Signatures of domain wall networks: from gravitational waves to primordial black holes

The Domain Wall (DW) problem is the fact that DW networks that result from the spontaneous breaking of discrete symmetries tend to dominate the universe's energy budget.
However, if the symmetry is not exact the network annihilates and the problem turns into a virtue, as the network tends to be an abundant component before its collapse, and is thus easier to probe.
Confinement of exotic energy

Venue
On-site: Sala Sousa Pinto
Event type
By solving the Einstein's field equations, we derive several
configurations of compact objects with a nucleus of exotic energy in a
static and spherically symmetric spacetime. In this talk I describe the
derivation and several properties of the configurations, including the
fact that in some of these objects can be reached a compacity as close to

XVI Black Holes Workshop in Porto
15 years after the first edition of the Black Holes Workshop that took place at the Faculty of Sciences of Porto University, the XVI Black Holes Workshop returned to Porto, this time in the Faculty of Engineering. The next edition will take place at the University of Aveiro on 19-20 December 2024.
Gr@v paper in Physical Review X
An article on the parameter inference from gravitational wave signals using a novel methodology based on the Newman-Penrose scalar was published this month (December 2023) in Physical Review X. The article is co-authored by Gr@v members C. Herdeiro and E. Radu. PRX has similar quality standards as Physical Review Letters but for longer papers. It has an impact factor of 12.5 (2022).
