We forecasted S/N and constraints on feedback and non-thermal pressure support for samples of LRGs and QSOs using combined tSZ and kSZ observations and a DESI-like spectroscopic. Here we use the the numbers density of objects quoted in | Table 3 of the DESI white paper.
LRGs
Epsilon is the feedback efficiency, and alpha is the normalization of the non-thermal pressure support. Also, Blue = 4m, Green = 5m, Red = 6m. The orange box illustrates a 3% constraint on these parameters.
QSOs
The orange box illustrates a 25% constraint on these parameters.
To Do: Looking into well motivated science requirements for the S4-CDT. One idea is to couple these constraints to the baryonic effects on p(k), this is k dependent but we should be able to decide on a k range and accuracy to which we need to constrain feedback etc. Any other ideas would be very helpful.
