Abstract

We investigate the nature of WEAK alerts, when the instruments detect an event that falls below the regular significance thresholds. We have initiated rapid follow-up observations of a sample of these alerts using the Swift satellite to allow for a broadband analysis of the alerts. Out of 15 chosen WEAK alert triggers ($approx 4\%$ of the entire WEAK trigger population) we confirm the existence of six GRBs and, additionally, one candidate AGN. We have shown that real high energy events exist within the INTEGRAL WEAK alert population. Future investigations into WEAK alerts could further explore the low fluence regime for explosive transients and give direction for future gamma-ray missions.
