The three-body problem from Newton to gravitational waves

Title: 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.

Group Meeting Talk: Current Algebras and Celestial CFT Correlators

Title: Current Algebras and Celestial CFT Correlators

Speaker: Sudip Ghosh

Abstract: I will discuss the construction of a SL(2,C) current algebra using the subleading soft graviton theorem and the constraints imposed by this current algebra via null state relations on the spectrum of the putative CFT dual of Einstein gravity in (3+1)-d asymptotically flat spacetimes.

Title: "A glimpse into the beauty of algebraic geometry (examples included!)"

Group Meeting Talk: Large N Phase Transitions and Small AdS-Schwarzschild Black Holes

Large N Phase Transitions and Small AdS-Schwarzschild Black Holes

Speaker: Sudip Ghosh

Abstract: We will discuss aspects of small AdS-Schwarzschild Black Holes in the context of the AdS/CFT correspondence. In particular we will consider issues related to dynamical instabilities of small black holes and their dual interpretation in the boundary gauge theory at large N.
