The Chandra COSMOS Legacy survey: optical/IR identifications
S. Marchesi, F. Civano, M. Elvis +27
We present the catalog of optical and infrared counterparts of the Chandra COSMOS-Legacy Survey, a 4.6 Ms Chandra program on the 2.2 square degrees of the COSMOS field, combination…
Faint COSMOS AGN at z~3.3 - I. Black Hole Properties and Constraints on Early Black Hole Growth
Benny Trakhtenbrot, Francesca Civano, C. Megan Urry +9
We present new Keck/MOSFIRE K-band spectroscopy for a sample of 14 faint, X-ray-selected active galactic nuclei (AGNs) in the COSMOS field. The data cover the spectral region surro…

We release the next installment of the Stripe 82 X-ray survey point-source catalog, which currently covers 31.3 deg of the Sloan Digital Sky Survey (SDSS) Stripe 82 Legacy fiel…
A population of intermediate-mass black holes in dwarf starburst galaxies up to redshift=1.5
M. Mezcua, F. Civano, G. Fabbiano +2
We study a sample of 50,000 dwarf starburst and late-type galaxies drawn from the COSMOS survey with the aim of investigating the presence of nuclear accreting black holes (B…
