The Atacama Cosmology Telescope: Systematic Transient Search of Single Observation Maps

Understand

We conduct a systematic search for astrophysical transients using data from the Atacama Cosmology Telescope (ACT).

• The data were taken from 2017 to 2022 in three frequency bands spanning 77 GHz to 277 GHz.
• In this paper we present a pipeline for transient detection using single observation maps where each pixel of a map contains one observation with an integration time of approximately four minutes.
• We detect 34 transient events at 27 unique locations.
