A Wide-Field Study of the z~0.8 Cluster RX J0152.7-1357: the Role of Environment in the Formation of the Red-Sequence
Shannon G. Patel, Daniel D. Kelson, Bradford P. Holden +4
[ABRIDGED] We present the first results from the largest spectroscopic survey to date of an intermediate redshift galaxy cluster, the z=0.834 cluster RX J0152.7-1357. We use the co…
Biases and Uncertainties in Physical Parameter Estimates of Lyman Break Galaxies from Broad-band Photometry
Seong-Kook Lee, Rafal Idzi, Henry C. Ferguson +3
We investigate the biases and uncertainties in estimates of physical parameters of high-redshift Lyman break galaxies (LBGs), such as stellar mass, mean stellar population age, and…

P. Padovani, V. Mainieri, P. Tozzi +5
We present a detailed analysis of 256 radio sources from our deep (flux density limit of 42 microJy at the field centre at 1.4 GHz) Chandra Deep Field South 1.4 and 5 GHz VLA surve…
Modeling H2 Fluorescence in Planetary Atmospheres with Partial Frequency Redistribution
R. E. Lupu, P. D. Feldman, S. R. McCandliss +1
We present the modeling of partial frequency redistribution (PRD) effects for the fluorescent emission lines of molecular hydrogen, the general computational approximations, and th…
Essential observations of the Lyman continuum
Stephan R. McCandliss
Concurrent observations of Lyman continuum (LyC) and Lyman-alpha (Lya) emission escaping from star-forming systems at low redshift are essential to understanding the physics of rei…
Variable Intrinsic Absorption in Mrk 279
Jennifer E. Scott, Nahum Arav, Jack R. Gabel +5
We examine the variability in the intrinsic absorption in the Seyfert 1 galaxy Mrk 279 using three epochs of observations from the Far Ultraviolet Spectroscopic Explorer (FUSE) and…
Reaction of Accretion Disks to Abrupt Mass Loss During Binary Black Hole Merger
Sean M. O'Neill, M. Coleman Miller, Tamara Bogdanovic +2
The association of an electromagnetic signal with the merger of a pair of supermassive black holes would have many important implications. For example, it would provide new informa…
Feast and Famine: Regulation of Black Hole Growth in Low Redshift Galaxies
Guinevere Kauffmann, Timothy M. Heckman
We analyze the observed distribution of Eddington ratios as a function of supermassive black hole mass for a large sample of nearby galaxies drawn from the Sloan Digital Sky Survey…
A Map of the Integrated Sachs-Wolfe Signal from Luminous Red Galaxies
Benjamin R. Granett, Mark C. Neyrinck, István Szapudi
We construct a map of the time derivative of the gravitational potential traced by SDSS Luminous Red Galaxies. The potential decays on large scales due to cosmic acceleration, leav…
The Seventh Data Release of the Sloan Digital Sky Survey
K. Abazajian
This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDS…
Spectroscopy of High-Redshift Supernovae from the ESSENCE Project: The First Four Years
R. J. Foley, T. Matheson, S. Blondin +23
We present the results of spectroscopic observations from the ESSENCE high-redshift supernova (SN) survey during its first four years of operation. This sample includes spectra of…
Wide Area X-ray Surveys for AGN and Starburst Galaxies
A. Ptak
While often the point sources in X-ray surveys are dominated by AGN, with the high sensitivity of modern X-ray telescopes such as Chandra and XMM-Newton normal/starburst galaxies a…
Discovery of photospheric CaX emission lines in the far-UV spectrum of the hottest known white dwarf (KPD0005+5106)
K. Werner, T. Rauch, J. W. Kruk
For the first time, we have identified photospheric emission lines in the far-UV spectrum of a white dwarf. They were discovered in the Far Ultraviolet Spectroscopic Explorer spect…
Quenching of Star Formation
Vivienne Wild, Tamas Budavari, Jeremy Blaizot +5
In the last decade we have seen an enormous increase in the size and quality of spectroscopic galaxy surveys, both at low and high redshift. New statistical techniques to analyse l…
Ground-based CCD astrometry with wide field imagers. III. [email protected] proper-motion catalog of the globular cluster omega Centauri
A. Bellini, G. Piotto, L. R. Bedin +6
Omega Centauri is the most well studied Globular Cluster because of its numerous puzzling features. Intensive spectroscopic follow-up observing campaigns targeting stars at differe…
Variable Evolved Stars and YSOs Discovered in the Large Magellanic Cloud using the SAGE Survey
Uma P. Vijh, M. Meixner, B. Babler +13
We present initial results and source lists of variable sources in the Large Magellanic Cloud (LMC) for which we detect thermal infrared variability from the SAGE (Surveying the Ag…
Five-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Bayesian Estimation of CMB Polarization Maps
J. Dunkley, D. N. Spergel, E. Komatsu +17
We describe a sampling method to estimate the polarized CMB signal from observed maps of the sky. We use a Metropolis-within-Gibbs algorithm to estimate the polarized CMB map, cont…
Galaxy Zoo: Disentangling the Environmental Dependence of Morphology and Colour

We analyze the environmental dependence of galaxy morphology and colour with two-point clustering statistics, using data from the Galaxy Zoo, the largest sample of visually classif…
Probing Spectroscopic Variability of Galaxies & Narrow-Line Active Galactic Nuclei in the Sloan Digital Sky Survey
Ching-Wa Yip, Andrew Connolly, Daniel Vanden Berk +10
Under the unified model for active galactic nuclei (AGNs), narrow-line (Type 2) AGNs are, in fact, broad-line (Type 1) AGNs but each with a heavily obscured accretion disk. We woul…
