Composite Higgs Models are still viable extensions of the Standard Model. I will first review the basic idea of this class of models.
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).
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].
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.
During the week of 13-17 November 2023 we had the pleasure to host Rodrigo Vicente from IFAE, U. Barcelona and Roman Pasechnik from the U. Lund to tell us about their latest research. Of course, discussions are better over a nice lunch!
Recent horizon-scale images of Messier 87* and Sagittarius A* have been used to demonstrate that their spacetimes are well-described by the Ke
