HESS upper limits on very high energy gamma-ray emission from the microquasar GRS 1915 105

Original language description

High energy particles reside in the relativistic jets of microquasars, making them possible sources of very high energy radiation (VHE, }100 GeV). Detecting this emission would provide a new handle on jet physics.The VHE to X-ray luminosity ratio in GRS1915 105 is at least four orders of magnitude lower than the ratio observed in gamma-ray binaries. The VHE radiative efficiency of the compact jet is less than 0.01% based on its estimated total power of 1038 erg-s-1. Particle acceleration in GRS 1915 105 is not efficient at high energies and/or the magnetic field is too strong. It is also possible that VHE gamma-rays are produced by GRS 1915 105, but the emission is highly time-dependent.
