Description
The Atacama Cosmology Telescope (ACT) was a ground-based CMB experiment in the Atacama desert in Chile that observed the millimeter sky between 2008 and 2022 at frequencies ranging from 90 GHz to 220 GHz with three detector arrays. The combination of the ~arcminute angular resolution, large footprint, and high cadence of the experiment made the instrument an excellent tool for millimeter time-domain science. We now have an initial catalog of ACT light curves containing the ~200 brightest active galactic nuclei (AGN) in its data, sampled over several years. In this talk we will describe how we are using these light curves for multiwavelength cross-correlation with optical and gamma-ray light curves. Cross-correlating emission in these different bands can aid in understanding which of the leptonic or hadronic processes is most often responsible for emission in the two components of the blazar SED, and the relative locations of the emission regions for different wavebands.
