The Faint End of the Quasar Luminosity Function at z~4
Eilat Glikman, Milan Bogosavljevic, S. G. Djorgovski +4
We have conducted a spectroscopic survey to find faint quasars (-26.0 < M_{1450} < -22.0) at redshifts z=3.8-5.2 in order to measure the faint end of the quasar luminosity function…
A Physical Model for z~2 Dust Obscured Galaxies
Desika Narayanan, Arjun Dey, Christopher Hayward +8
We present a physical model for the origin of z~2 Dust-Obscured Galaxies (DOGs), a class of high-redshift ULIRGs selected at 24 micron which are particularly optically faint (24/R>…
Infrared Luminosities and Dust Properties of z ~ 2 Dust-Obscured Galaxies
R. S. Bussmann, Arjun Dey, C. Borys +6
We present SHARC-II 350um imaging of twelve 24um-bright (F_24um > 0.8 mJy) Dust-Obscured Galaxies (DOGs) and CARMA 1mm imaging of a subset of 2 DOGs, all selected from the Bootes f…
An Intensive HST Survey for z>1 Supernovae by Targeting Galaxy Clusters
K. S. Dawson, G. Aldering, R. Amanullah +57
We present a new survey strategy to discover and study high redshift Type Ia supernovae (SNe Ia) using the Hubble Space Telescope (HST). By targeting massive galaxy clusters at 0.9…
Active Galactic Nuclei and the Truncation of Star Formation in K+A Galaxies
Michael J. I. Brown, John Moustakas, Nelson Caldwell +7
We have searched for active galactic nuclei (AGNs) in K+A galaxies, using multiwavelength imaging and spectroscopy in the Bootes field of the NOAO Deep Wide-Field Survey. The K+A g…
The Discovery of a Large Lyman-alpha+HeII Nebula at z~1.67: A Candidate Low Metallicity Region?
M. K. M. Prescott, A. Dey, B. T. Jannuzi
We have discovered a ~45 kpc Lya nebula (or Lya ``blob'') at z~1.67 which exhibits strong, spatially-extended HeII emission and very weak CIV and CIII] emission. This is the first…
