Former Gr@v member Raimon Luna developed a project to visualize many mathematical and physical concepts through images and animations fully generated by short Python scripts.
Each picture is supposed to introduce a different idea in mathematics or physics in a visually appealing way, without the use of any text or numbers. For those of us who tend to have a visual understanding of these abstract topics, including the author, the pictures can be a nice way to get a different intuition on them.
C. Herdeiro visited Hunan Normal University for two weeks in August-September 2026, where he gave a lecture course on Gravitating Solitons and Hairy Black holes. During the visit it was also possible to interact with collegues from Jianxi Normal University. Many thanks to Mengjie Wang and the whole group at HNU, led by Prof. Jiliang Jing, as well as to Hyat Huang and the whole group in JNU, for a wonderful hosting and great scientific interactions in Changsha and Nanchang.
Gr@v students M. Brito, J. Ferreira and M. Mariano were amongst the participants of the New Frontiers in Strong Gravity meeting in Benasque, in July 2026.
João Novo successfully defended his Ph.D. thesis with title Light rings, shadows and geodesic structure of four and five dimensional spacetimes on July 27th 2026. The Ph.D. committe was composed by Astrid Eichhorn, Volker Perlick, Petya Georgieva, António Morais, Pedro Cunha (co-advisor) and João Matias (president). The thesis was advised by C. Herdeiro. Congratulations João!
Recent investigations into non-vacuum general relativity and parametrized spacetimes have reported viable black hole solutions that admit multiple photon spheres.
"The extreme gravity of astrophysical compact objects", a workshop integrated in the NewFunFiCO network took place in Frankfurt in June 2026. A great atmosphere, a variety of interesting science and lively discussions made a great event. The photo was taken in the rooftop of the venue, the historical building where the Stern-Gerlach experiment was conducted in 1922.
Member of Gr@v H. Olivares participated at the Spanish and Portuguese Relativity Meeting 2026, held in Murcia, Spain, to deliver an invited talk on simulating and observing black hole mimickers.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
