Dyson, just before the first detection of Gravitational Waves (GWs) by LIGO, raised the question of whether the detection of a single graviton can be achieved with GW strain detectors. If this is possible, then it would be a direct evidence for the quantization of the gravitational field.
Two 3-month grants for M.Sc. holders are open within the project 2024.05617.CERN, "Towards precision tests of ultralight dark matter with imaging and gravitational waves". Applications should be submitted between 13 and 24 October 2025. More info in the attached files and the Euraxess site.
In the last year three Gr@v members obtained faculty positions (as Assistant Professors) in Portuguese Universities: António Morais (Physics Dept., U. Minho), Miguel Zilhão (Physics Dept., U. Aveiro), Pedro Cunha (Mathematics Dept., U. Aveiro). Congratulations to António, Miguel and Pedro for this great achievement!
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.
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:
