A preliminary All-sky search of Flaring and transient in the TeV gamma-ray sky observed by HAWC

The long-term operation of HAWC provides valuable opportunities to study transient and variability phenomena in sources emitting at TeV energies. In this work, we introduce the All-sky Root around in an Unbiased way (ARU) algorithm, a tool designed to estimate the significance of deviations from constant emission on different timescales using data from ground-based gamma-ray observatories. We compute the expected sensitivity of ARU for HAWC data.
