Abstract

The first supernovae will soon be visible at the edge of the observable universe, revealing the birthplaces of Population III stars. With upcoming near-infrared missions, a broad analysis of the detectability of Population III supernovae is paramount. We combine cosmological and radiation transport simulations, instrument specifications, and survey strategies to create synthetic observations of primeval core-collapse, Type IIn and pair-instability supernovae with the James Webb Space Telescope (JWST). We show that a dedicated observational campaign with the JWST can detect up to $15$ pair-instability explosions, $300$ core-collapse supernovae, but less than one Type IIn explosion per year, depending on the Population III star formation history. Our synthetic survey also shows that $10^2$ supernova detections, properly classified, are sufficient to discriminate between a Salpeter and flat mass distribution for primordial stars with a confidence level greater than 99.5 per cent.
