Using a set of high resolution simulations, we quantify the effect of species-specific initial transfer functions on probes of the intergalactic medium (IGM) via the Lyman-α forest. We focus on redshifts 2–6, after Hireionization. We explore the effect of these initial conditions on measures of the thermal state of the low density IGM: the curvature, Doppler width cutoff, and Doppler width distribution. We also examine the matter and flux power spectrum, and potential consequences for constraints on warm dark matter models. We find that the curvature statistic is at most affected at thelevel atz= 6. The Doppler width cutoff parameters are affected byfor the intercept, andfor the fit slope, though this is subdominant to sample variation. The Doppler width distribution shows aeffect atz= 3, however the distribution is not fully converged with simulation box size and resolution. The flux power spectrum is at most affected byat high redshift and small scales. We discuss numerical convergence with simulation parameters.
