Overview

Abstract

Using the Very Long Baseline Array, we have measured a trigonometric parallax for the microquasar GRS 1915 105, which contains a black hole and a K-giant companion. This yields a direct distance estimate of 8.6^2.0_{-1.6} kpc and a revised estimate for the mass of the black hole of 12.4^2.0_-1.8 M _☉. GRS 1915 105 is at about the same distance as some H
