Primordial Black Holes from Inflation: recent challenges and opportunities in the GW era

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.
Cosmological tests on non-metricity based theories of gravity

Hybrid: Room 11.2.21 and Zoom
Event type
In this seminar, we study and present constraints for two cosmological models based on non-metric theories of gravity, referred to as f(Q) gravity, using both current datasets and forecast Standard Siren events.
The first model is the most general f(Q) model that replicates a ΛCDM background, with deviatio
New horizons for Psi
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.
Colloquium in Oslo

Two spinning black holes in equilibrium in PRL as Editors' Suggestion
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.
