The runaway instability of thick discs around black holes. II. Non constant angular momentum discs
Frederic Daigne, Jose A. Font
We present results from a comprehensive number of relativistic, time-dependent, axisymmetric simulations of the runaway instability of non-constant angular momentum thick discs aro…
The X-ray flaring activity of the galactic nucleus observed with XMM-Newton
E. Brion, A. Goldwurm, P. Goldoni +3
We report the results of XMM-Newton observations of Sgr A*, the radiative counterpart of the massive black hole at the nucleus of our Galaxy, performed in the frame of the guarante…
A New X-Ray Flare from the Galactic Nucleus Detected with the XMM-Newton
A. Goldwurm, E. Brion, P. Goldoni +5
The compact radio source Sgr A*, believed to be the counterpart of the massive black hole at the Galactic nucleus, was observed to undergo rapid and intense flaring activity in X-r…
On the nature of X-ray Flashes
Robert Mochkovitch, Frederic Daigne, Celine Barraud +1
We have developed a toy model for internal shocks which has been used to generate a large number of synthetic GRBs in order to find in the parameter space the conditions which can…
The physics of pulses in gamma-ray bursts: emission processes, temporal profiles and time lags
Frederic Daigne, Robert Mochkovitch
We present a simple, semi-analytical model to explain GRB temporal and spectral properties in the context of the internal shock model. Each individual pulse in the temporal profile…
