On June 4th, C. Herdeiro delivered an outreach talk on gravitational waves for nearly one hundred high school teachers in the fabulous space Miguel Torga, near the house where the writer and poet was born, in S. Martinho de Anta, near Vila Real. A fantastic organization by a wonderful group of dedicated teachers!
Our group is co-organizing the VII Amazonian Symposium on Physics, in Belém do Pará, Brazil, 22-26 September 2025, also integrated in the NewFunFiCO network.
Members of the NewFunFiCO network got together in Valencia from 20-22 May 2025 to discuss many aspects related to compact objects and fundamental fields. Truly enjoyable meeting. Thank you to the Valencia group, especially Nico Sanchis-Gual for the great meeting.
In the first half of May 2025, Gr@v hosted many wonderful collegues, including Isabel Cordero (U. Valencia, Spain),
We discuss recent results on using boson stars with a solitonic potential as models of ultracompact objects, which could mimic black holes in such phenomenology as VLBI images and gravitational wave signals.

The study of regular black holes and black hole mimickers as alternatives to standard black holes has recently gained significant attention, driven both by the need to extend general relativity to describe black hole interiors, and by recent advances in observational technologies.
