Detection of Gamma Rays From a Starburst Galaxy
The HESS Collaboration, F. Acero
Starburst galaxies exhibit in their central regions a highly increased rate of supernovae, the remnants of which are thought to accelerate energetic cosmic rays up to energies of ~…
Slim disks around Kerr black holes revisited
Aleksander Sadowski
We investigate stationary slim accretion disks around Kerr black holes. We construct a new numerical method based on the relaxation technique. We systematically cover the whole par…
The relativistic entrainment matrix of a superfluid nucleon-hyperon mixture at zero temperature
M. E. Gusakov, E. M. Kantor, P. Haensel
We calculate the relativistic entrainment matrix Y_ik at zero temperature for nucleon-hyperon mixture composed of neutrons, protons, Lambda and Sigma^- hyperons, as well as of elec…
Simultaneous observations of PKS 2155-304 with H.E.S.S., Fermi, RXTE and ATOM: spectral energy distributions and variability in a low state
H. E. S. S., Fermi-LAT collaborations
We report on the first simultaneous observations that cover the optical, X-ray, and high energy gamma-ray bands of the BL Lac object PKS 2155-304. The gamma-ray bands were observed…
Compton reflection in AGN with Simbol-X
V. Beckmann, T. J. -L. Courvoisier, N. Gehrels +5
AGN exhibit complex hard X-ray spectra. Our current understanding is that the emission is dominated by inverse Compton processes which take place in the corona above the accretion…
H.E.S.S. observations of gamma-ray bursts in 2003-2007
F. Aharonian
Very-high-energy (VHE; >~100 GeV) gamma-rays are expected from gamma-ray bursts (GRBs) in some scenarios. Exploring this photon energy regime is necessary for understanding the ene…
