Optical Selection of Faint AGN in the COSMOS Field
C. M. Casey, C. D. Impey, J. R. Trump +6
We outline a strategy to select faint (i<24.5) type 1 AGN candidates down to the Seyfert/QSO boundary for spectroscopic targeting in the COSMOS field, picking candidates by their n…
Observational Constraints on the Dependence of Radio-Quiet Quasar X-ray Emission on Black Hole Mass and Accretion Rate
Brandon C. Kelly, Jill Bechtold, Jonathan R. Trump +2
In this work we use a sample of 318 radio-quiet quasars (RQQ) to investigate the dependence of the ratio of optical/UV flux to X-ray flux, alpha_ox, and the X-ray photon index, Gam…
Magellan Spectroscopy of AGN Candidates in the COSMOS Field
Jonathan R. Trump, Chris D. Impey, Patrick J. McCarthy +8
We present spectroscopic redshifts for the first 466 X-ray and radio-selected AGN targets in the 2 deg^2 COSMOS field. Spectra were obtained with the IMACS instrument on the Magell…
The Sloan Digital Sky Survey Quasar Catalog II. First Data Release
Donald P. Schneider, Xiaohui Fan, Patrick B. Hall +13
We present the second edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog consists of 16713 objects in the SDSS First Data Release (DR1) that have luminositi…
