AQuA: an automatic pipeline for fast transients detection

Abstract

AQuA (Automatic QUick Analysis) is a software designed to manage data reduction and prompt detection of near infra-red (NIR) afterglows of GRB triggered by the dedicated instruments onboard satellites and observed with the robotic telescope REM. NIR observations of GRBs early afterglow are of crucial importance for GRBs science, revealing even optical obscured or high redshift events. The core of the pipeline is an algorithm for automatic transient detection, based on a decision tree that is continuously upgraded through a Bayesian estimator (DecOAR). It assigns to every transient candidate different reliability coefficients and delivers an alert when a transient is found above the reliability threshold.
