Pressure auto-power spectrum as a function of redshift in the different panels. For every redshift, we show the power spectrum of Horizon-AGN in a coloured dashed line, the HMx prediction in a coloured full line, the predicted one-halo term in a coloured thin line, and the predicted two-halo term in a coloured dotted-dashed line. We superimpose the pressure auto-power spectrum within (without) one virial radius in a grey full line (grey dotted-dashed line). On the left, we show the result for z = 0.02, on the middle for z = 1.16, and on the right for z = 3.01.
