Abdelghani Errehymy

About

My research focuses on general relativity and extended theories of gravity, particularly their applications to high-energy astrophysical phenomena. My interests include the physics of compact objects (neutron stars, wormholes, and black holes), as well as analytical and numerical methods, and gravitational waves.
