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
Speaker
Marco de Cesare (University of the Basque Country, Spain)
Event date
Venue
online (only)
Event type
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.
Nico farewell lunch
Nico Sanchis-Gual is moving back to Valencia (his alma mater) and we celebrated Nico's friendship and collaboration with the group with a farewell lunch. See you soon Nico!
Introduction to RNS: building a Neutron Star model

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.
