Black hole spectroscopy is a powerful tool to probe the Kerr nature of astrophysical compact objects and their environment.
On March 1, Gr@v member Miguel Zilhão gave an invited seminar at the Albert Einstein Institute in Potsdam, at the Astrophysical and Cosmological Relativity group. The seminar was entitled "The piercing of a boson star by a black hole", and focused on the dynamics of scalar fields and boson stars in the presence of black holes.
Celebrating the recent "UA Investigador" prize and the group's many (great) guests on Mar 7th 2023. Thank you to Prof. Carolina Benone (U. F. do Pará, Brazil) for the visit and welcome to Prof. Maurício Richartz (U. F. ABC, Brazil), who is joining us for a month. And we also got the short visit of Francisco Duque, from IST-Lisbon, who presented the group seminar on Mar 8th.

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.
