The z=5 Quasar Luminosity Function from SDSS Stripe 82

Ian D. McGreer, Linhua Jiang, Xiaohui Fan +12

We present a measurement of the Type I quasar luminosity function at z=5 using a large sample of spectroscopically confirmed quasars selected from optical imaging data. We measure…

Moderate-Luminosity Growing Black Holes From 1.25 < z < 2.7: Varied Accretion In Disk-Dominated Hosts

Brooke D. Simmons, C. Megan Urry, Kevin Schawinski +2

We compute black hole masses and bolometric luminosities for 57 active galactic nuclei (AGN) in the redshift range 1.25 < z < 2.67, selected from the GOODS-South deep multi-wavelen…

Finding Rare AGN: X-ray Number Counts of Chandra Sources in Stripe 82

Stephanie M. LaMassa, C. Megan Urry, Eilat Glikman +14

We present the first results of a wide area X-ray survey within the Sloan Digital Sky Survey (SDSS) Stripe 82, a 300 deg region of the sky with a substantial investment in mult…

Spitzer Observations of Young Red Quasars

Tanya Urrutia, Mark Lacy, Henrik Spoon +3

We present mid-infrared spectra and photometry of thirteen redshift 0.4<z<1 dust-reddened quasars obtained with Spitzer IRS and MIPS. We compare properties derived from their infra…

FIRST-2MASS Red Quasars: Transitional Objects Emerging from the Dust

Eilat Glikman, Tanya Urrutia, Mark Lacy +8

We present a sample of 120 dust-reddened quasars identified by matching radio sources detected at 1.4 GHz in the FIRST survey with the near-infrared 2MASS catalog and color-selecti…

Heavily Obscured Quasar Host Galaxies at z~2 are Disks, Not Major Mergers

Kevin Schawinski, Brooke D. Simmons, Megan Urry +2

We explore the nature of heavily obscured quasar host galaxies at z~2 using deep Hubble Space Telescope WFC3/IR imaging of 28 Dust Obscured Galaxies (DOGs) to investigate the role…
