TL;DR: Evidence of the gravitational lensing of the cosmic microwave background by 10(13) solar mass dark matter halos is presented to demonstrate the potential of microwave background lensing to probe the dark matter distribution in galaxy group and galaxy cluster halos.

TL;DR: In this article, a catalog of 4195 optically confirmed galaxy clusters detected with signal-to-noise ratio >4 in 13,211 deg2 of sky surveyed by the Atacama Cosmology Telescope (ACT) is presented.

TL;DR: In this article, a measurement of the gravitational lensing of the Cosmic Microwave Background (CMB) temperature and polarization fields obtained by cross-correlating the reconstructed convergence signal from the first season of Atacama Cosmology Telescope Polarimeter data at 146 GHz with CIB fluctuations measured using the Planck satellite is presented.

TL;DR: In this article, the first searches using CMB polarization for correlations induced by a possible non-trivial topology with a fundamental domain that intersects or nearly intersects, the last-scattering surface were performed via a direct scan for matched circular patterns at the intersections and by an optimal likelihood calculation for specific topologies.

TL;DR: In this article, the temperature and polarization angular power spectra of the CMB measured by the Atacama Cosmology Telescope (ACT) from 5400 deg$^2$ of the 2013-2016 survey were presented.
