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.
Yasha Shnir (from Dubna, Russia) and Massimo Vaglio (from Rome, Italy) visited our group in June-July 2021 within the COST action GWVerse, to strengthen the collaboration with different group members, on several aspects of strong gravity. Thank you for your visit!
Gr@v Ph.D. student Jorge Delgado got a best pitch award for his pitch (short talk) in the UA Research Summit 2021, in the session for students of the MAP-Fis Ph.D. programme. Congratulations Jorge!
A call for a 2 years postdoctoral grant in Strong Gravity, within the research grant “Testing the Kerr hypothesis with gravitational waves and lensing", PTDC / FIS-AST / 3041/2020, is open from 1 to 20 August 2021. See attached document for details (in Portuguese) or the Euraxess announcement (in Portuguese and English) here.
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.
