The Amazing X-ray Binary GRS 1915+105 Dr. Andrea Martocchia (Observatoire Astronomique, Strasbourg)
GRS 1915+105 is a well-studied X-ray binary and a "microquasar" showing radio jets with apparent superluminal velocities. New results will be summarized, giving particular emphasis to the data recently collected by X- and gamma-ray satellites. The estimates of the compact object mass as well as some properties of the source X-ray spectrum indicate that a black hole is hosted in the core. However, detailed modelling of its variability, spectral features and accretion/ejection phenomena is a non-trivial task that leaves us with open questions.
