Abstract

The new on-board AGILE MiniCalorimeter -Gravitational Waves(MCAL-GW) configuration increased the detector trigger capabilities for short duration high-energy transients, such as short duration sub-threshold events (STEs), as well as short gamma-ray bursts (GRBs). The aim of this change was the improvement of the satellite trigger logic, to make AGILE more competitive in the detection of possible electromagnetic counterparts to gravitational waves detected by the LIGO/Virgo experiments. At the moment, a new pipeline system has been established, running an automatic search algorithm, aimed at processing the MCAL data, searching for GRB and STE signatures, promptly distributing data to the AGILE Team, for more advanced offline analysis. The new MCAL-GW configuration substantially improved the detection capabilities of MCAL, leading to the detection of 52 GRBs and more than 2 × 104 STEs.
