Recent Observations of Gravitational Waves by LIGO and Virgo Detectors

In this paper we present the most recent observations of gravitational waves (GWs) by LIGO and Virgo detectors. We also discuss contributions of the recent Nobel prize winner, Sir Roger Penrose to understanding gravitational radiation and black holes …

Approach of background metric expansion to a new metric ansatz for gauged and ungauged Kaluza-Klein supergravity black holes

Novel background metric expansion method for constructing rotating charged black hole solutions in higher-dimensional Kaluza-Klein supergravity with (anti-)de Sitter spacetime.
