The Distribution of AGN Covering Factors
Andy Lawrence, Isaac Roseboom, Jack Mayo +4
We review our knowledge of the most basic properties of the AGN obscuring region - its location, scale, symmetry, and mean covering factor - and discuss new evidence on the distrib…
A massive proto-cluster of galaxies at a redshift of z {\approx} 5.3
Peter L. Capak, Dominik Riechers, Nick Z. Scoville +14
Massive clusters of galaxies have been found as early as 3.9 Billion years (z=1.62) after the Big Bang containing stars that formed at even earlier epochs. Cosmological simulations…
Observational Limits on Type 1 AGN Accretion Rate in COSMOS
Jonathan R. Trump, Chris D. Impey, Brandon C. Kelly +13
We present black hole masses and accretion rates for 182 Type 1 AGN in COSMOS. We estimate masses using the scaling relations for the broad Hb, MgII, and CIV emission lines in the…
The Chandra COSMOS Survey, I: Overview and Point Source Catalog
Martin Elvis, Francesca Civano, Cristian Vignali +40
The Chandra COSMOS Survey (C-COSMOS) is a large, 1.8 Ms, Chandra} program that has imaged the central 0.5 sq.deg of the COSMOS field (centered at 10h, +02deg) with an effective exp…
Stellar and total baryon mass fractions in groups and clusters since redshift 1
S. Giodini, D. Pierini, A. Finoguenov +24
We investigate if the discrepancy between estimates of the total baryon mass fraction obtained from observations of the cosmic microwave background (CMB) and of galaxy groups/clust…
Understanding the Astrophysics of Galaxy Evolution: the role of spectroscopic surveys in the next decade
Eric Bell, Marc Davis, Arjun Dey +24
Over the last decade optical spectroscopic surveys have characterized the low redshift galaxy population and uncovered populations of star-forming galaxies back to z ~ 7. This work…
