The annual global study led by John Ioannidis (Stanford University, USA), based on Elsevier’s Scopus citation data for 2024, ranked the world’s most influential scientists. The list includes 3 from Gr@v: P. Cunha, C. Herdeiro and E. Radu. See here the U. Aveiro coverage.
The VII Amazonian Symposium in Physics took place in the week of Sep. 23rd 2025. Another stimulating meeting with great talks and scientific interaction. Thank you to all participants and Prof. Luis Crispino for his leadership.
Listen here to the contribution of C. Herdeiro to the spanish podcast "Oscilador Armónico", chating with Isabel Cordero Carrión and António Rivera Nebot about black holes and exotic compact objects (in spanish).
We present the Einstein-Maxwell-Klein-Gordon system in hyperboloidal slices, a recent formulation for extracting signals at future null infinity. As far as we know, this is the first time this setup is evolved with a common formulation like BSSN/Z4. Using hyperboloidal slices, contrary to other recent methods like Cauchy-Characteristic Matching, we can continuously reach future null infinity.
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.
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.

Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
