Astronomy Colloquium: Yohai Meiron

Yohai Meiron from the Kavli Institute for Astronomy and Astrophysics at Peking University in China will be the featured speaker at a Department of Physics and Astronomy Colloquium. His talk is titled, "Stellar kinematic signature of massive black hole binaries."

He will present a novel way to detect the current and past presence of massive black hole binaries in galactic centers. The inspiral of the two black holes from galactic scale up to the formation of a bound pair induces a unique kinematic fingerprint: an inner stellar core counter-rotating with respect to the binary's orbital motion, followed by a co-rotating population at larger scales.
