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.
Group members J. Delgado, A. Pombo, N. Sanchis-Gual (invited talk in parallel session), N. Santos presented oral communications in the 16th Marcel Grossmann Meeting (MG16). C. Herdeiro co-chaired the parallel session BS1.
Bosonic stars are multipurpose gravitational solitions and dark matter contenders. Yet, as shown in a paper co-authored by Gr@v members. N. Sanchis-Gual, C. Herdeiro and E. Radu published in Physical Review Letters, the known solutions are just the just the tip of the iceberg... and the new configurations unveil a mechanism that provides dynamical stability.
A call for a 1 year grant for a M.Sc.holder, within the research grant “Testing the Kerr hypothesis with gravitational waves and lensing", PTDC/FIS-AST/3041/2020, is open. The call closes on June 30th 2021.

In a paper published in Phys. Rev. Lett, Gr@v member Nico Sanchis-Gual and co-authors reports a degeneracy between the gravitational-wave signals emitted in quasi-circular precessing black-hole mergers and those from extremely eccentric mergers, namely head-on collisions.
C. Herdeiro was the invited speaker of the Tübingen Einstein seminar on April 16 2021.
A call for a 1 year postdoctoral grant in High Energy Physics, within the research grant “From Higgs phenomenology to the unification of fundamental interactions", PTDC / FIS-PAR / 31000/2017, is open from the 19th of April to the 14th of May 2021. See the eracareers announcement (in Portuguese and English) here.
Celebrating the 2020 Physics Nobel Prize for Black Holes, here is an outreach article published in Gazeta de Física (published by the Portuguese Physics Society) by C. Herdeiro. The article pdf can be found in attachment.
