Farewell to Etevaldo and visit of Hryhorii Ovcharenko
We got together on May 20th 2026 at Etevaldo's favourite restaurant in Aveiro (O Telheiro), to celebrate his 4.5 years in Gr@v. In the same day we had an excellent seminar from Hryhorii Ovcharenko, visiting from Prague. Etevaldo is now starting a post-doctoral position in Brazil. Many thanks, Etevaldo, for being with us. See you soon!
Celebrating Etevaldo's thesis with guests
In early May 2026 we received the visits of our collaborators Nico Sanchis Gual, Isa Cordero, Gabriele Palloni, Claudio Lazarte (Valencia, Spain), members of the NewFunFiCO network, as well as Carolina Benone (UFPA, Brazil) and Carlos Joaquin (UNAM, Mexico), who joined us to celebrate the successful Ph.D. exam of Etevaldo Costa.
Etevaldo Costa defendes his PhD thesis
Etevaldo Costa successfully defended his Ph.D. thesis with title "Bosonic exotic compact objects: construction and physical properties". The thesis was supervised by C. Herdeiro and E. Radu and the committee included Eric Gourgoulhon, Daniela Doneva and Carolina Benone as examiners. Congratulations Etevaldo!
Visits Maryem Jemri and Justin Feng
In April 2026 we received the visits of Maryem Jemri (Rabat) and Justin Feng (Prague). Thank you for your seminars and the great scientific interactions!

Geometric Cosmology—and in particular Geometric Inflation (GI)—provides a higher-curvature mechanism capable of producing an accelerated expansion in the early Universe without invoking an inflaton in its minimal realization.
Visits Yasha Shnir and Mario Navarro
Gr@v is hosting the visits of Yasha Shnir, long time group collaborator, under an FCT mobility grant, and Mario Luciano Navarro, Ph.D. student from Valencia in the spring 2026. In the photo Yasha and Mario enjoy a bit of sunshine after the weekly group lunch.
