Forecasted halo-y and galaxy-y cross-correlation measurements with DESI, SO and CMB-S4 can tightly constrain group-scale halo pressure profiles and discriminate feedback models.
The first assumes that the galaxy survey is used to identify an underlying population of dark matter halos

Constraining the properties of gaseous halos via cross-correlations of upcoming galaxy surveys and thermal Sunyaev-Zel'dovich maps
Forecasted halo-y and galaxy-y cross-correlation measurements with DESI, SO and CMB-S4 can tightly constrain group-scale halo pressure profiles and discriminate feedback models.
