The close companion galaxies observed in this study did not themselves show strong nuclear activity or abnormal amounts of formation; this is in accord with what is known about the nuclear stimulation in nearby pairs of galaxies which is generally found to be rather modest. This is all strong evidence for a cosmological interpretation of quasar redshifts. Heckman et al. say, "In view of the direct and general nature of the evidence presented herein, apostles of the non-cosmological interpretation of quasar redshifts must now either recant, or else maintain that the unknown laws of physics which fix the redshifts of the emitting material in quasars extend to apparently normal galaxies located at appreciable distances from the site of the quasar pheonomenon itself."

B. Radio Galaxies with Record Redshifts Radio galaxies, although they are powerful radio-emitters, are comparatively faint compared with quasars at optical wavelengths. For many years, therefore, it was only possible to make optical identifications and get optical spectra of the nearer and brighter of these objects—those with the lowest redshifts. Catalogs of radio sources such as the 3CR (The Revised 3rd Cambridge Catalogue) then contained significant numbers of radio sources for which no optical counterparts were known. These "empty fields" were thought to be cases where the radio galaxies were too faint to show up on the existing optical survey material. Highly redshifted radio galaxies have relatively red optical images; consequently, the identification problem was improved when red-sensitive CCD detectors allowed deep red exposures to be made of these "empty fields." A detection is only certain when a confirming spectrum has been taken, and this is a very demanding task with these ^ery faint objects. The Cryogenic Camera on the Kitt Peak 4-meter Mayall telescope has proved extraordinarily powerful for this type of spectroscopy, since it can be used to get emission-line redshifts of galaxies as faint as 22nd visual magnitude in as little as a one-hour exposure; the faintest galaxies for which spectra have been obtained so far are in the range V = 23-24.

H. Spinrad and S. Djorgojorgovski (University of California, Berkeley) have been the most active users-s of this Kitt Peak equipment for identifying faint radio galaxies. In their latest survey with the Cryogenic Camera, they report the firm identificationidentificati of two faint radio galaxies (3C 13 and 3C 255), and a spectroscopic survey of 13 faint 3CR galaxies. Emission-line redshifts are now known up to z = 1.82 (3C 256), and new spectral data are available for 12 galaxies with z > 0.77; about half these show low-ionization emission-line spectra. The great strength of the [0II]3727 line (a characteristic of low-ionization emission) is of assistance in getting redshifts for these objects; it is also of considerable intrinsic interest. The radiation that excites these emission lines is much "softer" (i.e., weaker in the ultraviolet) than that which produces emission lines in quasars and Seyfert galaxies. The lines in these galaxies are relatively narrow (full width at half maximum less than 1000 km s_1), but they are often quite extended and inclined, or show structure. This suggests that interesting kinematic effects may be present in these, the most distant non-quasar galaxies that are known. It is to be expected that objects such as these will allow the extension of cosmological and galaxy evolution tests into previously unprobed territory. C. Magnetically Controlled Flow Patterns in the Solar Chromosphere Flows in the solar chromosphere above active regions are dominated by magnetic -• - indication of the magnetic field topology. These

cases is B. Lites (NOAO), S. Keil (AFGL), G. Sharmer (Stockholm), and A. Wyller (Royal Swedish Academy of Sciences) have recently observed these steady chromospheric flows in the optically thin He I 10830A line. Using a 100 x 100 element diode array with the echelle spectrograph at the Tower Telescope on Sacramento Peak, they observed the helium line, along with a nearby Si I line, in several active regions--a telluric water-vapor line was used as a wavelength reference. These observations demonstrate that the general association of photospheric magnetic field structure and transition region flows hold at the heights in the chromosphere where the He I 10830A 1ine is formed. This work demonstrated the possibility of making routine measurements of chromospheric flow patterns and active region dynamics with high spatial resolution. It will lead to further studies of the mass and energy flows in active regions. D. Optical Data Shows Some IRAS Sources to be Identified with Distant Galaxies The successes of the Infrared Astronomical Satellite (IRAS) are by now well known. Its discoveries of cool material surrounding nearby and a dust ring around the solar system captured public attention. During its short lifetime it made enough observations to yield a catalog of over 200,000 sources, a data base that will understandably lead to further important discoveries. Many of these results will come only after follow-up observations are made with ground-based telescopes at either optical or infrared wavelengths. Recent work by M. Aaronson (University of Arizona) and E. Olszewski (Dominion Astrophysical Observatory) appearing in Nature (vol. 309, p. 414) is a good example,

The observations showed that in four of the five cases, faint galaxies coincided with the IRAS positions. In the fifth case, reconsideration of the data indicated that the infrared emission could be extended and associated with a hot spot in the infrared-emitting clouds that IRAS found at high galactic latitude, therefore the source was probably of a different type than the others. Because the probability of unassociated galaxies falling by chance near the IRAS positions was low, they concluded that their identifications were correct and that distant galaxies probably account for most of the unidentified point sources found by Houck et al. Although the mechanism or process which produces the enormous amount of infrared emission is not yet known, one possible source is the occurrence of very active bursts of star formation surrounded by dust. An alternate source of the emission could be an active galactic nucleus that is heavily obscured by dust. More spectroscopic and radio observations are needed to decide if either of these explanations is correct. III. PERSONNEL

