<span>Abstract</span><br>
<span></span><br>
<span>I will show new results from the Atacama Cosmology Telescope (ACT), including cosmological constraints and data products from the sixth data release, DR6. Using data gathered from 2017 - 2022, the new maps cover 40% of the microwave sky with 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</span><br>
<span>Planck. I will describe how we use these datasets, along with tracers of large-scale-structure, to probe the fundamental physics of the universe across epochs and scales.</span><br>
