Hard X-ray properties of radio-selected blazars
Marcus Langejahn, Matthias Kadler, Jörn Wilms +6
Hard X-ray properties of beamed AGN have been published in the 105-month Swift/BAT catalog, but there have not been any studies carried out so far on a well-defined, radio-selected…
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…
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…
The 70 Month Swift-BAT All-Sky Hard X-Ray Survey
W. H. Baumgartner, J. Tueller, C. B. Markwardt +5
We present the catalog of sources detected in 70 months of observations of the BAT hard X-ray detector on the Swift gamma-ray burst observatory. The Swift-BAT 70 month survey has d…
The Simultaneous Low State Spectral Energy Distribution of 1ES 2344+514 from Radio to Very High Energies
MAGIC Collaboration, J. Aleksić, L. A. Antonelli +191
[Abridged] Context. To construct and interpret the spectral energy distribution (SED) of BL Lacertae objects, simultaneous broad-band observations are mandatory. Aims. We present t…
The Hard X-ray Polarimeter X-Calibur - Design and Tests
M. Beilicke, W. R. Binns, J. Buckley +17
X-ray polarimetry promises to give new information about high-energy astrophysical sources, such as binary black hole systems, micro-quasars, active galactic nuclei, and gamma-ray…
