The SVOM mission, 

a new generation GRB mission

Future GRB studies must rely on the availability of a continuous flow of accurate GRB positions (to take advantage of instrumental progress), but also on the measure of many additional parameters of the GRB (e.g. redshift, E-peak, jet break time, ...) which are crucial for the understanding of the GRBs themselves and for their use as astrophysical tools.

The SVOM mission (Space-based multi-band astronomical Variable Objects Monitor) will:

  • Permit the detection of all known types of GRBs
  • Provide fast, reliable GRB positions
  • Measure the broadband spectral shape of the prompt emission (from visible to MeV)
  • Measure the temporal properties of the prompt emission (from visible to MeV)
  • Quickly identify the afterglows of detected GRBs at X-ray and optical wavelengths, including those which are highly redshifted (z>6)
  • Measure the broadband spectral shape of the early and late afterglow (from visible to X-rays)
  • Measure the temporal evolution of the early and late afterglow (from visible to X-rays)

The mission concept

The constant advances in the field of GRB studies is made possible by the increasing synergy between space and ground instruments. The SVOM mission has been designed to optimize particularly this synergy. The on-board instruments will permit the detection of the GRBs, their localization from arcminutes to arcsecondes accuracy, the study of the prompt emission, the early detection and follow-up of visible afterglows, and the primary selection of high-redshift candidates (z>6). The ground segment will permit the fast distribution of the alerts, the localization of GRBs with sub-arcsecondes precision and the multi-band photometry of the afterglow and the prompt emissions, from the visible to the near-infrared domains. more...
