Parallel T01 - Astroparticles, Gravitation and Cosmology T01

Description

In March 2025, the Atacama Cosmology Telescope (ACT) released its last cosmological analysis along with a new cosmic microwave background (CMB) dataset. The sixth data release (DR6), including data collected from 2017 to 2022, covers 40% of the sky at arcminute resolution providing the most precise maps of CMB temperature and polarization. In this talk, I will give an overview of the ACT DR6 analysis and describe its constraints on fundamental assumptions of the standard cosmological model and extensions to it, including constraints on particle physics.
