Description
The microquasar GRS 1915+105 features well known spectral states that were never extensively studied up to the MeV range, where key spectral diagnostics are expected. We present hard X-ray observations obtained in 15 Msec with Swift/BAT and INTEGRAL and spectra collected during different states up to 400 keV. These spectra can be successfully fitted by the EQPAIR model revealing continuous variations of the model parameters, including the inner radius of the accretion disc, along the sequence of spectral states.
