BAT AGN Spectroscopic Survey I: Spectral Measurements, Derived Quantities, and AGN Demographics
Michael Koss, Benny Trakhtenbrot, Claudio Ricci +20
We present the first catalog and data release of the Swift-BAT AGN Spectroscopic Survey (BASS). We analyze optical spectra of the majority of AGN (77%, 641/836) detected based on t…
Spitzer IRAC observations of IR excess in Holmberg IX X-1: A circumbinary disk or a variable jet?
R. P. Dudik, C. T. Berghea, T. P. Roberts +4
We present Spitzer Infrared Array Camera (IRAC) photometric observations of the Ultra-luminous X-ray Source (ULX, X-1) in Holmberg IX. We construct a spectral energy distribution (…
The Local Environment of Ultraluminous X-ray Sources Viewed by XMM Newton's Optical Monitor
Ciprian T. Berghea, Rachel P. Dudik, Jonathan Tincher +1
We have used XMM-Newton's Optical Monitor (OM) images to study the local environment of a sample of 27 Ultraluminous X-ray Sources (ULXs) in nearby galaxies. UVW1 fluxes were extra…
Multiwavelength Observations of Swift J1753.5-0127
C. S. Froning, T. J. Maccarone, K. France +4
We present contemporaneous X-ray, ultraviolet, optical and near-infrared observations of the black hole binary system, Swift J1753.5-0127, acquired in 2012 October. The UV observat…
Three AGN Close To The Effective Eddington Limit
R. V. Vasudevan, A. C. Fabian, R. F. Mushotzky +3
The Effective Eddington Limit for dusty gas surrounding AGN is lower than the canonical Eddington limit for hydrogen gas. Previous results from the Swift/BAT 9-month catalogue sugg…
X-ray properties of the Northern Galactic Cap AGNs in the 58-month Swift-BAT catalog
Ranjan V. Vasudevan, William N. Brandt, Richard F. Mushotzky +5
We present a detailed X-ray spectral analysis of a complete sample of hard X-ray selected AGN in the Northern Galactic Cap of the 58-month Swift Burst Alert Telescope (Swift/BAT) c…
