Study of the synchrotron and inverse Compton radiations of relativistic jets in GRS 1915+105

Comparison of the detailed calculations of the synchrotron radiation of expanding magnetized clouds with the temporal and spectral evolution of radio flares observed from the recently discovered galactic microquasar GRS 1915+105 imposes strong constraints on the model parameters of relativistic plasmoids. The data of radio monitoring of the pair of ejecta not only enable unambiguous determination of the aspect angle and the speeds of propagation of both components, but also contain an important information about the energy source for acceleration of the electrons, in particular, may distinguish between the scenarios of bow-shock powered and magnetized relativistic wind powered plasmoids. Within the framework of the synchrotron self Compton model we calculate the fluxes of synchrotron hard X-rays and GeV/TeV inverse Compton gamma-rays, and discuss constraints on the parameters of GRS 1915+105 which could be provided by positive detection or flux upper limits of these energetic photons.
