In the context of a special class of tensor-multi-scalar theories of gravity for which the target-space metric admits an isometr
Group members Sonia Anton and Carlos Herdeiro, as well as Tiago Campante from IA and U. Porto, participated in the outreach activity "Café de Ciência", at Fábrica, Centro de Ciência Viva de Aveiro, as part of the conference cycle "À descoberta do Universo" promoted by Tiago Campante.
Jose Blázquez-Salcedo is visiting the group within a (one month) short term scientific mission of the COST action GWverse. He presented a seminar on "Quasi-normal modes of neutron stars in R^2 gravity".
This is the fourth of a mini-course (four lectures) on black hole thermodynamics. The lectures will be on January 16, 24, 31 and February 6.
In this talk I will firstly give a brief introduction on what bosonic stars are and why should we be interested in studying them. Then, I will present a study of the non-linear dynamics of both boson(scalar) and Proca(vector) stars, through numerical relativity techniques. I will depict three different physical scenarios.
This is the third of a mini-course (four lectures) on black hole thermodynamics. The lectures will be on January 16, 24, 31 and February 6.
The CIDMA research unit meeting 2020 took place on the 22-23 January at the Mathematics Department of Aveiro University. João Oliveira and Sonia Anton were the two Gr@v representatives in the scientific programme.
The Spanish-Portuguese Relativity Meeting (EREP2020) will take place at the University of Aveiro, from 14-17 September 2020. Registration will open on February 1st.
Penrose process remains a textbook example of a mechanism for energy extraction from black holes, yet there are many impediments to its practical viability. The longest known problem is that it requires a particle to split into two fragments with very high relative velocity.
This is the second of a mini-course (four lectures) on black hole thermodynamics. The lectures will be on January 16, 24, 31 and February 7.
