CIDMA has an open call for two junior researchers for the period 2020-2023. Candidates should hold a Ph.D. in Mathematics or related areas (the scientific areas of Gr@v are elegible). The application period closes on Aug 5 2020.
The paper "EHT Constraint on the Ultralight Scalar Hair of the M87 Supermassive Black Hole" by P. Cunha, C. Herdeiro and E. Radu, was selected as one of the 2019 Editor's Choice of the journal Universe.
The U. Aveiro Research Summit took place on 24-26 June 2020. Our group contribute with four student pitches (by A. Pombo, J. Delgado, L. Ventura and J. Oliveira). This year's edition of the Reseach@UA magazine included one Gr@v article as a 2019 reseach highlight and two Gr@v papers in the top 10 cited papers (2014-2019).
The propagation of electromagnetic waves in vacuum is often described within the geometrical optics approximation, which predicts that wave rays follow null geodesics. However, this model is valid only in the limit of infinitely high frequencies.
Pandemia doesn't stop us! Gr@v webinars are the group's virtual meeting place, taking place every week. Interested collegues that wish to join may do so by contacting the group's scientific coordinator.
In this talk, I will briefly introduce our recent work of Dirac quasinormal modes (QNMs) on asymptotically anti-de Sitter (AdS) spacetimes by imposing Robin type vanishing energy flux boundary conditions (BCs). We first study neutral Dirac fields propagating on a Schwarzschild-AdS spacetimes.
The paper "Stationary black holes and light rings" recently published in PRL as editor's suggestion was covered by Phys.Org. Read here the story.
Because of the universality of gravitational interactions, it is generally expected that a stochastic gravitational wave (GW) ba
