Signature of Non-uniform Area Quantization on Gravitational Waves
Kabir Chakravarti, Rajes Ghosh, Sudipta Sarkar
Quantum aspects of black holes may have observational imprints on their absorption and emission spectrum. In this work, we consider the possibility of non-uniform area quantization…
Causality constraints in Quadratic Gravity
Jose D. Edelstein, Rajes Ghosh, Alok Laddha +1
Classifying consistent effective field theories for the gravitational interaction has recently been the subject of intense research. Demanding the absence of causality violation in…
Light rings of stationary spacetimes
Rajes Ghosh, Sudipta Sarkar
We present a novel theorem regarding light rings in a stationary spacetime with an ergoregion. We prove that any stationary, axisymmetric, and asymptotically flat spacetime in 1 +…
Black Hole Zeroth Law in Higher Curvature Gravity
Rajes Ghosh, Sudipta Sarkar
The zeroth law of black hole mechanics is an assertion of constancy of the surface gravity on a stationary Killing horizon. The Hawking temperature of the black hole horizon is pro…
Overcharging higher curvature black holes
Rajes Ghosh, C. Fairoos, Sudipta Sarkar
We examine the problem of overcharging extremal and near-extremal black hole solutions of Einstein-Gauss-Bonnet gravity in any dimension, generalizing the result in general relativ…
