NuSTAR and XMM-Newton Observations of the Hard X-Ray Spectrum of Centaurus A
F. Fuerst, C. Mueller, K. K. Madsen +28
We present simultaneous XMM-Newton and NuSTAR observations spanning 3-78 keV of the nearest radio galaxy, Centaurus A (Cen A). The accretion geometry around the central engine in C…
Optical-NIR spectroscopy of the puzzling gamma-ray source 3FGL 1603.9-4903/PMN J1603-4904 with X-shooter
P. Goldoni, S. Pita, C. Boisson +6
The Fermi/LAT instrument has detected about two thousands Extragalactic High Energy (E > 100 MeV) gamma-ray sources. One of the brightest is 3FGL 1603.9-4903, associated to the rad…
Black Hole Lightning from the Peculiar Gamma-Ray Loud Active Galactic Nucleus IC 310
Dorit Eisenacher Glawion, Julian Sitarek, Karl Mannheim +7
The nearby active galaxy IC 310, located in the outskirts of the Perseus cluster of galaxies is a bright and variable multi-wavelength emitter from the radio regime up to very high…
A Variable-Density Absorption Event in NGC 3227 mapped with Suzaku and Swift
T. Beuchert, A. G. Markowitz, F. Krauß +15
The morphology of the circumnuclear gas accreting onto supermassive black holes in Seyfert galaxies remains a topic of much debate. As the innermost regions of Active Galactic Nucl…
PSR J1906+0722: An Elusive Gamma-ray Pulsar
C. J. Clark, H. J. Pletsch, J. Wu +117
We report the discovery of PSR J1906+0722, a gamma-ray pulsar detected as part of a blind survey of unidentified Fermi Large Area Telescope (LAT) sources being carried out on the v…
TANAMI counterparts to IceCube high-energy neutrino events
Felicia Krauß, Bingjie Wang, Claire Baxter +8
Since the discovery of a neutrino flux in excess of the atmospheric background by the IceCube Collaboration, searches for the astrophysical sources have been ongoing. Due to the st…
Insights into the particle acceleration of a peculiar gamma -ray radio galaxy IC 310
J. Sitarek, D. Eisenacher Glawion, K. Mannheim +7
IC 310 has recently been identified as a gamma-ray emitter based on observations at GeV energies with Fermi-LAT and at very high energies (VHE, E > 100 GeV) with the MAGIC telescop…
A redshifted Fe K line from the unusual gamma-ray source PMN J1603-4904
C. Müller, F. Krauß, T. Dauser +12
Multiwavelength observations have revealed the highly unusual properties of the gamma-ray source PMN J1603-4904, which are difficult to reconcile with any other well established ga…
