"Illuminating the Physical Processes of Galaxy Evolution with the Cosmic Microwave Background"

Abstract: A new window into the growth and evolution of large-scale structure has opened up with the recent observations of the thermal and kinetic Sunyaev-Zel’dovich (SZ) effects. I will review recent observations of the SZ signals and highlight their expected rapid growth over the next decade with upcoming cosmic microwave background experiments, like Simons Observatory and CMB-S4. I will present ongoing work to extract SZ signals in data from the Atacama Cosmology Telescope and how they can be used to constrain the important baryonic processes that govern galaxy formation. I will conclude by showing the tension between these new SZ observations and state-of-the-art cosmological simulations and discuss the prospects for future constraints.
