The XIV School of the Division of Gravitation and Mathematical Physics of the Mexican Physics Society and the VIIIth Scalar field dark matter workshop took place from 25-29 Sep 2023 and 29-30 Sep 2023 in Cancun, Mexico. Gr@v members C. Herdeiro and H. Olivares, as well as former member J. C. Degollado were amongst the invited speaks, and A. Morais presented also a communication.

Primordial black holes (PBHs) might form in the early universe and could comprise a significant fraction of the dark matter. If they are generated due to enhanced scalar perturbations at small scales, their formation is inevitably accompanied by the emission of gravitational waves (GWs) that could be seen by current and future GW experiments.
The "New horizons for Psi school and workshop" will take place at IST Lisbon, 1-5 July 2024, with the participation of Gr@v members as speakers.
C. Herdeiro gave an invited colloquium at the Institutt for teoretisk astrofysikk of the University of Oslo Norway on September 1st 2023.
The paper "Two spinning black holes balanced by their synchronised scalar hair", describing the first construction of two asymptotically flat, neutral, spinning black holes in equilibrium, regular on and outside their event horizon, supported by their "hair", was published in Physical Review Letters and highlighted as Editors' Suggestion.
