It is to be launched in 2024. - -\todo[inline]{To be completed} - +SVOM (Space-based multi-band astronomical Variable Objects Monitor) \footnote{https://www.svom.eu/en/home/} +is a Sino-French mission dedicated +to the study of the transient high-energy sky, and in particular to the detection, localization and +study of Gamma Ray Bursts (GRBs). +Gamma-ray bursts are sudden, intense flashes of X-ray and gamma-ray light. +They are associated with the cataclysmic formation of black holes, either by the merger of two compact stars +(neutron star or black hole) or by the sudden explosion of a massive star, twenty to one hundred times the mass of our Sun. +The birth of a black hole is accompanied by the ejection of jets of matter that reach speeds close to the speed of light. +These jets of matter then decelerate in the circumstellar medium, sweeping away everything in their path. +Gamma-ray bursts can be observed at the very edge of the universe, acting as lighthouses that illuminate +the dark ages of its creation. Although they have been studied extensively over the past fifteen years, +gamma-ray bursts are still poorly understood phenomena. To better understand them, China and France have decided +to join forces with the SVOM satellite, which is specifically dedicated to the study of gamma-ray bursts. + +The special feature of the SVOM mission is that it combines ground-based and space-based observations, +providing a spectral bandwidth from the visible to the high-energy range. By guaranteeing multi-wavelength +observations of about one hundred bursts of all types per year, the SVOM mission will make a unique contribution +to two of the most fruitful areas of research in recent decades: the use of bursts in cosmology and the understanding +of the phenomenon. Looking further ahead, the SVOM mission will work in close synergy with a new generation of +instruments dedicated to the search for neutrinos and gravitational waves of cosmic origin, in order to confirm +the astrophysical origin of the signals detected by these future instruments. + +SVOM has been successfully launched on June 22 2024 from Xichang lauchpad. \subsection{KM3Net and neutrino detection}
