### The three-body problem from Newton to gravitational waves

2020-09-14Title: The three-body problem from Newton to gravitational waves

Speaker: Dr. Alessandro Alberto Trani

Abstract:

The gravitational few-body problem is one of the oldest conundrums in astronomy and classical mechanics. Yet, its simplest instance, the three-body problem, has no general analytical solution and only a partial statistical solution has been achieved so far. With the birth of gravitational wave astronomy and the rise in exoplanet discoveries, the three-body problem is again becoming central to explaining astrophysical phenomena.

### Journal club seminar: More quantum noise from wormholes

2020-08-26**Title**: More quantum noise from wormholes

**Abstract**: We are going to discuss the nice paper by Douglas Stanford "More quantum noise from wormholes". Sudip Ghosh will lead the discussion.
