Horizon singularity, energy conditions and shadows in time-dependent and spherically symmetric spacetime
Visualizing Math and Physics with Python
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.
Visit to Hunan Normal University
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 at Benasque
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 PhD exam
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!
X Amazonian Workshop on Gravity and Analogue Models in Belém
The X Amazonian Workshop on Gravity and Analogue Models took place in Belém, Brazil. Since 2012 these events have gathered the international community on the topic, often with the participation of Gr@v (including the first edition). This edition was also part of the NewFunFiCO network.
From Kerr to Non-Integrable Spacetimes: Extending Ray Tracing Beyond Integrability
Recent investigations into non-vacuum general relativity and parametrized spacetimes have reported viable black hole solutions that admit multiple photon spheres.
