(''Nick writing of behalf of Simone, Emmanuel, and David'')

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 [https://arxiv.org/abs/1308.0847 | 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.

'''QSOs'''

To Do:
Looking into well motivated science requirements for the S4-CDT, which will also guide our SO design. 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.
