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 December 2020 issue of the Aveiro University magazine "Linhas UA" includes a feature article covering work at Gr@v and the mysteries of black holes. Check this issue here.
Can a black hole be different from the Kerr paradigm depending on its spin? In paper to publishd in Physical Review Letters, Gr@v members C. Herdeiro and E. Radu, in collaboration with H. Silva and N. Yunes (U. Illinois at Urbana-Champaigne, US) and T. Sotirou (U. Nottingham, UK), show that the phenomenon of spontaneous scalarisation can lead to non-Kerr black holes, only if they spin fast enough.
Citation metrics are widely used and misused. A publicly available database of over 100,000 top-scientists, science-wide, (recently updated) provides standardized information on citations. Two Gr@v researchers, C. Herdeiro and E. Radu, are ranked amongst these top-scientists. The 2020 data can be fetched here and the 2019 paper can be found here.
João Oliveira successfully defended his Ph.D. thesis on Friday 20th November 2020. The committee, presided by Prof. A. Botelho and composed by Profs. D. Astefanesi, M. Zilhão, M. Piedade Ramos, E. Radu and C. Herdeiro (advisor) unanimously approved the thesis entitled "Aspects of Einstein-Maxwell-scalar models: Solitons, Duality and Scalarisation". Congratulations João!
The 2020 FCT call for Scientific Research & Technological Development projects had 5847 applications, of which 3317 were considered eligible and 312 recommended for funding. In the Physical Sciences panel there were 139 applications; Gr@v's project, led by C.Herdeiro, a synergy between the different expertise of the group (strong gravity, astrophysics and high energy physics) was ranked first.
Pedro Cunha was one of the 7 selected researchers for a junior grant, nationwide, within 76 applicants in the Physical Sciences panel, in the third individual call for scientific employment stimulus, promoted by FCT. Pedro (re)joined our group as a post-doc in October 2020, after being a post-doctoral researcher at the Max Planck institute for gravitational physics in Golm, Germany. Congratulations Pedro!
Nicolas Sanchis-Gual, the only member of the LIGO-Virgo-Kagra collaboration working in Portugal, officially joined Gr@v and our research unit CIDMA. After his Ph.D. from the University of Valencia, Nico worked as a postdoctoral researcher at CENTRA-IST. He is an expert on Numerical Relativity and Gravitational Waves from dynamical binaries. Welcome Nico!
