New Member in the GW group
November 9, 2022
Gravitational Waves GroupMonica Seglar-Arroyo is a new postdoc at the GW group with a Juan de la Cierva junior contract.
She got her bachelor form the University of Valencia and obtained her master in Particles, Astroparticles and Relativity from University Grenoble-Alpes. She obtained her PhD from the University of Paris-Saclay, where she worked in very high energy gamma-rays with the H.E.S.S. experiment and CTA, and HAWC, as she passed a year as visitor scholar at Penn State University. For her postdoc, she moved to LAPP (Annecy, France) and joined the Virgo Collaboration, while working with the CTA and LST groups, part time.
Welcome, Monica!

Spain strengthens its participation in major gravitational-wave infrastructures
December 10, 2025
The Spanish Ministry of Science, Innovation and Universities has allocated new funding to Spain’s participation in major international gravitational-wave infrastructures, with the Institut de Física d’Altes Energies (IFAE) designated as the institution through which these contributions will be channelled.

LIGO–Virgo–KAGRA complete their richest gravitational-wave observation run to date
November 18, 2025
The LIGO–Virgo–KAGRA (LVK) Collaboration has announced the completion of O4, the most productive gravitational-wave observation run so far, yielding an unprecedented number of candidate events and high-quality data for the scientific community.

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.
