Stochastic Gravitational Wave Background from Exoplanets
Anirban Ain, Shilpa Kastha, Sanjit Mitra
Recent exoplanet surveys have predicted a very large population of planetary systems in our galaxy, more than one planet per star on the average, perhaps totalling about two hundre…
Gravitational Lensing by Self-Dual Black Holes in Loop Quantum Gravity
Satyabrata Sahu, Kinjalk Lochan, D. Narasimha
We study gravitational lensing by a recently proposed black hole solution in Loop Quantum Gravity. We highlight the fact that the quantum gravity corrections to the Schwarzschild m…
Timescale for trans-Planckian collisions in Kerr spacetime
Mandar Patil, Pankaj S. Joshi, Ken-ichi Nakao +2
We make a critical comparison between ultra-high energy particle collisions around an extremal Kerr black hole and that around an over-spinning Kerr singularity, mainly focusing on…
A quantum peek inside the black hole event horizon
Sumanta Chakraborty, Suprit Singh, T. Padmanabhan
We solve the Klein-Gordon equation for a scalar field, in the background geometry of a dust cloud collapsing to form a black hole, everywhere in the (1+1) spacetime: that is, both…
