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.
The detection of gravitational waves has been one of the most exciting scientific developments of the XXIst century. These detections are theory-driven, they rely on the existence of waveform libraries, which have been constructed for binary black holes and neutron stars. Gr@v members have collaborated on the construction of the first waveform catalogue for exotic compact objects, an effort led by former Gr@v member Nicolas Sanchis Gual (now at the U. Valencia).
The black hole merger in scalar-Gauss-Bonnet gravity can lead to dynamical descalarization this is a spontaneous release of the scalar
hair of the newly formed black hole. Depending on the exact form of the Gauss-Bonnet coupling function, the stable scalarized solutions
Non-linear extensions of Proca theory are pathological at large field amplitudes. I will explain why. I will also discuss a separate criterion for breakdown proposed in the literature, and why it does not correspond to a real physical problem
The theory of General Relativity has successfully passed a large number of observational tests. The theory has been extensively tested in the weak-field regime with experiments in the Solar System and observations of binary pulsars.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
