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 accreting blacks holes across the mass scale. 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 re-analysis of archival VLT data shows that this mass estimate is likely subject to significant systematic uncertainty. We propose new observations, which will lead to a reliable mass estimate for the black hole in this system.
