[OBSCURA] The Milky Way's 19 black holes

Eric Betz's D-Brief blog post "Prepare for an Explosion of Gravitational Wave Detections", examining the exciting possibility of imminent gravitational wave observations giving us unprecedented insight into black holes, included this map of the Milky Way Galaxy's known 19 black holes. This graphic, by Astronomy's Roen Kelly, originally featured in Richard Talcott's February 2016 article "A guide to the black holes in our backyard". There are surely many more than 19, but these are all we know for now. Perhaps LIGO will let us track down some more?
