Evolving black hole with scalar field accretion

I will present recent results on evolving black holes in general relativity. Approximate analytical solutions are obtained by expanding the Einstein field equations close to the trapping horizon for a dynamical spherically symmetric black hole in the presence of a minimally coupled self-interacting scalar field.

Gravitational waves detected from the GW170817 neutron star merger event and complementary information from its electromagnetic counterpart were pivotal in confirming the broad picture describing the possible outcomes of a binary neutron star (BNS) merger. In order to study this challenging event through numerical relativity, it is needed to start from an initial configuration.

Miguel Zilhão joins Gr@v

Miguel Zilhão joins Gr@v from January 1st 2022 under a two-years research position. Miguel is an expert on strong gravity, in particular in numerical relativity, a technique he has applied in multiple contexts, ranging from astrophysics to AdS/CFT. He was a former Ph.D. student in Porto University and Gr@v (graduated in 2012) and since then has been a researcher at Rochester Institute of Technology (USA), University of Barcelona (Spain) and IST-Lisbon.
