C. Herdeiro was one of the plenary invited speakers of the International Conference on Gravitation and Cosmology (ICGC 24) and the International Conference on Relativistic Astrophysics and Cosmology (ICRAC 24) that took place in Lahore, Pakistan on 29-31 Jan and 1-2 Feb 2024. Wonderful hospitality and great interactions. Science brings people together.
The prospect of a stochastic gravitational wave (GW) background from the primordial universe offers a promising new window for cosmology and fundamental physics.
Visakan Balakumar, Marie Curie seconded fellow within the RISE FunFiCO project, coordinated by Gr@v, authored a YouTube outreach video on superradiance. Check it out here!
Read here the phys.org coverage of two papers published in Phys. Rev. X and Phys. Rev. D in December 2023, involving members of Gr@v.
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.
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
Composite Higgs Models are still viable extensions of the Standard Model. I will first review the basic idea of this class of models.
