It is widely believed that the fast rotation of a massive star affects the dynamics of core-collapse and eventually results in the most luminous event in the present universe, the long gamma-ray burst (LGRB). Another important consequence of the fast rotation would be an energetic supernova explosion, which is often observed to be associated with LGRBs.
Stellar Compact object mergers are not only important sources of gravitational waves but also central engines that power electromagnetic transients and r-processes, if matter is involved. I will review recent progress modeling the merger of black hole-neutron star and neutron stars binaries highlighting state-of-the-art general relativistic hydrodynamic simulations.
A novel approach in constructing deviations of the Kerr spacetime whereas
the symmetries can be preserved is presented. The method was applied
trivially in all known classical black-hole spacetimes tested, while
provides the possibility of testing and inventing deformations of Kerr in
a quick and innovative way. The methodology is based on earlier work by
This page contains a preliminary list of landmark papers suggested by group members to be discussed in Journal Club sessions. Papers are organized by chronological order.

C. Herdeiro was one of the guests of Jornal 2, of RTP2, on October 6th, to talk about the Physics Nobel prize 2020. See the interview here (from 19:52 onwards).
The Scientific background document on the 2020 Nobel Physics Prize mentions the paper by C. Herdeiro and José S. Lemos (from IST Lisbon) on the genesis of the name "black hole" available in the arXiv (in English) and originally pubished in "Gazeta de Física" (in Portuguese).
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
