Description
The Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) delivers some of the most precise small-scale measurements of the cosmic microwave background, requiring accurate treatment of astrophysical foregrounds at millimeter wavelengths. In this talk, we will present the DR6 parametric foreground model, which accounts for Galactic dust, extragalactic sources, and secondary CMB anisotropies. We detail several tests to validate the capability of the DR6 parametric foreground model to describe current observations and complex simulations, and show that cosmological parameter constraints are robust against model extensions and variations.
