Long-term variability of AGN at hard X-rays
S. Soldi, V. Beckmann, W. H. Baumgartner +6
Variability at all observed wavelengths is a distinctive property of AGN. Hard X-rays provide us with a view of the innermost regions of AGN, mostly unbiased by absorption along th…
Reflection-dominated nuclear X-ray emission in the early-type galaxy ESO 565--G019
P. Gandhi, Y. Terashima, S. Yamada +8
We present the discovery of a reflection-dominated active galactic nucleus (AGN) in the early-type radio-quiet galaxy ESO 565--G019 with Suzaku and Swift/BAT. The source X-ray spec…
White Paper for Blazar Observations with a GEMS-like X-ray Polarimetry Mission
Henric Krawczynski, Lorella Angelini, Matthew Baring +27
In this document, we describe the scientific potential of blazar observations with a X-ray polarimetry mission like GEMS (Gravity and Extreme Magnetism SMEX). We describe five blaz…
Kepler observations of rapid optical variability in the BL Lac object W2R1926+42
R. Edelson, R. Mushotzky, S. Vaughan +4
We present the first Kepler monitoring of a strongly variable BL Lac, W2R1926+42. The light curve covers 181 days with ~0.2% errors, 30 minute sampling and >90% duty cycle, showing…
White Paper on GEMS Study of Polarized X-rays from Neutron Stars
Pranab Ghosh, Lorella Angelini, Matthew Baring +27
We examine the expected X-ray polarization properties of neutron-star X-ray sources of various types, e.g., accretion and rotation powered pulsars, magnetars, and low-mass X-ray bi…
Studying Faint Ultra Hard X-ray Emission from AGN in GOALS LIRGs with Swift BAT
Michael Koss, Richard Mushotzky, Wayne Baumgartner +4
We present the first analysis of the all-sky Swift BAT ultra hard X-ray (14-195 keV) data for a targeted list of objects. We find the BAT data can be studied at 3x fainter limits t…
