Link between magnetars and Fast radio bursts
An international campaign including ground-based and space telescopes, including the INTEGRAL satellite, discovered end of April 2020 very short pulses in both X-rays and radio waves coming from a compact object in the Galaxy, the magnetar SGR 1935+2154.

The discovery of a new type of gravitational wave
Using a range of detectors developed with the participation of the CEA, physicists at CEA-Irfu have scrutinized the region from which the gravitational wave was detected on August 17, 2017 by LIGO-VIRGO facilities.

The INTEGRAL satellite to search for the source of gravitational waves
One instrument of the INTEGRAL satellite that continuously monitors the sky was active at the time of the discovery by the LIGO instrument of the first ever-detected gravitational wave, GW150914, resulting from the merger of two black holes.
