Gr@v members A. Morais, M. Finetti, J. Gonçalves and V. Oliveira visited CERN between the 13th and 16th May to participate in the 4th anual EuCAPT symposium, with the presentation of three posters and a lightning talk by M. Finetti.
GW170817 and GRB 170817A provided direct evidence that binary neutron star (NSNS) mergers can produce short gamma-ray bursts (sGRBs). However, questions remain about the nature of the central engine.
Galaxy clusters are excellent natural laboratories to study the nature of gravity and test possible alternatives to the Concordance Model, at the edge between cosmology and astrophysics.
P. Cunha and C. Herdeiro were invited speakers at the online workshop on numerical and analytical relativity (NAR-2024), organized by the Department of Applied Sciences, Indian Institute of Information Technology Allahabad (IIITA) during 20 - 22 March 2024. The video recorded lectures can be seen here.
Numerical Relativity is a key tool for the study of strong-field gravity. I will present a new evolution code, based on the Kadath library. It relies on multidomain spectral methods for the space discretization, and explicit time integration schemes.
