Dow * Member of USNC-URSI Executive Committee iv DESCRIPTION OF INTERNATIONAL UNION OF RADIO SCIENCE The International Union of Radio Science is one of 18 world scientific unions organized under the International Council of Scientific Unions (!CSU). It is commonly designated as URS! (from its French name, Union Radio Scientifique Internationale). Its aims are (1) to promote the scientific study of radio co!IlIID.lnica­ tions, (2) to aid and organize radio research requiring cooperation on an international scale and to encourage the discussion and pub­ lication of the results, (3) to facilitate agreement upon common methods of measurement and the standardization of measuring instru­ ments, and (4) to sti11n.1late and to coordinate studies of the scien­ tific aspects of teleco!IlIID.lnications using electromagnetic waves, guided and unguided. The International Union itself is an organi­ zational framework to aid in promoting these objectives. The actual technical work is largely done by the National Committees in the various countries. The officers of the International Union are: President: Mr. J. Voge (France) Immediate Past President: Sir Granville Beynon (UK) Vice Presidents: Prof. W.N. Christiansen (Australia) Prof. W.E. Gordon (USA) Prof. V.V. Migulin (USSR) Prof. F.L.H.M. Stumpers (Netherlands) Secretary General: Dr. C.M. Minnis (Belgium) Honorary Presidents: B. Decaux (France) W. Dieminger (West Germany) J.A. Ratcliffe (UK) R.L. Smith-Rose (UK) The Secretary's office and the headquarters of the organiza- tion are located at Rue de Nieuwenhove, 81, B-1180 Brussels, Belgium. The Union is supported by contributions (dues) from 36 member coun­ tries. Additional funds for symposia and other scientific activities of the Union are provided by !CSU from contributions received for this purpose from UNESCO. The International Union, as of the XVIII General Assembly held in Lima, Peru, August 1975, has nine bodies called Commissions for centralizing studies in the principal technical fields. The names of the Commissions and the chairmen follow. V A. Electromagnetic Metrology Dr. H.M. Altschuler (USA) B. Fields and Waves Prof. J. van Bladel (Belgium) C. Signals and Systems Prof. B. Picinbono (France) D. Physical Electronics Prof; A. Smolinski (Poland) E. Interference Environment Dr. Ya. I. Likhter (USSR) F. Wave Phenomena in Nonionized Media Mr. F. Eklund (Sweden) G. Ionospheric Radio Dr. J.W. King (United Kingdom) H. Waves in Plasmas Dr. R. Gendrin (France) J. Radio Astronomy Prof. G. Westerhout (USA) Every three. years, the International Union holds a meeting called the General Assembly. The next General Assembly, the XIX, will be held in Helsinki, Finland in August, 1978. The Secretariat prepares and distributes the Proceedings of these General Assemblies. The International Union arranges international symposia on specific subjects pertaining to the work of one Commission or to several Com­ missions. The International Union also cooperates with other Unions in international symposia on subjects of joint interest. Radio is unique among the fields of scientific work in having a specific adaptability to large-scale international research programs, for many of the phenomena that must be studied are worldwide in extent and yet are in a measure subject to control by experimenters. Explora­ tion of space and the extension of scientific observations to the space environment is dependent on radio for its counnunication link and at the same time expands the scope of radio research. One of its branches, radio astronomy, involves cosmos-wide phenomena. URSI has in all this a distinct field of usefulness in furnishing a meeting ground for the numerous workers in the manifold aspects of radio research; its meet­ ings and counnittee activities furnish valuable means of promoting research through exchange of ideas. vi Steering Committee: G.

It is the only galaxy whose formation history can be stud- ied using the full distribution of stars from faint dwarfs to supergiants. The oldest components provide us with unique insight into how galaxies form and evolve over billions of years. The Galaxy is a luminous (L?) barred spiral with a central box/peanut bulge, a dominant disk, and a diffuse stellar halo.

Here we review the key integrated, structural and kinematic pa- rameters of the Galaxy, and point to uncertainties as well as directions for future progress. Galactic studies will continue to play a fundamen- tal role far into the future because there are measurements that can only be made in the near field and much of contemporary astrophysics depends on such observations. 529 Redshift (z) 20 10 5 2 1 0 1012 1011 ) ¯ 1010 M ( 9 r i 10 v 8 M 10 107 100 101 102 ) c p 1 k 10 ( r i v r 100 10-1 0.3 1 3 10 Time (Gyr) Figure 1 Left: The estimated growth of the Galaxy's virial mass (Mvir) and radius (rvir) from z = 20 to the present day, z = 0.

