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).…
A SCUBA-2 850 micron survey of protoplanetary discs in the sigma Orionis cluster
Jonathan P. Williams, Lucas A. Cieza, Sean M. Andrews +8
We present the results from a large 850 micron survey of the sigma Orionis cluster using the SCUBA-2 camera on the James Clerk Maxwell Telescope. The 0.5-degree diameter circular r…
