Meeting with a scientist

Talking about the Universe, black holes and what a scientist does was the challenge for the "Meeting with a Scientist" event, with Gr@v's C. Herdeiro, organized by Fábrica, the outreach centre in Aveiro (Centro Ciência Viva). The audience (fourth graders) really proved the famed curiosity of the young ones.

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.

Event type

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.
