GS model with zero triggered star formation (a0 = c0 = 0) with r1 = 0.001 and β 0 = 2 $ \tilde{\beta}_0 = 2 $ for reasons described in the text. (a) ψGS(z) and (b) ρ*(z) obtained numerically (black solid line) and analytically (green dashed line; Eqs. (54) and (68), respectively). Symbols with error bars are data for ψ(z) and ρ*(z) tabulated by Madau & Dickinson (2014).
