On October 9, 2022, at 13:16 and 59.99 seconds, a gamma-ray burst (GRB) dazzled almost all the X-ray and gamma ray detectors available at the time.

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.

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.

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.

Analysis of the high-energy emission from the microquasar V404 Cygni has lead to the discovery of gusts of electron and positron (the electron anti-particle) plasma.

The X-ray astronomy satellite Astro-H was successfully launched on 17 February 2016  at 17H 45 (UT 8H45) from the JAXA Tanegashima Space Center in Japan. The satellite was put into orbit 14 min later and the first tests started.

Prototype of the X-ray binary systems harboring a black hole, Cygnus X-1 is the subject of many studies since its discovery in the 1960s.

The central black hole of the Galaxy, today surprisingly quiet, has undergone, several hundred years ago, a violent phase of activity.
