Gr@v is a team of researchers, based at the Mathematics and Physics Department of Aveiro University, Portugal, working on strong gravity and high energy physics. The group was established in 2010. In January 2015 Gr@v integrated the FCT funded CIDMA research unit (UIDB/04106/2020 and UIDP/04106/2020), as the Gravitational Geometry and Dynamics research group. The group scientific coordinator is C. Herdeiro.
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.
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).
In the 5th FCT individual contest for stimulous of research, Miguel Zilhão, Guilherme Raposo and Hector Olivares obtained 6 years research positions to join Gr@v.
In the paper "The fate of the light-ring instability" Gr@v members P. Cunha, C. Herdeiro and E. Radu, together with former member, currently at the U. Valencia, N. Sanchis-Gual, have unveiled the mystery of the fate of a large class of horizonless ultracompact objects, that could be potential black hole foils.
A long standing intriguing possibility is if the astrophysical black hole candidates could be some other kind of mysterious objects but without event horizons, the defining property of black holes.
