Warren Brown (Smithsonian Astrophysical Observatory)
A massive black hole sits in the heart of the Milky Way. One consequence of the black hole is that it ejects "hypervelocity stars" from the Milky Way at ~1000 km/s velocities. We discovered the first hypervelocity star in 2005, and since then our t ...
