Predictions of Early Cosmic Structure Formation





Baryon Phases and the early IMF : Maio and Péroux (2026)

SFRD evolution for top-heavy and Salpeter PopIII IMF, varying initial conditions, and different volumes and resolutions:
data - ColdSIM CDM reference
data - top-heavy PopIII CDM
data - top-heavy PopIII WDM
data - top-heavy PopIII, Gaussian fnl=0, large volume
data - top-heavy PopIII, non-Gaussian fnl=100, large volume
data - top-heavy PopIII, 60 km/s bulk velocity, high resolution
data - ColdSIM CDM large volume
data - Salpeter PopIII, Gaussian fnl=0, large volume
data - Salpeter PopIII, non-Gaussian fnl=100, large volume
data - top-heavy PopIII, Gaussian fnl=0, high resolution
data - top-heavy PopIII, non-Gaussian fnl=100, high resolution
