Deriving effective descriptions and signal predictions for dynamical gravitational systems
Steven B. Giddings, Madhur Mehta
We investigate top-down derivations of effective descriptions for radiation from gravitational systems such as binaries. With a specified cutoff prescription, one can derive worldl…

Extreme Compactness, Extreme Gravity: Higher-Derivative Corrections to ECOs
Madhur Mehta
Higher-derivative gravity theories offer insights into the behavior of extremely compact objects (ECOs). Focusing on Gauss-Bonnet (GB) and Einstein-dilaton-Gauss-Bonnet (EdGB) grav…

The Fuzzball Paradigm
Samir D. Mathur, Madhur Mehta
We describe the puzzles that arise in the quantum theory of black holes, and explain how they are resolved in string theory. We review how the Bekenstein entropy is obtained throug…
