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.

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.

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.

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.

Nico Sanchis-Gual and Rodrigo Vicente, both based at IST-Lisbon, visited this week. Rodrigo delivered a seminar on "Moving black holes: Energy extraction, absorption cross section, and the ring of fire".

Group members Sonia Anton and Carlos Herdeiro, as well as Tiago Campante from IA and U. Porto, participated in the outreach activity "Café de Ciência", at Fábrica, Centro de Ciência Viva de Aveiro, as part of the conference cycle "À descoberta do Universo" promoted by Tiago Campante.