Westerhout 43 (W43) is a highly luminous galactic massive star-forming region at a distance of 5.5 kpc and the MM1 part hosts a particularly massive dense core (1000 M within 0.05 pc). We present new Herschel HIFI maps of the W43 MM1 region covering the main low-energy water lines at 557, 987, and 1113 GHz; 18 13 18 their H2 O counterparts; and other lines such as CO (10–9) and C O (9–8), which trace warm gas. These water lines are, with the exception of line wings, observed in absorption. Herschel SPIRE and JCMT 450 µm data have been used to make a model of the continuum emission at the HIFI wavelengths.

  • RADIO EMISSION from 16 POSSIBLE SUPERNOVA REMNANTS by D. K. MILNE* and E. R. HILL* 1. INTRODUCTION There Are Some 40 Radio Sourc
    RADIO EMISSION FROM 16 POSSIBLE SUPERNOVA REMNANTS By D. K. MILNE* and E. R. HILL* [Manuscript received August 29, 1968] Summary Sixteen radio sources, thought to be supernova remnants, have been observed at several frequencies between 408 and 2700 MHz. These data, together with previously published observations, have been used to derive spectra for these sources. The validity of the supernova remnant classification of certain of these sources is questioned. 1. INTRODUCTION There are some 40 radio sources classified in the literature as remnants of galactic supernovae. T:Q.e identification of these objects has generally followed the rules: (1) The radio spectrum is nonthermal. (2) The angular size is large enough to exclude identification as an external galaxy. (3) The object should be a population I member (i.e. within 250 pc of the galactic plane). (4) If the source is visible optically, then it should not be an HII region, and preferably should show some of the characteristic filamentary structure usually associated with supernova remnants. (5) A radio brightness distribution indicating a shell structure. To date the radio data available for these objects have been scant, particularly for certain of the southern sources. Within the range of the Parkes 210 ft radio telescope (declination +27° to -90°) there are 24 radio sources classified as galactic supernova remnants. Some of these have been examined using the Parkes facilities (e.g. Gardner and Milne 1965; Hill 1967 ; Whiteoak and Gardner 1967; Milne 1968a) whilst for the other remnants often the only data available are from the low-resolution galactic surveys (e.g.

  • The O-And B-Type Stellar Population in W3: Beyond the High-Density Layer
    Accepted to ApJ: 30 August 2015 A Preprint typeset using LTEX style emulateapj v. 08/22/09 THE O- AND B-TYPE STELLAR POPULATION IN W3: BEYOND THE HIGH-DENSITY LAYER Megan M. Kiminki1, Jinyoung Serena Kim1, Micaela B. Bagley1,2, William H. Sherry3,4, and George H. Rieke1 Accepted to ApJ: 30 August 2015 ABSTRACT We present the first results from our survey of the star-forming complex W3, combining V RI pho- tometry with multiobject spectroscopy to identify and characterize the high-mass stellar population across the region. With 79 new spectral classifications, we bring the total number of spectroscopically- confirmed O- and B-type stars in W3 to 105. We find that the high-mass slope of the mass function in W3 is consistent with a Salpeter IMF, and that the extinction toward the region is best characterized by an RV of approximately 3.6. B-type stars are found to be more widely dispersed across the W3 giant molecular cloud (GMC) than previously realized: they are not confined to the high-density layer (HDL) created by the expansion of the neighboring W4 H II region into the GMC. This broader B-type population suggests that star formation in W3 began spontaneously up to 8–10 Myr ago, although at a lower level than the more recent star formation episodes in the HDL. In addition, we describe a method of optimizing sky subtraction for fiber spectra in regions of strong and spatially-variable nebular emission. Subject headings: dust, extinction — open clusters and associations: individual (Westerhout 3) — stars: early-type — stars: formation — stars: luminosity function, mass function 1.

