Double Feature: “SZ with AGN” and “The Cosmology Large Angular Scale Surveyor”

Part 1: Evidence is mounting that Active Galactic Nuclei (AGN) are responsible for the lack of star-formation in the most massive galaxies. Attention has been drawn to the role of energetic radio-mode feedback from the AGN in heating the gas around massive halos and preventing star-formation. I will present the first systematic measurement using the Sunyaev-Zel’dovich (SZ) effect of the pressure of the gas around radio-loud AGN.

 

Part 2: The Cosmology Large Angular Scale Surveyor (CLASS) is a project to measure the imprint of gravitational waves from inflation in the polarization of the cosmic microwave background. I will present an overview of the CLASS strategy for measuring the E-modes and B-modes from both recombination and reionization and give an update on the project status.
