Resolving the cosmic X-ray background with a next-generation high-energy X-ray observatory

R. C. Hickox, F. Civano, D. R. Ballantyne +16

The cosmic X-ray background (CXB), which peaks at an energy of ~30 keV, is produced primarily by emission from accreting supermassive black holes (SMBHs). The CXB therefore serves…

Obscured AGNs in Bulgeless Hosts discovered by WISE: The Case Study of SDSS J1224+5555

S. Satyapal, N. J. Secrest, B. Rothberg +6

There is mounting evidence that supermassive black holes form and grow in bulgeless galaxies. However, a robust determination of the fraction of AGNs in bulgeless galaxies, an impo…

Variable Hard X-ray Emission from the Candidate Accreting Black Hole in Dwarf Galaxy Henize 2-10

Thomas J. Whalen, Ryan C. Hickox, Amy E. Reines +5

We present an analysis of the X-ray spectrum and long-term variability of the nearby dwarf starburst galaxy Henize 2-10. Recent observations suggest that this galaxy hosts an activ…

The clustering of H-alpha emitters at z=2.23 from HiZELS

J. E. Geach, D. Sobral, R. C. Hickox +5

(abridged) We present a clustering analysis of 370 high-confidence H-alpha emitters (HAEs) at z=2.23. The HAEs are detected in the Hi-Z Emission Line Survey (HiZELS), a large-area…

GOODS-Herschel: The far-infrared view of star formation in AGN host galaxies since z~3

J. R. Mullaney, M. Pannella, E. Daddi +28

We present a study of the infrared properties of X-ray selected, moderate luminosity (Lx=10^{42}-10^{44}ergs/s) active galactic nuclei (AGNs) up to z~3, to explore the links betwee…

Host galaxies, clustering, Eddington ratios, and evolution of radio, X-ray, and infrared-selected AGNs

Ryan C. Hickox, Christine Jones, William R. Forman +15

We explore the connection between different classes of active galactic nuclei (AGNs) and the evolution of their host galaxies, by deriving host galaxy properties, clustering, and E…
