Title: The Mass of the Black Hole in the Galactic Microquasar GRS 1915+105
Abstract:
Probing General Relativity in the strong field regime and
understanding the production of relativistic jets are two critical
issues in the study of X-ray binaries. In both of these areas the
Galactic microquasar GRS 1915+105 occupies a unique place in our effort
to address these questions: in addition, it is nominally the most
massive of all known stellar-mass Galactic black holes. However, a
reanalysis of archival VLT data shows that this mass estimate is likely
subject to significant systematic uncertainty. We propose new
observations, which should lead to a more reliable mass estimate for the
black hole in this system.
