GRB

The knowledge about GRB (Gamma Ray Burst) is growing.

I try to detect optical counterparts of GRBs announced by the satellites HETE, SWIFT and INTEGRAL. I collabore with the High Energy Network of AAVSO (American Association of Variable Star Observers). Since 2002, 13 optical counterparts were detected from Gnosca. Since some years the observations are discontinued.

Optical Counterparts of GAMMA RAY BURST detected in Gnosca

  • GRB021004  (with optical counterpart detection). Redshift: z = 2.335. Here one can see an  animation. The swiss magazine ORION published this article GRB021004 (pdf in french).
