In this talk, we consider a scenario in which an extended reheating scenario can be described analogously to the so-called scalar field dark matter model.
The 3rd Workshop on Compact Objects, Gravitational Waves and Deep Learning will take place on 23 Sep 2022 at the University of Minho, after the first and second workshops of this series in Aveiro and Valencia, repectively.
Gr@v member C. Herdeiro was one of the invited speakers of "Física 2022" the 23rd national conference of the Portuguese Physics Society, delivering the talk "Buracos Negros: de uma equação ao Nobel" (photo courtesy of A. Folhas).
We bid farewell (with a Peruvian flavour) to Alexandre Pombo, that will join Charles University in Prague for his next post-doctoral position. See you soon Alexandre!
A group of Gr@v members, including J. Delgado, A. Pombo, J. Novo, N. Santos and I. Sengo, represented the group at the 2022 Spanish-Portuguese relativity meeting, in Salamanca, delivering talks on their latest work. Former member J. Oliveira, also joined them for the group photo!
The XV Black Holes Workshop will take place at ISCTE, University Institute of Lisbon, on 19-20 December 2022. Registration opens on September 19th.
A new staff exchange network - NewFunFiCO - was chosen for funding within the Horizon-MSCA-2021-SE-01 call. The network has nodes at Aveiro University (Portugal, coordinator), University of Valencia (Spain), Johann Wolfgang Goethe-Universitaet Frankfurt Am Main (Germany), Universidad Nacional Autonoma de Mexico (Mexico), Universidade Federal do Pará (Brazil) and the Chinese University of Hong Kong (China). The network will start on January 1st 2023 and have a lifetime of 4 years.
Our group is co-organizing the VIII Amazonian Workshop on Gravity and Analogue Models, to be held in Belém, Brazil, from 21-25 November 2022. This meeting is also promoted by the FunFiCO network, for which U. Federal do Pará, in Belém, is one of the nodes, coordinated by Prof. Luis Carlos Crispino.
Gravitational wave detections, images of black hole shadows, and other impressive developments in observational astronomy allow us to study strong gravity systems in a completely new way. Being immersed in the universe, these systems are surrounded by plasma, which can be described by the equations of magnetohydrodynamics (MHD).
I will sketch motivations, ambitions and challenges of quantum gravity, how we have got to where we are, and discuss promising current and future direction, focusing on nonperturbative quantum field-theoretic approaches. No expert knowledge on quantum gravity will be required.
