I will discuss new degrees of freedom of gravity as motivated by string theory. Although they are expected to be generically quantum mechanical, classes of such states are coherent enough to admit classical descriptions in Einstein gravity. I will explain how to describe them as novel ultra-compact geometries without horizon or singularity.
Cosmological tests on non-metricity based theories of gravity

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
C. Herdeiro gave an invited colloquium at the Institutt for teoretisk astrofysikk of the University of Oslo Norway on September 1st 2023.
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.
