Armandroff It is a pleasure to welcome you to the W. M. Keck Observatory Annual Report for 2011. Keck Observatory (WMKO) operates twin 10-meter optical/infrared telescopes nightly on the excellent site of Mauna Kea, renowned for its extremely dark skies and superb image quality. The two telescopes feature a highly capable suite of advanced instrumentation. For the past 19 years, Keck Observatory has played a leading role in astronomy and astrophysics worldwide. Four objective metrics demonstrate Keck Observatory’s scientific success: 1) In independent studies of observatory scientific productivity, we consistently rank highest in the number of papers per telescope per year of ground-based observatories. For example in fiscal year 2011, the two Keck telescopes produced 278 papers, or 139 papers per telescope. This dramatically exceeds all other U.S. facilities and also exceeds all other observatories worldwide. 2) In independent studies, we generate the highest total impact per telescope of ground-based observatories, taking into account not only the number of publications but also how often each publication is cited in subsequent research. 3) WMKO dominates the emerging field of laser guide star adaptive optics (LGS AO) science. Three-quarters of all LGS AO papers worldwide from 2004 through 2011 are based on Keck data. 4) The large impact of the Keck telescopes on astronomy education is well illustrated by the 240 PhD theses produced using our data from 1994 to 2011. A key component of our organization’s success has been the highly effective partnership between private and federal institutions that provide financial support, as well as the robust scientific collaboration between Keck Observatory and our partner universities (Caltech, the University of California, and the University of Hawaii) and the community of observers that participate through NASA and the National Science Foundation. The theme for this year’s Annual Report is “The Year of the Supernovae.” The 2011 Nobel Prize in Physics was awarded to Saul Perlmutter, Brian Schmidt, and Adam Riess for their pioneering studies of supernovae at cosmological distances that demonstrated that the expansion of the universe is accelerating. Keck Observatory played an essential role in this transformative research. A Nobel Prize recognizing research in astronomy and astrophysics is a very rare This graph reflects the science productivity of Laser Guide honor. In addition, the closest Type Ia supernova in forty Star Adaptive Optics (LGS AO) and the dominance of Keck years exploded in 2011 and was studied using the Keck II Observatory in this breakthrough field of astronomy research.

Armed Three quarters of all LGS AO papers worldwide from 2004 through 2011 are based on Keck data. with this unique Keck dataset, astronomers have constrained theories for the physical mechanism that produces these cosmic lighthouses, so vital to probing the distant universe. Inside this report, we will reveal more about supernovae, the tools we use at Keck Observatory to probe them, and the driving spirit of our professional staff that makes this Here Dr. Brian Schmidt delivers his Nobel lecture in Stockholm, exciting research possible. Sweden in late 2011. Schmidt, along with Saul Perlmutter and Adam Riess, was honored with the 2011 Nobel Prize in Keck Observatory made strong progress on technical Physics for describing the accelerating expansion rate of the universe. Their pioneering research was based fundamentally achievements in 2011, particularly regarding two of our on observations made with the Keck Observatory. multi-year projects to develop new observing capabilities. The Multi Object Spectrograph for Infrared Exploration (MOSFIRE) and the next generation Laser Guide Star Adaptive Optics (LGS AO) system for the Keck I telescope neared full functionality. Both MOSFIRE and the new LGS AO system are scheduled for scientific use by the summer of 2012. Our observer community relishes the opportunity to apply these new tools to address major open questions in astronomy today. There remains much important astronomy research to be done. Our Scientific Strategic Plan and a recent national decadal assessment of research priorities have highlighted T 2011 the following key questions to be addressed in the coming R decade, using both existing and planned instrumentation: L REPO • How diverse are planetary systems? A • Do habitable worlds exist around other stars and can we ANNU identify the telltale signs of life on an exoplanet? • What were the first objects to light up the universe and when did they do it? bservatory O • How do black holes grow, radiate and influence their ECK surroundings? W.M. K W.M. • What is the fossil record of galaxy assembly and evolution from the first stars to the present? 4 • How does normal matter cycle in and out of galaxies and what does it do while it is there? It is our intention to sustain Keck Observatory as one of the crown jewels of U.S. astronomy for the next ten years and well beyond. I strongly believe that we will maintain the Keck Observatory’s leadership in developing and deploying new instrumentation and adaptive optics systems to address new scientific challenges and to remain important discovery tools for the U.S. astronomy community. However, there is a shortage of funding to develop new instrumentation and AO systems. I am grateful for our philanthropic individuals and foundations, and federal agencies, for their support in initiatives that are on the leading edge and that meaningfully advance the priority research questions in astronomy today. In closing, astronomy is tremendously rich with opportunities for discoveries which bring a deeper understanding of the mechanisms, history and future of the universe.

