On March 1, Gr@v member Nuno M. Santos gave an invited seminar at the Central European Institute for Cosmology and Fundamental Physics (CEICO), in Prague. The seminar, entitled "Synchronized bosonic hair: equilibrium solutions", focused on the physics of black holes with synchronized hair.
He was hosted by Alexandre Pombo, a former Gr@v member, and Ippocratis Saltas.

The last four sessions of the Gr@v group seminars are now on YouTube in our dedicated channel https://www.youtube.com/@Gravchannel. These include the talks from Raimon Luna (University of Valencia), Stephen Green (Univeristy of Nottingham), Beatrice Bonga (Radboud University) and Visakan Balakumar (Sheffield University).
On February 23, Gr@v member Lorenzo Annulli gave an invited seminar at the University of Cagliari and INFN - Cagliari Unit, in the beautiful seaside city of Cagliari, Sardinia. The seminar, entitled "The close limit approximation of compact objects: black holes, horizonless bodies and future applications" , focused on black holes, gravitational waves and their physics.
Lorenzo has been hosted by Prof. Mariano Cadoni, Andrea Sanna, Mauro Oi and the HEP Colloquia Organizing Committee; many thanks to all of them!
The gravity group in Aveiro is organizing a retreat-type group meeting, with a few guests, designed for a period of concentrated discussion and strategic thinking. The meeting, called "State of the art techniques in Strong gravity", is scheduled for 26-28 April 2023, in Hotel Vouga, São Pedro do Sul, Portugal.
This meeting will be held fully on-site, with no online component.
Gr@v member C. Herdeiro inaugurated the ARCO Distinguish Guest Lecture series at the Open University, Israel, on Feb 6th 2023, with a seminar on the "Fate of the Light Ring instability".
The European Einstein Toolkit Meeting 2023 will be held at the University of Aveiro, hosted by our group, from 19–23 June 2023. More info on the event website.
The paper "Exotic compact objects and the fate of the light ring instability" has been selected as Editor's suggestion in Physical Review Letters (published February 7th 2023) and was also featured in Physics Magazine, an online publication from the American Physical Society (APS) that reports on papers in the Physical Review Journals.
