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.

Quantum-gravity effects outside the horizon spark black to white hole tunneling

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.

We examine the images and shadows of thin accretion disks around rotating hairy black holes characterized by two non-trivial, time-periodic scalar fields, whose target space possesses non-flat Gaussian curvature.
Laura Bernard visited us in the beginning of April 2025. Thank you for the visit and seminar Laura!
Zeus Sales Moreira successfully defended his Ph.D. thesis on March 31st 2025, which was advised by C. Herdeiro. The committee was composed by Profs. Darío Nunez, Eugen Radu, Alberto Saa and Gonzalmo Olmo and unanimously praised the excellent work of the candidate. Congratulations Zeus and all the best for the future!
