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.
The "New horizons for Psi school and workshop" will take place at IST Lisbon, 1-5 July 2024, with the participation of Gr@v members as speakers.
The paper "Two spinning black holes balanced by their synchronised scalar hair", describing the first construction of two asymptotically flat, neutral, spinning black holes in equilibrium, regular on and outside their event horizon, supported by their "hair", was published in Physical Review Letters and highlighted as Editors' Suggestion.
A call for a 2-year post-doctoral grant in Strong Gravity, within the research grant Gravitational waves, black holes, and fundamental physics, 2022.04560.PTDC, is open from 1 to 20 August 2023. See attached document for details or the Euraxess announcement here.
The VIII International Meeting of "Casa das Ciências" took place at the University of Aveiro from 17-19 July 2023, with the participation of hundreds of teachers. C. Herdeiro was one of the invited speakers talking about black holes and gravitational waves, with the moderation of M. Zilhão.
The VIII scalar field dark matter workshop will take place in Playa del Carmen, Mexico, on 29-30 September 2023. C. Herdeiro is one of the invited speakers.
Boson stars are a remarkable type of self-gravitating soliton, which admits multipolar configurations. The simplest non-spherical stars, but still static, are the dipoles, but are they dynamically stable? In the paper "Self-interacting dipolar boson stars and their dynamics", it is shown self-interactions help make these dipoles dynamically robust.
