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!
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.
Composite Higgs Models are still viable extensions of the Standard Model. I will first review the basic idea of this class of models.
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.
A call for a 7-month research grant in Strong Gravity for M.Sc. holders, within the research grant Gravitational waves and black holes as ultralight dark matter particle detectors, CERN/FIS-PAR/0024/2021, is open from December 7th to 21st, 2023. See attached document for details or the Euraxess announcement here.
Proca stars, first discovered in this paper, are a vector cousin of the well known model of scalar boson stars - see these papers for reviews [1], [2] and comparisons between the two models [3], [4].
