Vanishing hardness-flux correlation in Cygnus X-1: signs of the disc moving out
M. Axelsson, L. Hjalmarsdotter, L. Borgonovo +1
Aims. We investigate observations of the X-ray binary Cygnus X-1 with unusually high hardness and low flux. In particular, we study the characteristic frequencies seen in the PDS a…
Hyper-accreting tori of Gamma Ray Bursters
M. V. Barkov
We present numerical simulations of axisymmetric magnetised massive tori around rotating black holes taking into account the energy losses due to emission of neutrinos. A realistic…
PoGOLite - A High Sensitivity Balloon-Borne Soft Gamma-ray Polarimeter
Tuneyoshi Kamae, Viktor Andersson, Makoto Arimoto +36
We describe a new balloon-borne instrument (PoGOLite) capable of detecting 10% polarisation from 200mCrab point-like sources between 25 and 80keV in one 6 hour flight. Polarisation…
Measuring energy dependent polarization in soft gamma-rays using Compton scattering in PoGOLite
M. Axelsson, O. Engdegård, F. Ryde +23
Linear polarization in X- and gamma-rays is an important diagnostic of many astrophysical sources, foremost giving information about their geometry, magnetic fields, and radiation…