Although partially studied by a few Chinese scholars, it has never been fully displayed and discussed in the Western world. This set of sky maps (12 hour angle maps in quasi-cylindrical projection and a circumpolar map in azimuthal projection), displaying the full sky visible from the Northern hemisphere, is up to now the oldest complete preserved star atlas from any civilisation. It is also the first known pictorial representation of the quasi-totality of the Chinese constellations. This paper describes the history of the physical object – a roll of thin paper drawn with ink. We analyse the stellar content of each map (1339 stars, 257 asterisms) and the texts associated with the maps. We establish the precision with which the maps are drawn (1.5 to 4° for the brightest stars) and examine the type of projections used.

Open clusters are an important tool for studying the chemical evolution of the Galactic disk. Metallicity estimates are available for about ten percent of the currently known open clusters. These metallicities are based on widely differing methods, however, which introduces unknown systematic effects. Aims. In a series of three papers, we investigate the current status of published metallicities for open clusters that were derived from a variety of photometric and spectroscopic methods. The current article focuses on spectroscopic methods. The aim is to compile a comprehensive set of clusters with the most reliable metallicities from high-resolution spectroscopic studies. This set of metallicities will be the basis for a calibration of metallicities from different methods. Methods. The literature was searched for [Fe/H] estimates of individual member stars of open clusters based on the analysis of high-resolution spectra. For comparison, we also compiled [Fe/H] estimates based on spectra with low and intermediate resolution.

  • Filter Performance Comparisons for Some Common Nebulae
    Filter Performance Comparisons For Some Common Nebulae By Dave Knisely Light Pollution and various “nebula” filters have been around since the late 1970’s, and amateurs have been using them ever since to bring out detail (and even some objects) which were difficult to impossible to see before in modest apertures. When I started using them in the early 1980’s, specific information about which filter might work on a given object (or even whether certain filters were useful at all) was often hard to come by. Even those accounts that were available often had incomplete or inaccurate information. Getting some observational experience with the Lumicon line of filters helped, but there were still some unanswered questions. I wondered how the various filters would rank on- average against each other for a large number of objects, and whether there was a “best overall” filter. In particular, I also wondered if the much-maligned H-Beta filter was useful on more objects than the two or three targets most often mentioned in publications. In the summer of 1999, I decided to begin some more comprehensive observations to try and answer these questions and determine how to best use these filters overall. I formulated a basic survey covering a moderate number of emission and planetary nebulae to obtain some statistics on filter performance to try to address the following questions: 1. How do the various filter types compare as to what (on average) they show on a given nebula? 2. Is there one overall “best” nebula filter which will work on the largest number of objects? 3.

Reach,1 Le Ngoc Tram,1 Matthew Richter,2 Antoine Gusdorf,3 Curtis DeWitt,1 1Universities Space Research Association, MS 232-11, Moffett Field, CA 94035, USA 2University of California, Davis, CA USA 3Observatoire de Paris, Ecole´ normale sup´erieure, Sorbonne Universit´e,CNRS, LERMA, 75005 Paris, France ABSTRACT Supernovae from core-collapse of massive stars drive shocks into the molecular clouds from which the stars formed. Such shocks affect future star formation from the molecu- lar clouds, and the fast-moving, dense gas with compressed magnetic fields is associated with enhanced cosmic rays. This paper presents new theoretical modeling, using the Paris-Durham shock model, and new observations at high spectral resolution, using the Stratospheric Observatory for Infrared Astronomy (SOFIA), of the H2 S(5) pure rota- tional line from molecular shocks in the supernova remnant IC 443. We generate MHD models for non-steady-state shocks driven by the pressure of the IC 443 blast wave into gas of densities 103 to 105 cm−3. We present the first detailed derivation of the shape of the velocity profile for emission from H2 lines behind such shocks, taking into account the shock age, preshock density, and magnetic field. For preshock densities 103{105 −3 cm , the H2 emission arises from layers that extend 0.01{0.0003 pc behind the shock, respectively. The predicted shifts of line centers, and the line widths, of the H2 lines range from 20{2, and 30{4 km s−1, respectively.

