[email protected] is a team of researchers, based at the University of Aveiro, Portugal, working on gravitational physics in the context of astrophysics, cosmology and high energy physics. The group was established in 2010. In January 2015 [email protected] integrated the FCT funded CIDMA research unit (project UID/MAT/04106/2013), as the Gravitational Geometry and Dynamics research group.
[email protected] Ph.D. students Alexandre Pombo, João Oliveira and Jorge Delgado visited Belém, Brazil as members of the FunFiCO Marie Curie RISE project. Their visit coincided with the VII Amazonian Workshop on Gravity and analogue models, where they presented their work, and the Amazonian High Studies School in Theoretical Physics where they attended courses on Numerical Relativity and Gravitational Lensing.
A long standing problem in General Relativity has been the dynamical properties of spinning bosonic stars. In the paper "Non-linear dynamics of spinning bosonic stars: formation and stability", a collaboration between Aveiro U., IST-Lisbon and Valencia U. (Spain), including N. Sanchis-Gual, F. Di Giovanni, M. Zilhão, C. Herdeiro, P. Cerda-Duran, J. A. Font and E. Radu, fully non-linear evolutions of the formation and evolution of both scalar and vector spinning bosonic stars have been performed.
Current and former [email protected] members met at the 22nd International Conference on General Relativity and Gravitation (GR22) in Valencia, Spain. Great talks and great discussions!
The paper "Spontaneously Scalarized Kerr Black Holes in Extended Scalar-Tensor–Gauss-Bonnet Gravity" published in Physical Review Letters (PRL), authored by [email protected] members Pedro Cunha and Eugen Radu (co-authored by Carlos Herdeiro from IST-Lisbon), was selected to feature on the cover of the 3rd July 2019 issue of PRL.
On May 29th 1919 Eddington and Cottingham measured the position of stars near the sun during a total eclipse observed at the island of Príncipe, off the west African coast. Their results, together with the ones of another expedition undertaken by Crommelin and Davidson to Sobral (Brazil), were announced on November 6th 1919 and confirmed the General Theory of Relativity. This openned a new era in our understanding of gravity, space, time and matter... and made Einstein world famous.
In a recent paper "Spontaneous scalarisation of charged black holes: coupling dependence and dynamical features", [arXiv:1902.05079], by [email protected] members A. Pombo and E. Radu, in collaboration with a group at IST-Lisbon (P. Fernandes, C. Herdeiro and N. Sanchis-Gual), fully non-linear evolutions of the process of spontaneous scalarisation of charged black holes.
