IFAE participated in the [2021 BIST Conference on Quantum Technologies](https://bist.eu/research/conference-2021/). The main event of took place on Wednesday 3, November 2021. And satellite sessions were organized during the week.

35 new events detected by LIGO and Virgo in their latest observation period bring to 90 the gravitational waves detected so far. The dataset, published today outlines the features of new populations of black holes, the masses of which, together with those of the observed neutron stars, provide clues about how stars live and die, further broadening the horizons of gravitational astronomy.

Oscar Blanch has been re-elected spokesperson of the MAGIC collaboration for 2022.

Adrian Macquet has joined the Gravitational Waves group at IFAE as a PostDoc.
