SVOM [SVOM collaboration]
The SVOM (Space Variable Objects Monitor) satellite observatory is a Chinese-French collaboration dedicated to the study of GRBs (Gamma-Ray Bursts). The mission's goal is to study the most powerful explosions in the universe back to the first generation of stars. SVOM will find hundreds of GRBs that indicate the deaths of massive stars or the merging of two compact stars. In both cases, the explosion produces a black hole or a young magnetar surrounded by a torus of matter that rapidly accretes onto the compact object (in seconds), releasing massive amounts of energy in two transient relativistic jets. When one of the jets is pointed at the Earth, a bright high energy transient followed by a bright low energy transient can be observed.
The satellite carries two wide field high energy instruments:
Two narrow field telescopes that can measure the evolution of the afterglow after a slew of the satellite:
The ground segment also includes additional instrumentation, such as a GWAC (Ground Wide Angle optical Camera) that monitors the field of view of the ECLAIRs in real time during a portion of the orbit, and two 1 m class robotic GFTs (Ground Follow-up Telescopes).
