New Cosmology Results and Maps from ACT DR6

The Atacama Cosmology Telescope (ACT) collaboration presents cosmological constraints and data products from its sixth data release, DR6. Including data from 2017 - 2022 (the telescope decommissioning), DR6 observed 40% of the microwave sky to five times the angular resolution and three times the depth in polarization as the Planck satellite. The improved cosmic microwave background (CMB) measurements at small scales complement the larger-scale information from Planck. We use these datasets, along with tracers of large-scale-structure, to probe the fundamental physics of the Universe across epochs and scales. We release DR6 maps in three frequency bands (located around 90, 150, and 220 GHz) as well as CMB power spectrum likelihoods.
