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.
Three Gr@v members become faculty
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!

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.
