Strong Gravity News & Events

A four months grant for a student enrolled in a doctorate programme is open, to start on June 1st 2026. More informations here. 

Neutron stars offer unique natural laboratories for probing the interaction between dark matter and baryonic matter — a central open question in modern astrophysics and high-energy physics. In this talk, I will present our recent work modeling dark matter as an ultralight bosonic field that accretes onto neutron stars, forming composite objects — fermion-boson stars — bound through gravity.

In April 2026 we received the visits of Maryem Jemri (Rabat) and Justin Feng (Prague). Thank you for your seminars and the great scientific interactions!

Inspired by noncommutative geometry in string theory, we introduce extended derivatives in black hole physics by incorporating a real antisymmetric rank-2 tensor, exhibiting similarities with certain string-theoretic fields.

Gr@v is hosting the visits of Yasha Shnir, long time group collaborator, under an FCT mobility grant, and Mario Luciano Navarro, Ph.D. student from Valencia in the spring 2026. In the photo Yasha and Mario enjoy a bit of sunshine after the weekly group lunch. 

This talk presents two distinct problems in gravitational physics that are connected through the use of solution-generating techniques within Einstein–Maxwell–scalar theory. First, we construct new vacuum solutions of Einstein’s equations starting from electrovacuum configurations embedded in external electromagnetic backgrounds.

Our group is co-organizing the X Amazonian Workshop on Gravity and Analogue Models from 29 June to 3 July in Belém, Brazil. More info here.

The NewFunFiCO network is organizing a workshop in Frankfurt from 15-17 June 2026. More info here.
