Cosmology News & Events
ICGC 24 and ICRAC 24
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.
From Hubble to Bubble - gravitational waves from phase transitions after inflation
Speaker
Andreas Mantziris (University of Porto)
Event date
Venue
Hybrid: Sala Sousa Pinto and Zoom
Event type
The prospect of a stochastic gravitational wave (GW) background from the primordial universe offers a promising new window for cosmology and fundamental physics.
Black Hole Superradiance video
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!
Signatures of domain wall networks: from gravitational waves to primordial black holes
Speaker
Ricardo Ferreira (University of Coimbra)
Event date
Venue
Hybrid: Sala Sousa Pinto and Zoom
Event type
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.
Phenomenology of Composite Higgs Models with a fermionic UV completion
Speaker
Werner Porod (Würzburg University)
Event date
Venue
On-site: Room 11.2.21
Event type
Composite Higgs Models are still viable extensions of the Standard Model. I will first review the basic idea of this class of models.
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.
Research grant in strong gravity for M.Sc. holders
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.
The non-spherical ground state of Proca stars
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].
Iranian Conference on High Energy Physics
The Iranian Conference on High Energy Physics took place from 20-22 November 2023 (online). C. Herdeiro was one of the Plenary Speakers. See the programme here.
