Satellites that are capable of detecting gamma-ray bursts can trigger the ANTARES neutrino telescope via the real-time gamma-ray bursts coordinates network. Thanks to the “all-data-toshore” concept that is implemented in the data acquisition system of ANTARES, the sensitivity to neutrinos from gamma-ray bursts is significantly increased when a gamma-ray burst is detected by these satellites. Th...

The Gamma-Ray Optical Counterpart Search Experiment (GROCSE) presents new experimental upper limits on the optical flux from gamma-ray bursts (GRBs). Our experiment consisted of a fully-automated very wide-field opto-electronic detection system that imaged locations of GRBs within a few seconds of receiving trigger signals provided by BATSE’s real-time burst coordinate distribution network (BAC...

We briefly review the fundamentals of nuclear gamma-ray line astronomy (radioactive astronomy), focusing on its role to decipher the intimate physics of supernovae, either immediatly (via 56 Co) or after a time delay (via 44 T i). All kinds of super-novae can be in principle tested through their radioactivities and their associated gamma-ray lines. Dedicated to the spectroscopy and imaging of c...
