X-ray hiccups from SgrA* observed by XMM-Newton. The second brightest flare and three moderate flares caught in half a day
D. Porquet, N. Grosso, P. Predehl +14
[truncated] In Spring 2007, we observed SgrA* with XMM with a total exposure of ~230ks. We have performed timing and spectral analysis of the new X-ray flares detected during this…
Modulated X-ray Emissivity near the Stress Edge in Sgr A*
M. Falanga, F. Melia, M. Prescher +2
Sgr A* is thought to be the radiative manifestation of a ~3.6E6 Msun supermassive black hole at the Galactic center. Its mm/sub-mm spectrum and its flare emission at IR and X-ray w…
Intermediate long X-ray bursts from the ultra-compact binary source SLX 1737-282
M. Falanga, J. Chenevez, A. Cumming +3
Aims: The low persistent X-ray burster source SLX 1737-282 is classified as an ultra-compact binary candidate. We compare the data on SLX 1737-282 with the other similar objects an…
High Energy Activity of the Super-Massive Black Hole at the Galactic Center
Andrea Goldwurm
The centre of our galaxy hosts the nearest super-massive black hole to the solar system, identified to the compact radio source Sgr A*. High energy experiments have tried in the pa…
General Relativistic Flux Modulations from Disk Instabilities in Sagittarius A*
Maurizio Falanga, Fulvio Melia, Michel Tagger +2
Near-IR and X-ray flares have been detected from the supermassive black hole Sgr A* at the center of our Galaxy with a (quasi)-period of ~17-20 minutes, suggesting an emission regi…
Broad-band spectral changes of the microquasars Cygnus X-1 and SWIFT J1753.5-0127
Marion Cadolle Bel, Marc Ribo, Jerome Rodriguez +3
We report high-energy results obtained with INTEGRAL and Rossi-XTE on two microquasars: the persistent high-mass system Cygnus X-1 and the transient low-mass binary SWIFT J1753.5-0…
