The oval ribbons toward the top and bottom of the image shows the location of auroral activity near Saturn’s poles. This activity is analogous to Earth’s aurora borealis and aurora australis, the so-called “northern” and “southern lights,” and is caused by energetic particles from the sun trapped in Saturn’s magnetic field. 3 4 EXECUTIVE SUMMARY associates authored or co-authored a total of 204 refereed, scholarly papers in the disciplines’ most The Department of Astronomy teaches science to prestigious journals. hundreds of non-science majors from throughout the university, and runs one of the largest astronomy degree The funding of the Astronomy Department, the Center programs in the country.

Letter from Astronomy Planetary and Space Sciences In
City of Tucson Planning Commission – Citizen Sign Code Committee Joint Subcommittee on Sign Code Revision 201 North Stone Ave. Tucson, AZ 85701 November 4, 2016 [email protected] Dear Members of the Joint Subcommittee: The consortium of professional research organizations that rely on Arizona dark skies, APSS, wants to make a few points with respect to your considerations about revising the City of Tucson Sign Code: We represent a significant economic sector in Southern Arizona. We strongly urge separating the pace of the revisions necessitated by Reed v. Town of Gilbert from those of process and other major changes, out of concern for the unintended consequences of substantially increasing glare from lighted signs. We encourage you to include the protection of the dark night sky in the statement of purpose, so that it is a clear aspect of maintaining the character of Tucson. We also encourage the inclusion of the already mature language about electronic message centers, and any revisions that will have the effect of reducing the amount of artificial sky glow. Attached is a previous economic impact study for our professional research enterprise. We note that the $250M per year impact is statewide, but with a substantial concentration in Southern Arizona. It is ongoing: NASA and the Department of Energy have each recently committed tens of millions of dollars for reinvestment in Kitt Peak instrumentation, based on its being a dark sky site. The astronomy, planetary, and space science enterprise has been a strong driver for other key industry sectors, such as the Optics Industry. It also impacts the tourist industry. -

Although the luminosities and brightness fluctuations of assumes a black-hole mass, stellar mass-to-light ratio and dark-matter quasars in the early Universe suggest that some were powered by profile, and generates a library of time-averaged stellar orbits in the black holes with masses greater than 10 billion solar masses1,2, the resulting gravitational potential.

Commissioning of the MMT Ground-Layer and Laser Tomography Adaptive Optics Systems
Commissioning of the MMT ground-layer and laser tomography adaptive optics systems N. Mark Milton1, Michael Lloyd-Hart1, Christoph Baranec2, Thomas Stalcup1,KeithPowell1, Don McCarthy1, Craig Kulesa1,andKeithHege1 1 Center for Astronomical Adaptive Optics, Steward Observatory, 933 N. Cherry Ave., Tucson, Arizona 85721 2 Caltech Optical Observatories, California Institute of Technology, 1200 E. California Blvd., Pasadena, California 91125 ABSTRACT A multi-laser adaptive optics system, at the 6.5 m MMT telescope, has been undergoing commissioning in preparation for wide-field, partially corrected as well as narrow-field, diffraction limited science observations in the thermal and near infrared. After several delays due to bad weather, we have successfully closed the full high order ground-layer adaptive optics (GLAO) control loop for the first time in February 2008 using five Rayleigh laser guide stars and a single tilt star. Characterization and automated correction of static aberrations such as non-common path errors were addressed in May 2008. Calibration measurements in preparation for laser tomography adaptive optics (LTAO) operation are planned for the fall of 2008 along with the start of shared-risk GLAO science observations. We present the results of GLAO observations with the PISCES imager, a 1 − 2.5 µm camera with a field of view of 110 arc seconds. The status of the remaining GLAO commissioning work is also reviewed. Finally, we present plans for commissioning work to implement the LTAO operating mode of the system. Keywords: adaptive optics, ground-layer adaptive optics, laser guide stars 1. INTRODUCTION Until very recently, adaptive optics (AO) systems, in operation at large astronomical telescopes, have used a single guide star to measure the atmospheric induced aberrations that degrade the long exposure imaging performance of science observations. -

Yale University Astronomy Department Newsletter Vol. 5 Spring 2014 No. 1 Kenney captures dwarf galaxy in the act of dying Professor Jeff Kenney has found concrete evidence that dwarf galaxies stop forming stars due to the process known as ram pressure stripping. Kenney and his team of researchers have caught the Virgo Cluster galaxy IC3418 in the act of transforming from a dwarf irregular galaxy into a dwarf elliptical galaxy. The metamor- phosis happens as gas is stripped from the galaxy through ram pressure, a forceful wind that is caused by the collision of the gas in the galaxy with the gas in intracluster space. With no gas available for star formation, dwarf elliptical galax- ies are considered “dead.” Therefore, Kenney and his team are witnessing the first clear example of a dwarf galaxy in the act of dying. “We think we’re witnessing a critical stage in the transforma- X-ray image showing hot gas in the Virgo cluster with an enlarged UV image of dwarf galaxy IC3418 sporting tion of a gas-rich dwarf irregular galaxy (SEE DWARF, p. 4) a tail of recently formed stars. J. Kenney and P. Jachym. Massive black holes alive and well in dwarf galaxies Dwarf galaxies may be small, but astronomers now know that they can hold massive black holes. Yale astronomer Marla Geha and collaborators have identified more than 100 dwarf galaxies that show signs of hosting mas- sive black holes, a discovery that challenges the idea that they exist only in much bigger galaxies. “These galaxies are comparable in size to the Magellanic Clouds, dwarf satellite galaxies of the Milky Way,” said Geha, associate professor of astronomy. -
