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.
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.
Oleg Tsupko, an expert in several strong gravity topics including lensing and black hole shadows, joins Gr@v as a CEEC researcher from April 2026. Welcome Oleg!
I will discuss the first 3D-general relativistic magnetohydrodynamic (GRMHD) simulation of sustained accretion onto a horizonless singularity in which matter falls onto the central object rather than being accumulated outside of it or expelled in outflows.
