X-rays from T Tau: A test case for accreting T Tauri stars
M. Guedel, S. L. Skinner, S. Yu. Mel'nikov +3
We test models for the generation of X-rays in accreting T Tauri stars (TTS), using X-ray data from the classical TTS T Tau. High-resolution spectroscopy from the Reflection Gratin…
X-ray Emission from T Tauri Stars and the Role of Accretion: Inferences from the XMM-Newton Extended Survey of the Taurus Molecular Cloud
A. Telleschi, M. Guedel, K. R. Briggs +2
T Tau stars display different X-ray properties depending on whether they are accreting (classical T Tau stars; CTTS) or not (weak-line T Tau stars; WTTS). We use data from the XMM-…
The Cosmic Evolution Survey (COSMOS) -- Overview
N. Scoville, H. Aussel, M. Brusa +19
The Cosmic Evolution Survey (COSMOS) is designed to probe the correlated evolution of galaxies, star formation, active galactic nuclei (AGN) and dark matter (DM) with large-scale s…

zCOSMOS is a large redshift survey that is being undertaken in the COSMOS field using 600 hours of observation with the VIMOS spectrograph on the 8-m VLT. The survey is designed to…
GALEX Ultraviolet Photometry of Globular Clusters in M31: Three Year Results and a Catalog
Soo-Chang Rey, R. Michael Rich, Sangmo T. Sohn +23
We present ultraviolet (UV) photometry of M31 globular clusters (GCs) found in 23 Galaxy Evolution Explorer (GALEX) images covering the entirety of M31. We detect 485 and 273 GCs (…
Constraining Dark Energy by Combining Cluster Counts and Shear-Shear Correlations in a Weak Lensing Survey
Wenjuan Fang, Zoltan Haiman
We study the potential of a large future weak-lensing survey to constrain dark energy properties by using both the number counts of detected galaxy clusters (sensitive primarily to…
MoLUSC: A MOck Local Universe Survey Constructor
T. Sousbie, H. Courtois, G. Bryan +1
This paper presents MoLUSC, a new method for generating mock galaxy catalogs from a large scale ( Mpc) dark matter simulation, that requires only modest CPU tim…
Ultraviolet Detection of the Tidal Disruption of a Star by a Supermassive Black Hole
S. Gezari, D. C. Martin, B. Milliard +10
A supermassive black hole in the nucleus of a galaxy will be revealed when a star passes close enough to be torn apart by tidal forces and a flare of radiation is emitted by the st…
Hot Jupiter Variability in Eclipse Depth
Emily Rauscher, Kristen Menou, James Y-K. Cho +2
Physical conditions in the atmospheres of tidally-locked, slowly-rotating hot Jupiters correspond to dynamical circulation regimes with Rhines scales and Rossby deformation radii c…
Toward Eclipse Mapping of Hot Jupiters
Emily Rauscher, Kristen Menou, Sara Seager +3
Recent Spitzer infrared measurements of hot Jupiter eclipses suggest that eclipse mapping techniques could be used to spatially resolve the day-side photospheric emission of these…
COSMOS : Hubble Space Telescope Observations
N. Scoville, A. Benson, A. W. Blain +50
The Cosmic Evolution Survey (COSMOS) was initiated with an extensive allocation (590 orbits in Cycles 12-13) using the Hubble Space Telescope (HST) for high resolution imaging. Her…
The X-ray Properties of Early-Type Galaxies in the Extended Chandra Deep Field-South
B. D. Lehmer, W. N. Brandt, D. M. Alexander +8
We investigate the evolution over the last 6.3 Gyr of cosmic time (i.e., since z ~ 0.7) of the average X-ray properties of early-type galaxies within the Extended Chandra Deep Fiel…
Observations of the Unidentified TeV Gamma-Ray Source TeV J2032+4130 with the Whipple Observatory 10 m Telescope
A. Konopelko, R. W. Atkins, G. Blaylock +58
We report on observations of the sky region around the unidentified TeV gamma-ray source TeV J2032+4130 carried out with the Whipple Observatory 10 m atmospheric Cherenkov telescop…
Spectral properties of X-ray bright variable sources in the Taurus Molecular Cloud
E. Franciosini, I. Pillitteri, B. Stelzer +7
We analyze 19 bright variable X-ray sources detected in the XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST), in order to characterize the variations with time of th…
The Effect of Cluster Environment on Galaxy Evolution in the Pegasus I Cluster
Lorenza Levy, James A. Rose, Jacqueline H. van Gorkom +1
We present HI observations of 54 galaxies in the Pegasus cluster. The observations include single dish HI measurements, obtained with the Arecibo telescope for all 54 galaxies in t…
Correlation between X-ray Lightcurve Shape and Radio Arrival Time in the Vela Pulsar
A. Lommen, J. Donovan, C. Gwinn +6
We report the results of simultaneous observations of the Vela pulsar in X-rays and radio from the RXTE satellite and the Mount Pleasant Radio Observatory in Tasmania. We sought co…
Exploring Broadband GRB Behavior During gamma-ray Emission
S. A. Yost, H. F. Swan, E. S. Rykoff +44
The robotic ROTSE-III telescope network detected prompt optical emission contemporaneous with the gamma-ray emission of Swift events GRB051109A and GRB051111. Both datasets have co…
