CG: Virtual Workshop – Gravitational Waves – Vieira Gomes
April 21 @ 5:00 pm – 6:30 pm CMT
Gravitational waves are solutions of General Relativity (GR) both at linear and fully nonlinear levels, and have been directly found recently. These can be addressed from different approaches: linearisation for far field solutions, numerical relativity to grasp the neighbouring of the source, Newman-Penrose formalism built upon the tetrad formulation of GR, among others. This workshop aims at giving an introduction to these solutions in GR and in alternative theories of gravity either from linearisation or Newman-Penrose methods. We shall also discuss some caveats in these scenarios when matter fields are present.
