Welcome to Gr@v

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.

Gr@v paper in Physical Review X

papers

An article on the parameter inference from gravitational wave signals using a novel methodology based on the Newman-Penrose scalar was published this month (December 2023) in Physical Review X. The article is co-authored by Gr@v members C. Herdeiro and E. Radu. PRX has similar quality standards as Physical Review Letters but for longer papers. It has an impact factor of 12.5 (2022).
