Synergies of Large Scale Structure Surveys with CMB-S4, Simone Ferraro, Chihway Chang, and Risa Wechsler
We will focus on the synergies of combining tracers of large scale structure as measured at radio through X-ray wavelengths with the wide-field CMB-S4 survey, which will cover ~70% of the sky. We are particularly interested in exploring cosmological analyses that can only be done via the combination of multi-wavelength probes or that are significantly improved through the use of multiple probes (e.g., Nx2 pt, kSZ cosmology, CMB lensing tomography, cosmic shear/WL calibration, cluster cosmology, etc).
