2MASX J00423991+3017515: An offset active galactic nucleus in an interacting system
J. Drew Hogg, Laura Blecha, Christopher S. Reynolds +2
We present a spectroscopic and imaging study of an abnormal active galactic nucleus (AGN), 2MASX J00423991+3017515. This AGN is newly identified in the hard X-rays by the Swift BAT…
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…
A Statistical Study to Determine the Origin of Long-Duration Gamma-ray Flares
Lisa M. Winter, Valerie Bernstein, Nicola Omodei +1
Two scenarios have been proposed to account for sustained \,MeV gamma-ray emission in solar flares: (1) prolonged particle acceleration/trapping involving large-scale magne…
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…
Spectral Scaling Technique to Determine Extreme Carrington-level Geomagnetically Induced Currents Effects
Lisa M. Winter, Jennifer Gannon, Rick Pernak +6
Space weather events produce variations in the electric current in the Earth's magnetosphere and ionosphere. From these high altitude atmospheric regions, resulting geomagnetically…
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 (…
