10. Multimessenger Lensing in Black Hole Spacetimes: Light, High-Frequency Gravitational Waves, and Massive Particles

Dr Torben Christian Frost (Kavli Institute for Astronomy and Astrophysics, Peking University)

8/6/24, 2:00 PM

Black holes are some of the most interesting objects in astrophysics. Light, gravitational waves, and massive particles emitted or passing in their close vicinity are gravitationally lensed and provide a unique probe of gravity in the strong field regime. On one hand this allows to test different black hole models from general relativity or alternative theories of gravity, and on the other...

11. Accelerating BTZ black holes

Dr Aaron Poole (Kyung Hee University)

8/6/24, 2:30 PM

In this talk I will review the construction of the three dimensional "accelerating BTZ" black hole solution and contrast this with the well known "C-metric" in four spacetime dimensions. I will then discuss how the presence of acceleration affects the variational problem, thermodynamic aspects and holographic interpretation via AdS/CFT. This talk is based on ongoing work with Euihun Joung,...

12. Rotating Black Holes in a Lorentz Violating Gravity: Finding Exact Solutions Without Tears

Dr Mu-In Park (CQUeST)

8/6/24, 3:00 PM

We consider how to find exact solutions for rotating black holes in a four-dimensional Lorentz violating gravity and its interesting physical properties which are quite different from the Kerr solution in GR.

30. Black Holes from Young Diagrams

Prof. Minkyoo Kim (CQUeST)

8/8/24, 3:00 PM

We study heavy operators of N=4 SYM. Because they have dimensions over the order of N, their correlation functions, etc., are not sufficient as planar contributions even in the large N limit, and nonplanar effects are important. In particular, we would like to propose a holographic dual of a black hole from heavy operators with a dimension of order N^2. These are constructed from restricted...
