Event type
We study traversable wormhole
solutions in pure gauged $N\!=\!2$ supergravity with and without
electromagnetic fields, which are locally isometric under
$\mathrm{SO}(2,1)\!\times\!\mathrm{SO}(1,1)$.
Two junior researcher positions at CIDMA
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.
Editor's choice in "Universe"
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.
UA Research Summit
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 gravitational spin Hall effect of light

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.
Gr@v webinars
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.
Dirac QNMs on asymptotically anti-de Sitter spacetimes with Robin boundary conditions
Speaker

Event date
Venue
online
Event type
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.
Light ring theorem covered by Phys.Org
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.
