Description
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.
