The COST Advanced School on the "Physics of Dark Matter and Hidden Sectors" will take place in Lund, Sweeden, from October 18-21st 2021. Gr@v members C. Herdeiro, A. Morais and F. Freitas are amongst the invited lecturers.
Testing the Black-Hole Area Law with GW150914
Maximiliano Isi, Will M. Farr, Matthew Giesler, Mark A. Scheel, and Saul A. Teukolsky
Phys. Rev. Lett. 127, 011103
The Gr@v paper "Kerr black holes with scalar hair" reached the landmark of 500 citations in the INSPIRE database.
The Spanish-Portuguese Relativity Meeting 2021 took place online from 13-16 September 2021, organized by our group. With over 200 registered participants and 95 talks (invited, contributed and one public lecture), the meeting exhibited the interdisciplinarity of this thriving field. Talk slides can be found in the program webpage. We hope to have a face to face EREP 2022!
E. Barausse (SISSA, Italy) and C. Herdeiro (Gr@v) are the guest editors for a Classical and Quantum Gravity Focus issue on the Impact of EHT Observations for General Relativity. For more information see the focus issue webpage.
Lorenzo Annulli (Ph.D. IST-Lisbon, 2021) and Etevaldo Costa Filho (M.Sc. U. São Paulo, 2020), joined our group as a new post-doctoral researcher and Ph.D. student, respectively, from the fall 2021. Welcome!
The XIV Black Holes Workshop will be held at the University of Aveiro, on 20-21 December 2021. Registration was open on September 1st 2021. See the webpage for more information.
Full Name: Etevaldo dos Santos Costa Filho
C. Herdeiro was one of the invited lecturers of the 10th school on astrophysics and gravitation, held from 2-7 September at IST-Lisbon, delivering a course on "Theoretical and Observational Cosmology".
According to the Penrose's cosmic censorship conjecture, curvature singularities in General Relativity are always hidden by an horizon. This implies that the charge-to-mass ratio of a spherically symmetric charged black hole in Einstein-Maxwell theory cannot be larger than one.
