Gr@v is a team of researchers, based at the Mathematics and Physics Department of Aveiro University, Portugal, working on strong gravity, astrophysics 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.
Gr@v members C. Herdeiro and E. Radu, were two of the speakers of the Mini-workshop on "Black holes and symmetries" at the Instituto de Física, Pontifica Universidad Católica Valparaíso, Chile. The workshop was organised by Olivera Moskovic and Dumitru Astefanesei. The other speaker was Marc Henneaux from the Université Libre de Bruxelles, Belgium.
Nelson Eiró visited Gr@v just before successfully defending his M.Sc. thesis on "Strong lensing of light and shadow of a Black Hole surrounded by a heavy accretion disk", at IST-Lisbon, supervised by C. Herdeiro and P. Cunha. This visit coincided with the beginning of a long term visit by Aichen and Ruyong Li, both graduates from Beijing University of Technology.
Nico Sanchis-Gual and Nuno Santos visited Gr@v. Nico gave a seminar on "Non-linear dynamics of spinning bosonic stars: formation and stability". Nuno, an IST graduate, will join Gr@v as a PhD student in 2020, having been the top ranked candidate in the 2019 Individual FCT grant call in the Physics panel.
In the framework of the COST action MW-Gaia, related with the Gaia (ESA) mission, for which Gr@v member Sonia Anton serves as MC member, a 3-days workshop on "Astrometry and gravitation - A dynamical view of the sky" is being organised on 4-6 December 2019, at the Observatoire de la Côte d’Azur, Mont Gros site, Nice, France.

Professor Marcus Werner from Kyoto University visited Gr@v and presented a seminar on Optical Geometry and Constructive Gravity, on September 30th 2019.
The XII Black Holes Workshop, an annual series of meetings organised by the Portuguese strong gravity community since 2008, will take place in Guimarães, on December 19-20, 2019. More information here.
A long standing problem in General Relativity has been the dynamical properties of spinning bosonic stars. In the paper "Non-linear dynamics of spinning bosonic stars: formation and stability", to appear in Physical Review Letters, the dynamical behaviour of these objects has been unveiled.
