Discussion on the paper "Gravitational footprints of massive neutrinos and lepton number breaking"
CIDMA, the research unit Gr@v integrates, has annouced two one year postdoctoral positions starting in September 2020. Candidates should hold a Ph.D. in Mathematics or related areas (the scientific areas of Gr@v are elegible). The application period is May 14th-31st. More details can be found here and here.
Discussion on the paper "Stationary black holes and light rings", ArXiv:2003.06445 to appear in Physical Review Letters, as an Editor's Suggestion.
Here, the numerical data described in the paper "Black holes with synchronised Proca hair: linear clouds and fundamental non-linear solutions", arXiv:2004.09536 [gr-qc] [1], is made available for public use.
This data pertains the fundamental states (n=0) of these hairy black holes and spinning Proca stars. Some data for the excited states (n=1) was previously made available here.
Discussion on the paper "Counterterm method and thermodynamics of Hairy Black Holes in a Vector-Tensor theory with Abelian gauge symmetry breaking ", ArXiv:2004.08329
In the article "Stationary black holes and light rings" by P. Cunha and C. Herdeiro, published in Physical Review Letters, as Editor's Suggestion, a theorem is proven establishing that, under very generic conditions, any black hole must have a light ring.
Research cannot stop, even in this exceptional time! Gr@v member keep meeting virtually to push the group activities.
Recently, a novel modified theory of gravity that claims to bypass Lovelock's theorem whilst preserving the number of gravitational degrees of freedom has attracted a great deal of attention.

A recent breakthrough in the separability of the Proca equation in Kerr spacetime opened up new opportunities for a thorough study of fast-growi
