LIGO, Virgo and KAGRA observed 'second generation' black holes for the first time

October 29, 2025

Researchers from the Institut de Física d’Altes Energies (IFAE), through its Gravitational Waves group, participate in the LIGO–Virgo–KAGRA collaboration that has reported the first observational evidence of candidate second-generation black holes. The analysis of two gravitational-wave signals reveals binary systems with unusual mass ratios and spin configurations, opening a new window on black-hole formation in dense astrophysical environments.
