When we talk about the science we can extract from the CMB, we often focus on the the imprint of the standard lambda CDM parameters on the power spectrum. However, as these CMB photons have carved a path through the universe, they’ve picked up subtle imprints of the clusters of galaxies in their path. Two of these effects – thermal and kinetic Sunyaev–Zeldovich effects – offer probes of the universe’s largest scale structure all the way to the time when the CMB was first formed. In this MASS talk we will go over what these effects are, how we measure them, and the kind of fundamental physics they can reveal.
