X-ray Enhancement And Long-term Evolution Of Swift J1822.3-1606
Onur Benli, S. Caliskan, U. Ertan +3
We investigate the X-ray enhancement and the long-term evolution of the recently discovered, second "low-B magnetar" Swift J1822.3-1606 in the frame of the fallback disk model. Dur…
An accretion model for the anomalous X-ray pulsar 4U 0142+61
J. E. Truemper, K. Dennerl, N. D. Kylafis +2
We propose that the quiescent emission of AXPs/SGRs is powered by accretion from a fallback disk, requiring magnetic dipole fields in the range 10^{12}-10^{13} G, and that the lumi…
Discovery of an X-ray cavity near the radio lobes of Cygnus A indicating previous AGN activity
Gayoung Chon, Hans Boehringer, Martin Krause +1
Cygnus A harbours the nearest powerful radio jet of an Fanaroff-Riley (FR) class II radio galaxy in a galaxy cluster where the interaction of the jet with the intracluster medium (…
GRIPS - Gamma-Ray Imaging, Polarimetry and Spectroscopy
J. Greiner, K. Mannheim, F. Aharonian +65
We propose to perform a continuously scanning all-sky survey from 200 keV to 80 MeV achieving a sensitivity which is better by a factor of 40 or more compared to the previous missi…
The Energy Spectrum of Anomalous X-ray Pulsars and Soft Gamma-ray Repeaters
J. Trümper, A. Zezas, Ü. Ertan +1
Assuming that AXPs and SGRs accrete matter from a fallback disk, we attempt to explain both the soft and the hard X-ray emission as the result of the accretion process. We also att…
The Magnificent Seven in the dusty prairie -- The role of interstellar absorption on the observed neutron star population
B. Posselt, S. B. Popov, F. Haberl +3
The Magnificent Seven have all been discovered by their exceptional soft X-ray spectra and high ratios of X-ray to optical flux. They all are considered to be nearby sources. Searc…