A. Advanced Development Program This was the first full quarter that the Advanced Development Program (ADP) was operating as a distinct unit of NOAO. The NNTT continues to be the first priority project for NOAO and as such, for the ADP. In addition to continuing work on the NNTT (see below for more detail), the ADP Division began work on the Infrared Adaptive Optics Program which is now in its definition stage. Different methods of sensing the atmospheric wavefront distortions using nearby sensor stars are being explored. We are defining the adaptive mirror which will be used to correct these wavefront distortions and expect to start procurement of that mirror in the next quarter. During the third quarter a major part of the general activities of the NNTT group focused on: (a) obtaining responses and suggestions from the astronomical community relative to the mounting concept and the project in general; and (b) summarizing and completing the information to be used by the Scientific Advisory Committee (SAC) in its decision-making process. Two meetings were held by the SAC--April 4-6: to prepare for the distribution of their "Preliminary Report" to the astronomical community; and June 14-15: a presentation in conjunction with the AAS meeting to allow the SAC to present its findings to, and ask for responses from, the astronomical community. In addition to the work required of the NNTT group to help the SAC prepare for these two meetings, progress was also made in the areas of: software update; examination of wide-field corrector designs; investigation of wind flow problems around large telescope enclosures; casting of honeycomb borosilicate mirror blanks — including the adaptation by the University of Arizona, Steward Observatory of their 2-meter casting furnace onto a rotation turntable on which a 30-inch blank was made with the spin-casting technique; designing the final details and assembling the hardware in the 1.8-meter mirror cell; installation of all major site testing equipment on both Mauna Kea and Mt. Graham; investigating ways to improve the durability of optical coatings and formation of a high quality off-axis parabolic surface on a 2-meter mirror blank, from which one could cut a hexagon measuring 1.8-meters across.

Cerro Tololo Inter-American Observatory Developments in the area of new instrumentation at CTIO for the third quarter included the installation of a new chopping secondary for infrared observations on the 4-meter; completion of a new declination drive for the Schmidt; construction of a direct coldbox for the large SIT vidicon detectors, and the first test of the new TV autoguider on the 1.5-meter telescope. The chopping secondary, which makes use of electronics provided by KPNO, was gold coated to reduce thermal emissivity, giving a 15% gain in throughput compared to the old secondary because of an improved optical design. The chopping axis can be rotated remotely and beam separation of up to 2 arcminutes can be achieved. The new declination drive for the Schmidt telescope eliminates the backlash problem of the old drive, permitting an autoguider to be used on the telescope. The direct coldbox for the large SIT vidicons allows them to be used either for direct imaging or on the long camera of the echelle spectrograph.spectrograph, Theine TViv autoguiderautoguiaer on thetrie 1.5-meteri. telescope, which is similar to the one used with the 4-meter prime focusfoe CCD camera, will make autoguidinc at the 1.5-meter possible for the first ti me, A DEC LSI 11/23+ computer system has been assembled and tested to allow use of software developed in Tucson on the CCD cameras at Cerro Tololo. Construction of an extension for the ETS lab was completed; the new storage tank for the La Serena fire station was installed; Tololo was connected to the MV/8000 computer in La Serena via the ENTEL microwave link. Chilean inflation was 4.1% during the quarter, which brings the total for the first six months of the calendar year to 6.6%. The exchange rate increased from 87.8 in January to 91.1 pesos per dollar in June.

C. Kitt Peak National Observatory Improvement projects for KPNO during this quarter included testing a new incremental encoder on the Mayall telescope declination axis; installation of collimation drives for the #1-0.9-meter f/7.5 and f/13.5 secondaries; installation and collimation of the #3-0.4-meter optics; and fabrication of modifications to the filter wheel mechanism for the #1-0.9-meter CCD optical/mechanical interface. The Varian computer system was removed from the 2.1-meter telescope; both the telescope and instrument now operate on the DEC PDP 11/44. The figuring of the mirror for the 2.1-meter chopping secondary was subcontracted. The hardware for the conversion of the #2-0.9-meter telescope to f/7.5 is nearly complete. Modifications to the building to implement a proper computer room plus a console room are in progress. The Texas Instruments (TI) 3-phase 800 x 800 CCD which was received via a NSF Astronomy Instrumentation Grant was installed in a Mark II Universal Dewar. The design of the Spectroscopic Event Counting System (SECS) camera head was completed. There were three seeing-studies observing runs during this quarter during which an attempt was made to demonstrate the effect of aperture size on seeing characteristics. The echelle intensified CCD system was installed and satisfactorily tested. Documentation on thehe IRAF system interface was completed and sent to theSTScIthe SI during this quarter.r. Work was continued on several IRAF packages including application to spectv"ncrnm'rctroscopic data reduction,rpHurt.inn. vacuum telescope data reductionreductic and analysis, and aran image display program.

