Photon rings and shadows of Kerr black holes immersed in a swirling universe
We discuss the existence and locations of light rings in the spacetime of a Kerr black hole immersed in a swirling universe– in other words, the immersion of a rotating black hole into a rotating background. As the spin-spin interaction between the black hole and the background breaks the upper-lower hemisphere symmetry, it allows for interesting new features.
Outreach talk by Manuel Mariano
During a secondment to Belém, within the NewFunFiCO project, Gr@v Ph.D. student Manuel Mariano gave a public talk
Quasi-integrability in classical field theories
We present a general inverse scattering formalism for systems with quasi-zero curvature representations, extending the tools of integrable models to the quasi-integrable setting.
New M87* images with the participation of Gr@v
The Event Horizon Telescope (EHT), a consortium including our group member Hector Olivares, has revealed new detailed images of the supermassive black hole at the center of the galaxy M87 — known as M87* — which show a dynamic environment, with changing polarization patterns near the black hole.

GW250914 - gravitational waves day
On September 14, the Fábrica Centro de Ciência Viva de Aveiro hosted a full-day event dedicated to gravitational waves and gravitation, bringing together audiences of all ages to celebrate science, discovery, and knowledge sharing.
XVIII Black Holes Workshop
The XVIII edition of the Black Holes Workshop will take place at the Instituto Superior Técnico, Lisbon, Portugal, on December 18-19, 2025.
Black hole scalarization with spontaneous symmetry breaking
Spontaneous scalarization of black holes may be understood in the language of symmetry breaking, with the scalar field condensate serving as order parameter. This motivates the study of theories with more interesting symmetry breaking patterns, i.e. beyond the simplest real scalar case.
Science and art in the "Traces of curvature" exhibit
As part of the celebrations marking 10 years of gravitational wave observations, the Aveiro outreach centre Fábrica presents the exhibition Traces of Curvature (Traços de curvatura). This artistic retrospective reflects on the scientific work in strong gravity carried out at the University of Aveiro, which now celebrates its 15th anniversary.
"Shadows of Kerr black holes with scalar hair" reaches 500 cites
The 2015 Gr@v paper "Shadows of Kerr black holes with scalar hair", published in Physical Review Letters (making the cover of the publication issue), has reached 500 citations in the INSPIRE database.
