Description
I will discuss the cosmological constraints from the combination and cross-correlation of radio, optical, and microwave cosmological observations in order to obtain precise measurements of perturbations on large scales.
Specifically I will show that a conservative combination of an SKAO-MID HI intensity mapping survey with the galaxy clustering from two photometric galaxy surveys (Euclid- and LSST-like), and with CMB lensing from CMB-S4, could reach tight uncertainties for primordial non-Gaussianity parameters and total neutrino mass.
