Chemical constraints on the contribution of Population III stars to cosmic reionization
Girish Kulkarni, Joseph F. Hennawi, Emmanuel Rollinde +1
Recent studies have highlighted that galaxies at z = 6-8 fall short of producing enough ionizing photons to reionize the IGM, and suggest that Population III stars could resolve th…

Chemical enrichment of Damped Lyman Alpha systems as a direct constraint on Population III star formation
Girish Kulkarni, Emmanuel Rollinde, Joseph F. Hennawi +1
Damped Ly-alpha absorbers (DLAs) can be used to measure gas-phase metallicities at large cosmological lookback times with high precision. Relative abundances can still be measured…
