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. I will also discuss new ways of using upcoming CMB polarization data to constrain primordial non-Gaussianities.
The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