  • Mode Changing and Giant Pulses Found in a Millisecond Pulsar 17 July 2018, by Tomasz Nowakowski
    Mode changing and giant pulses found in a millisecond pulsar 17 July 2018, by Tomasz Nowakowski between two or more quasi-stable modes of emission. To date, mode changing has been only observed in normal pulsars. However, a recent study conducted by a team of astronomers led by Nikhil Mahajan of the University of Toronto in Canada, shows the mode changing process could be also present in millisecond pulsars, as they observed that the pulse profile of pulsar PSR B1957+20 switches between two modes. Discovered in 1988, PSR B1957+20, also known as the "Black Widow Pulsar", is a 1.6 ms eclipsing binary millisecond pulsar in the constellation Sagitta. It orbits with a brown dwarf companion with a period of 9.2 hours with an eclipse duration of approximately 20 minutes.

  • Exodata: a Python Package to Handle Large Exoplanet Catalogue Data
    ExoData: A Python package to handle large exoplanet catalogue data Ryan Varley Department of Physics & Astronomy, University College London 132 Hampstead Road, London, NW1 2PS, United Kingdom [email protected] Abstract Exoplanet science often involves using the system parameters of real exoplanets for tasks such as simulations, fitting routines, and target selection for proposals. Several exoplanet catalogues are already well established but often lack a version history and code friendly interfaces. Software that bridges the barrier between the catalogues and code enables users to improve the specific repeatability of results by facilitating the retrieval of exact system parameters used in an arti- cles results along with unifying the equations and software used. As exoplanet science moves towards large data, gone are the days where researchers can recall the current population from memory. An interface able to query the population now becomes invaluable for target selection and population analysis. ExoData is a Python interface and exploratory analysis tool for the Open Exoplanet Cata- logue. It allows the loading of exoplanet systems into Python as objects (Planet, Star, Binary etc) from which common orbital and system equations can be calculated and measured parame- ters retrieved. This allows researchers to use tested code of the common equations they require (with units) and provides a large science input catalogue of planets for easy plotting and use in research. Advanced querying of targets are possible using the database and Python programming language. ExoData is also able to parse spectral types and fill in missing parameters according to programmable specifications and equations. Examples of use cases are integration of equations into data reduction pipelines, selecting planets for observing proposals and as an input catalogue to large scale simulation and analysis of planets.

  • Highlights and Discoveries from the Chandra X-Ray Observatory1
    Highlights and Discoveries from the Chandra X-ray Observatory1 H Tananbaum1, M C Weisskopf2, W Tucker1, B Wilkes1 and P Edmonds1 1Smithsonian Astrophysical Observatory, 60 Garden Street, Cambridge, MA 02138. 2 NASA/Marshall Space Flight Center, ZP12, 320 Sparkman Drive, Huntsville, AL 35805. Abstract. Within 40 years of the detection of the first extrasolar X-ray source in 1962, NASA’s Chandra X-ray Observatory has achieved an increase in sensitivity of 10 orders of magnitude, comparable to the gain in going from naked-eye observations to the most powerful optical telescopes over the past 400 years. Chandra is unique in its capabilities for producing sub-arcsecond X-ray images with 100-200 eV energy resolution for energies in the range 0.08<E<10 keV, locating X-ray sources to high precision, detecting extremely faint sources, and obtaining high resolution spectra of selected cosmic phenomena. The extended Chandra mission provides a long observing baseline with stable and well-calibrated instruments, enabling temporal studies over time-scales from milliseconds to years. In this report we present a selection of highlights that illustrate how observations using Chandra, sometimes alone, but often in conjunction with other telescopes, have deepened, and in some instances revolutionized, our understanding of topics as diverse as protoplanetary nebulae; massive stars; supernova explosions; pulsar wind nebulae; the superfluid interior of neutron stars; accretion flows around black holes; the growth of supermassive black holes and their role in the regulation of star formation and growth of galaxies; impacts of collisions, mergers, and feedback on growth and evolution of groups and clusters of galaxies; and properties of dark matter and dark energy.
