Cosmology News & Events

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.

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. 

Our group is co-organizing the X Amazonian Workshop on Gravity and Analogue Models from 29 June to 3 July in Belém, Brazil. More info here.

The NewFunFiCO network is organizing a workshop in Frankfurt from 15-17 June 2026. More info here. 

Oleg Tsupko, an expert in several strong gravity topics including lensing and black hole shadows, joins Gr@v as a CEEC researcher from April 2026. Welcome Oleg!

The Gr@v coordinator, C. Herdeiro, visited Prague to deliver two seminars, at CEICO and Charles University. The visit provided a great opportunity to reconnect with friends and colleagues in a city rich in scientific and cultural heritage - home to figures such as Kepler, Tycho Brahe, Einstein, Doppler, Mach, Bolzano, and Kafka. Many thanks to both groups for their kind hospitality and for making this visit possible.

In January-February we received the visits of Andrea Maselli (Grand Sasso, Italy), Gabriel Ribeiro (UFPA, Brazil) and Juan José Vázquez (INAOE, Mexico). Knowledge transfer in action!

Our friend and collaborator Haroldo Junior visited Aveiro for a few weeks in February 2026. A former PhD student in Belém/Aveiro and now a faculty member at Universidade Federal do Maranhão in São Luís, it was a pleasure to have him back. In the photo, Haroldo is joined by our very esteemed secretary, Cristina.

In the last week of January 2026, a research school on black holes and related topics took place in the beautiful setting of Licán Ray, Chile, nestled in a stunning volcanic lake region. C. Herdeiro was among the invited lecturers, with sessions held - quite fittingly - on whiteboards set up in the garden. The combination of great science and a relaxed, inspiring atmosphere made for a truly memorable event. Many thanks to Adolfo Cisterna and his team for making it all possible.
