Speaker: Alexander van Engelen, CITA, University of Toronto
Subject: Lensing and Other Results from ACTPol

Surveys of the CMB from ground-based observatories have revealed much about cosmology, in particular by measuring effects on CMB photons since recombination. In this talk, I will summarize results from the ongoing ACTPol survey, highlighting in particular the measurement of gravitational lensing by matter between us and the CMB recombination surface. I will discuss challenges with these measurements and also look forward to what will be possible with upcoming surveys such as SPT-3G, AdvACT, and CMB-S4.
