tSZ power spectrum for existing models in the literature. The NILC-MILCA F/L cross-power spectrum after foreground correction (black dots) is compared to the Atacama Cosmology Telescope (ACT; cyan dot) and the South Pole Telescope (SPT; orange, George et al. 2015) power spectrum estimates. We also show the tSZ power spectrum models from hydrodynamic simulations (Battaglia et al. 2012, blue), from N-body simulations plus semi-analytical dust and gas models (Trac et al. 2011, cyan; TBO2), and from analytical calculations (Shaw et al. 2010, green).
