Abstract: We revisit calculations of nebular hydrogen Lyα and HeII λ1640 line strengths for population III galaxies, undergoing continuous and bursts of star formation. We focus on initial mass functions (IMFs) motivated by recent theoretical studies, which generally span a lower range of stellar masses than earlier works. We also account for case-B departures and the stochastic sampling of the IMF. In agreement with previous works, we find that departures from case-B can enhance the Lyα flux by a factor of a few, but w… Show more
