New group members
Romain Gervalle (Ph.D. U. Tours, France, 2025) and TianXiang Ma (M.Sc, Lanzhou U., China, 2024) have joined our group in October 2025. Ana Bokulic (Ph.D. U. Zagreb, Croatia, 2024), already a group member, also renewed her group membership into 2026. Great to have you in the group!
Visit of João Dinis Álvares
On Oct. 22nd 2025 we had the visit of João Dinis Álvares, who completed his M.Sc. at IST-Lisbon. João gave an interesting talk on the evolution of scalar fields around black holes and also shared with us that he decided to study physics after an outreach talk by Gr@v members, in Braga, back in 2017. Thank you João, for the kind words and all the best for your Ph.D. abroad!
CERN workshop
On Thursday Oct 23rd, CERN organizes a topical meeting on "New Bosons from Astrophysical sources @ LHC: the case of boson stars". C. Herdeiro is one of the invited speakers.
Two grants for M.Sc. holders
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!
John Ioannidis standardized citation indicators
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.
Meeting in Belém, Brazil
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.
Contribution to "Oscilador Armónico"
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.
