  • News from the High Plains
    Department of Physics & Astronomy Greetings Alumni & Friends, February 2014 Physics & Astronomy at 7200’ is alive and kicking. The enclosed plot shows how News from the our student population has seen significant growth over the past decade to a present total of 115, including 38 graduate students (see also the Sputnik-era spike!). This High Plains growth has gone hand-in-hand with the University’s decision to recommit to physics. Our astronomy program now has expertise in star formation, planetary formation, galaxies, quasars, instrumentation, and cosmology. UW physicists work on a wide array of areas in condensed matter physics and biophysics. Much of the focus has been on developing and understanding nanostructures geared toward efficient energy transportation and conversion (e.g., solar cells). Our physics faculty have also been working with the departments of Chemistry, Chemical & Petroleum Engineering, and Mechanical Engineering to develop a cross-college, interdisciplinary Materials Science and Engineering program. This program allows students to take courses from multiple departments, carry out collaborative research, and ultimately pursue a terminal degree in their home departments with a concentration in Materials Science. In terms of infrastructure, our program is almost unrecognizable from where it stood just a few years ago. We now have a first-class nano-fabrication and characterization lab that includes key pieces of equipment such as an electron-beam evaporator, X-ray diffractometer, reactive ion etcher, chemical vapor deposition systems, mask aligner, etc. Our newest faculty member, TeYu Chien, is building up a lab centered around Spring Graduates a state-of-the-art scanning tunneling microscope. Our observatory WIRO is also continuing to see upgrades.

  • Dwarfs Walking in a Row the filamentary Nature of the NGC 3109 Association

We find that the original members of the NGC 3109 association, together with the recently discovered and adjacent dwarf irregular Leo P, form a very tight and elongated configuration in space. All these galaxies lie within ∼100 kpc of a line that is '1070 kpc long, from one extreme (NGC 3109) to the other (Leo P), and they show a gradient in the Local Group standard of rest velocity with a total amplitude of 43 km s−1 Mpc−1, and a rms scatter of just 16.8 km s−1. It is shown that the reported configuration is exceptional given the known dwarf galaxies in the Local Group and its surroundings.

  • Recommendations for NASA/NSF Investment in Precise Radial Velocity Hardware and Facilities
    Recommendations for NASA/NSF Investment in Precise Radial Velocity Hardware and Facilities William Cochran, Dawn Gelino, Sara Heap, John Johnson, David Latham On behalf of the Precision Radial Velocity Community Penn State University and the NASA Exoplanet Science Institute recently hosted a workshop on precision radial velocity (PRV) for the detection and characterization of exoplanets. The workshop was attended by more than 100 researchers from around the world (http://exoplanets.astro.psu.edu/workshop/program.html) and coincided with the release of the ASTRO2010 Decadal report that laid great emphasis on the importance of radial velocity measurements. The US PRV community, many of whom attended this conference, have prepared this series of recommendations for new PRV instrumentation and observing opportunities that will maintain US competitiveness and leadership in a field identified as critical by the ASTRO2010 decadal report. National Research Council 2010 Decadal Survey Report One of the top three scientific objectives of the National Research Council’s 2010 Decadal Survey of Astronomy and Astrophysics is “New Worlds: Seeking Nearby, Habitable Planets.” The report describes a “New Worlds Technology Development Program” in which “NASA and NSF should support an aggressive program of ground-based high-precision radial velocity surveys of nearby stars to identify potential candidates.” Two sets of quotes from the report are particularly relevant: “…The first task on the ground is to improve the precision radial velocity method by which

  • Dwarf Galaxies of the Local Group Offer the Best Opportunity to Study a Representative Sample of These Important, but by Nature, Inconspicuous Galaxies in Detail
    DWARF GALAXIES OF THE LOCAL GROUP Mario Mateo KEY WORDS: Stellar Populations, Local Group Galaxies, Photometry, Galaxy Formation, Spectroscopy, Dark Matter, Interstellar Medium Shortened Title: LOCAL GROUP DWARFS Send Proofs To: Mario Mateo Department of Astronomy; University of Michigan Ann Arbor, MI 48109-1090 Phone: 313 936-1742; Fax: 313 763-6317 Email: [email protected] ABSTRACT The Local Group (LG) dwarf galaxies offer a unique window to the detailed properties of the most common type of galaxy in the Universe. In this review, I update the census of LG dwarfs based on the most recent distance and radial velocity determinations. I then discuss the detailed properties of this sample, including (a) the integrated photometric parameters and optical structures of these galaxies, (b) the content, nature and distribution of their ISM, (c) their heavy-element abundances derived from both stars and nebulae, (d) the arXiv:astro-ph/9810070v1 5 Oct 1998 complex and varied star-formation histories of these dwarfs, (e) their internal kinematics, stressing the relevance of these galaxies to the dark-matter problem and to alternative interpretations, and (f) evidence for past, ongoing and future interactions of these dwarfs with other galaxies in the Local Group and beyond. To complement the discussion and to serve as a foundation for future work, I present an extensive set of basic observational data in tables that summarize much of what we know, and what we still do not know, about these nearby dwarfs. Our understanding of these galaxies has grown impressively in the past decade, but fundamental puzzles remain that will keep the Local Group at the forefront of galaxy evolution studies for some time.

  • Naming Objects in Thesky
    - ; Chapter 4 Naming ObjectS in TheSky Astronomers need to be able to assimilate and exchange information about specific objects in the sky. Many systems have been devised over the last few thousand years to identify and name the most conspicuous ones. As our technology has advanced, studies of astronomical objects have become more precise. Today it is common for astronomers to assign numerous designations to a single celestial body. Humans have observed the stars for millennia. Our ancestors named the bright stars as well as larger groups of stars called constellations. As we said in Chapter 1, the ancients named many of the constellations after mythological beasts, gods, demigods, and ordinary household objects. Astronomers continue to use the names of the constellations first recorded by ancient astronomers thousands of years ago. It is here that we may begin to learn about where things are located in the sky and how they are named. Astronomers officially recognize 88 distinct constellations today. TheSky displays all of them quite accurately. From the mid-northern latitudes, you can see over half of them. Most are visible every night from your location at some time during the night. TheSky helps you to find them but you must go outside on any clear night throughout the year and look for them yourself. About a half dozen or so constellations are visible every night from 40°north latitude all year round. These are the circumpolar constellations. They are all located in the northern sky near the North Star, Polaris. Using TheSky will definitely help you locate all these constellations easily during any season of the year.
