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.

C. Herdeiro was one of the plenary invited speakers of the International Conference on Gravitation and Cosmology (ICGC 24) and the International Conference on Relativistic Astrophysics and Cosmology (ICRAC 24) that took place in Lahore, Pakistan on 29-31 Jan and 1-2 Feb 2024. Wonderful hospitality and great interactions. Science brings people together.
The prospect of a stochastic gravitational wave (GW) background from the primordial universe offers a promising new window for cosmology and fundamental physics.
