A hard look at NGC 5347: revealing a nearby Compton-thick AGN
E. S. Kammoun, J. M. Miller, A. Zoghbi +11
Current measurements show that the observed fraction of Compton-thick (CT) AGN is smaller than the expected values needed to explain the cosmic X-ray background. Prior fits to the…
The Advanced X-ray Imaging Satellite
Richard F. Mushotzky, James Aird, Amy J. Barger +41
Much of the baryonic matter in the Universe, including the most active and luminous sources, are best studied in the X-ray band. Key advances in X-ray optics and detectors have pav…
NuSTAR and Keck Observations of Heavily Obscured Quasars Selected by WISE
Wei Yan, Ryan C. Hickox, Kevin N. Hainline +15
A primary aim of the Nuclear Spectroscopic Telescope Array (NuSTAR) mission is to find and characterize heavily obscured Active Galactic Nuclei (AGNs). Based on mid-infrared photom…
Active galactic nuclei flicker: an observational estimate of the duration of black hole growth phases of ~1e5 years
Kevin Schawinski, Michael Koss, Simon Berney +1
We present an observational constraint for the typical active galactic nucleus (AGN) phase lifetime. The argument is based on the time lag between an AGN central engine switching o…
A comparison of the morphological properties between local and z~1 infrared luminous galaxies. Are local and high-z (U)LIRGs different?
Chao-Ling Hung, D. B. Sanders, Caitlin M. Casey +9
Ultraluminous and luminous infrared galaxies (ULIRGs and LIRGs) are the most extreme star-forming galaxies in the universe, and dominate the total star formation rate density at z>…
NuSTAR and XMM-Newton Observations of Luminous, Heavily Obscured, WISE-Selected Quasars at z ~ 2
D. Stern, G. B. Lansbury, R. J. Assef +30
We report on a NuSTAR and XMM-Newton program that has observed a sample of three extremely luminous, heavily obscured WISE-selected AGN at z~2 in a broad X-ray band (0.1 - 79 keV).…
