GRB 030329 and GRB 021211 Detected by HETE-2

The association of Gamma-Ray Bursts (GRBs) with Supernovae (SNe), or at least of some GRBs with some SN is now confirmed for several events. Of these, the most intense and better followed is the one associated with SN2003dh, namely GRB 030329, detected by HETE-2, a NASA ``explorer'' mission devoted to fast detection and localization of GRBs. Other events detected by the same experiment, such as GRB 020813, GRB 021211 and GRB 030723, have been claimed to be associated with SNe. Considering all four events would make HETE-2 the mission which until now detected more SN-associated GRBs than any other one.
