Spectral energy distribution, radio maps and polarization of Cygnus X-1: a lepto-hadronic model

Romero, G. E.; Vila, G. S.; Pepe, C.

The microquasar Cygnus X-1 is one of the most studied astrophysical sources. Several radiative models for the non-thermal broadband emission of Cygnus X-1 are available. For the jet emission in particular, only leptonic models have been considered despite the observational evidence of the presence of hadrons in the jets of other microquasars. In t…

The cosmic history of black hole growth

Treister, E.

Significant progress has been made in the last few years in our understand- ing of how and when supermassive black holes form and grow. Here, I review our current knowledge of the cosmic evolution of the population of Active Galactic Nuclei (AGN), which hosts most of the supermassive black hole growth. Thanks to deep multiwavelength surveys it has…

New Gamma Ray sources discovered by INTEGRAL

Combi, J. A.

One of the strategic objective of the INTEGRAL mission is a regular survey of the galactic plane complemented by a deep exposure of the Galactic Centre. This study is carrying out by the imaging capability of IBIS, which allows the detection of sources at the mCrab level with an angular resolution of 12 arcmin and a point souce location accuracy o…
