Description

The Atacama Cosmology Telescope (ACT) has released its most comprehensive dataset to date: ACT Data Release 6 (DR6). 
This release includes all data collected by the ACT telescope between May 5, 2017, and July 2, 2022. 
For the first time in our field, the release will also provide the complete pipeline required to go from CMB maps to cosmological parameters.
In this talk, I will present the results from ACT DR6 and discuss the challenges we faced in producing the most precise cosmological
maps of CMB polarization to date.
