Series: Astronomy Colloquium
Date: Wednesday 14-Nov-2018
Time: 16:05-17:00 (4:05-5:00 pm)
Location: ATL 2400
Speaker: Dr. Yuri Levin (Flatiron Institute New York)
Title: Fun with black holes.
Gravitational wave observations finally give us firm evidence that god is playing billiards with black holes. I will discuss a couple of interesting BH-related phenomena that one might look for in the GW sky. Firstly, I will discuss GW memory, which is potentially detectable by LISA (very likely), LIGO (if we are patient), and Pulsar Timing Arrays (if we and our descendants are patient). Secondly I will discuss vibrating nets of black holes connected by cosmic strings, physically interesting objects that may arise in the early Universe if both cosmic strings and primordial BHs are present. A possible third fun thing might also be discussed.
Colloquia are usually preceded by espresso and ice cream at 1:45 pm outside room PSC 1150 and are followed by an informal reception at 5:15 pm in that room. Anyone interested in talking with the speaker, or being added to the colloquium announcement email list, should contact the colloquium organizer. Lunch will normally be reserved for the speaker to talk to graduate students.
