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.
The machine learning work by Gr@v member Felipe Freitas for detecting gravitational waves was awarded a prize of US $4000 in QHack 2021, being ranked in the top 20 amongst over 300 submitted projects.
A list of the impact of scientists' careers was revealed in late 2020 in a study coordinated by John Ioannidis, from Stanford University (USA). It includes 34 scientists from the University of Aveiro (UA), including 2 from Gr@v. Read the UA coverage here.
Gr@v members co-author a paper in Physical Review Letters suggesting GW190521 may be a hint of a new dark matter particle.
Traversable wormholes are intriguing geometries in General Relativity, which have leaked into science fiction becoming known to the general public. Yet, they typically require exotic matter. In a paper to appear in Phys. Rev. Lett., as Editor's suggestion, Gr@v member E. Radu, together with J. Blázquez-Salcedo (Complutense U.) and C. Knoll (U. Oldenburg), have shown how to construct wormholes in General Relativity without the use of exotic matter (or modified gravity).
The paper "Stationary black holes and light rings", by P. Cunha and C. Herdeiro, published in 2020 in Physical Review Letters as Editor's Suggestion, has been placed in the top 5% of all research outputs scored by Altmetric.
C. Herdeiro was one of the invited speakers of the 740ths WEH Seminar "Experimental Tests and Signatures of Modified and Quantum Gravity", held from 1-5 Feb 2021. The talks of the meeting were recorded and are available here. The page is password protected.
FCT announced a call for research contracts for Ph.D. holders, from 29 January to 26 February 2021. If you are looking for a post-doctoral opportunity please contact the group coordinator to discuss a possible application.