D. National Solar Observatory A Global Oscillation Network Group (GONG) Workshop was sponsored by NS0 in Tucson on April 23-25, 1984 and attended by more than 40 interested scientists from around the world who gathered to discuss the objectives and requirements of a network of telescopes dedicated to observing the solar global oscillations. The Fourier Tachometer II was completed in the Sacramento Peak Big Dome. This instrument is designed to measure small Doppler velocities at eyery pixel in a two-dimensional image of all or part of the solar disc. Work is proceeding on a Correlation Tracker to stabilize image motion encountered during solar observations. The hardware for the new high resolution declination encoder on the HcMath has been fabricated; installation is scheduled for late July.

E. Central Offices

1. Director's Office During this quarter, the staffing in the Director's Office was completed with the hiring of Phyllis Williams as the Assistant to the Director. Efforts during this period were focused on the reorganization and preparation of documents such as the Program Plan, Long Range Plan, and Quarterly Report. The FY 1985 Program Plan was prepared and submitted to AURA for review.

2. Public Information Office Carl Posey joined the NOAO staff as Public Information Officer on June 1. The 1985 NOAO calendar project was completed and approved and, at the end of the reporting period, a contract let for production graphics.

3. Office of University Relations The Office of University Relations (OUR) began functioning on May 1, 1984 with David Crawford as the unit head. Because of its relative newness, efforts were concentrated on the AAS meeting in Baltimore and planning OUR goals for the upcoming year.

4. Engineering and Technical Services The major Research & Development (R&D) Program activities continued to be centered around the testing and evaluation of IR arrays. The testing of optical arrays has continued to be suspended until the open position for an engineer is filled. Construction of all of the optical and mechanical components of the Cincinatti Electronics InSb Array system has been completed. Fabrication of the electronics and assembly of the system are in progress. Preliminary tests are scheduled for late in the next quarter.

Three hours of observations were obtained in May at the 1.3-meter telescope during two nights of cloudy engineering time using the Hughes 58 x 62 Schottky Array. The results were presented at the Wyoming IR Detector Workshop later that month. The system has since been modified and a further engineering run scheduled for early July. A modified accumulation-mode CID was delivered by Aerojet General Corporation and installed in the laboratory dewar. The system was operated using the prototype CCD controller and the Varian computer system. Tests of the modified array showed a significant increase in noise, whose origin is being investigated. Personnel from the Santa Barbara Research Corporation visited the NOAO Tucson facilities in June for negotiations regarding the technical specifications of 58 x 62 element InSb arrays. The readout of these arrays will be identical to that of the Schottky Barrier device. Thus, equipment and techniques currently being developed will be directly applicable to these devices. It is now planned that four scientific grade devices will be purchased: two each for CTIO and KPNO to provide for an imaging and a spectroscopic system at both sites. Delivery is anticipated in the summer of 1985. A new GEC CCD has been delivered by Cambridge Imaging Electronics._ Test data provided by the vendor has shown this to be the best GEC device which we have seen. The horizontal charge transfer efficiency is low, but better than that of other GEC chips. For astronomical use, a "fat zero" of about 100 electrons would eliminate this problem with the result that the effective noise floor would be increased to about 14 electrons. The major activities for the Telescope Systems Program (TSP) during this quarter were related to shutdowns and maintenance and to the implementation of the Digital Equipment Corporation (DEC) computer systems on KPNO and infrared chopping secondary projects for the KPNO 2.1-meter and CTIO 4-meter telescopes. See Section C for details. The major activities during this quarter for the Instrument Systems Program (ISP) centered around the work on the FY 1984 instrumentation projects. See the division (ADP, CTIO, KPNO, NSO) entries for elaboration. The Coating Lab provided coatings on 42 surfaces for NOAO jobs.

5. Central Administrative Services Procedures were developed to document time and effort for all employees in compliance with 0MB Circular A-122, "Cost Principles for Nonprofit Organizations" to which NOAO will be subject on October 1, 1984. NOAO's liability insurance broker was changed from Snodgrass, Lovitt, Downey & Touche, Inc. to Johnson and Higgins of Arizona. The latter will perform a risk management study for AURA during the next three months._ The Accounting Manager met with various bank representatives to determine if NOAO would benefit from a change in financial institutions. Recommendations will be issued soon. An Addendum to the FY-1984 Program Plan reflecting implementation of "A Plan for the Formation of the National Optical Astronomy Observatories" was submitted to the NSF June 8, 1984. The FY-1985 Provisional Program Plan was submitted to the NSF June 29, 1984. The NOAO annual performance evaluations and salary review programs were initiated and the Executive Committee was provided justification for the FY-1985 salary increase pool for NOAO. Work was begun on "qualifying" AURA's retirement plan to allow for greater employee contributions.

10 The AOAF computer was expanded to include KPNO and NSO orders at virtually no cost to NOAO, resulting in increased efficiency in processing.
