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.
A call for a 2-year post-doctoral research fellowship in Strong Gravity, within the research grant Gravitational waves, black holes, and fundamental physics, 2022.04560.PTDC, is now open until 11 October 2023. To apply, please see the Euraxess announcement here.

Gravitational-wave observations of extreme mass ratio inspirals (EMRIs) hold incredible potential to probe gravity, astrophysical and exotic environments. One of the main effects of astrophysical environments — in particular active galactic nuclei — is the torque exerted by their gaseous disk, which forces EMRIs to “migrate” (mostly) inward like planets.
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.
Ultralight dark matter is an exciting alternative to the standard cold dark matter paradigm, reproducing its large scale predictions, while solving most of its potential tension with small scale observations (like the "cusp-core" and "missing satellites" problems).
