Hydro Sims include all effects (except of course for those not included).
Analytic and semi-analytic treatments must be fully calibrated with sims to give a useful phenomenology.

SZ(cuts) will deliver valuable cosmic gastrophysics for sure.
Will it deliver fundamental physics e.g., the dark energy EOS, primordial
non-Gaussianity??? σ8 even?Saturday, January 15, 2011
