Particle initialization effects on Lyman- forest statistics in cosmological SPH simulations
Nabendu Kumar Khan, Girish Kulkarni, James S. Bolton +4
Confronting measurements of the Lyman- forest with cosmological hydrodynamical simulations has produced stringent constraints on models of particle dark matter and the thermal a…