  • Star Formation and Molecular Clouds Towards the Galactic Anti-Center
    Handbook of Star Forming Regions Vol. I Astronomical Society of the Pacific, c 2008 Bo Reipurth, ed. Star Formation and Molecular Clouds towards the Galactic Anti-Center Bo Reipurth Institute for Astronomy, University of Hawaii 640 N. Aohoku Place, Hilo, HI 96720, USA Chi-Hung Yan Institute of Astronomy and Astrophysics, Academia Sinica P.O. Box 23-141, Taipei 10617, Taiwan National Taiwan Normal University 88 Sec. 4, Tingzhou Road, Taipei, 11766, Taiwan Abstract. The Galactic Anticenter region hosts a a number of massive molecular cloud complexes, some of which are currently actively forming stars. Two major OB associations, Gem OB1 and Aur OB1, are found in this direction, each with numerous massive stars and a supernova remnant. The dominant region of star formation is cen- tered around the Sh 2-235 complex and the nearby regions AFGL 5142, 5144, and 5157 towards Aur OB1. Studies of these regions have long been affected by relatively poor distance determinations, although there is general consensus that most regions are lo- cated at distances between 1.5 and 2 kpc. A number of well-known, relatively isolated Herbig Ae/Be stars are found in this general direction, including RR Tau, HD 250550, and LkHα 208. 1. Overview The region towards the Galactic Anticenter is rich in molecular clouds and star forma- tion activity, although most is located at a considerable distance. In this chapter, we summarize key features of the principal regions of star formation out to approximately 2 kpc. A number of very interesting regions exist at larger distances, but those are be- yond the scope of this review.

Im Gegensatz zu kleineren Teilchen verbleiben sie auf Trajektorien, die der des Ko- meten sehr ahnlich¨ sind. Dem Beobachter erscheinen sie als eine schmale Struktur entlang des projizierten Kometenorbits, die als Staub-Trail bezeichnet wird. Die erste im Rahmen dieser Arbeit untersuchte Beobachtung wurde im April 2004 in sichtbarem Licht mit dem Wide Field Imager am ESO/MPG-2.2m-Teleskop auf La Silla (Chile) durchgefuhrt.¨ Der Abstand des Kometen von der Sonne betrug zu diesem Zeitpunkt 4.7 A.E. Zwei weitere Beobachtungen wurden im August 2005 und im April 2006 im mittleren Infrarot (24 µm) ausgefuhrt¨ mit der MIPS-Kamera auf dem Spitzer-Weltraumteleskop. In beiden Fallen¨ war der Komet 5.7 A.E. von der Sonne entfernt. In der dazwischenliegenden Zeit, im No- vember 2005, hatte er das Aphel passiert. Zur Interpretation der Daten werden simulierte Trailbilder erzeugt.

  • 1968Apjs...15..131G OH ABSORPTION in the GALAXY* W
    OH ABSORPTION IN THE GALAXY* W. Miller Gossf Radio Astronomy Laboratory, University of California, Berkeley 1968ApJS...15..131G Received April 26, 1967 ABSTRACT A survey of northern hemisphere radio sources for 18-cm OH absorption has been completed using the 85-foot Hat Creek telescope of the University of California. The observations were made with the 100-channel receiver with frequency resolutions of 10 kHz (1.8 km/s) and 2 kHz (0.36 km/s). Galactic OH absorption lines have been found in 26 galactic sources and two extragalactic sources (W7 and Cyg A): W1 (NGC 7822), W9 (Tau A), W10 (Orion A), W12 (NGC 2024), W14 (IC 443), W22 (NGC 6357), W28, W29 (M8), W30, W31, W33, W35 (NGC 6604), W37 (M16), W38 (M17), W41, W42, W43, W44, W47, W66, W67, W69, W72, W73, W80 (NGC 7000), and W81 (Cas A). Four of these sources contain OH emission in the main lines (1667 MHz and 1665 MHz) in addition to the absorption: Orion A at 1667 and 1665 MHz, W33 at 1667 and 1665 MHz, W42 at 1667 MHz, and W43 at 1667 and 1665 MHz. The W42, W33, and Orion (1667 MHz) sources differ from the previously discovered emission sources in that the emission is at the high-velocity side of one of the absorption lines. For the sources W10, W12, W22, W28, W41, W43, W44, W51, and W81 all four lines of the OH multi- plet have been observed. Most of the sources show normal intensity ratios in the main lines. Except for W12 and W22 all the sources show emission in the 1612 MHz and/or 1720 MHz satellite lines.
