Detectability of High-Redshift Superluminous Supernovae with Upcoming Optical and Near-Infrared Surveys - II. Beyond z=6

Understand

Observational identification of the first stars is one of the great challenges in the modern astronomy.

• Although a single first star is too faint to be detected, supernova explosions of the first stars can be bright enough.
• An important question is whether such supernovae can be detected in the limited observational area with realistic observational resources.
• We perform detailed simulations to study the detectability of superluminous supernovae (SLSNe) at high redshifts, using the observationally-calibrated star formation rate density and supernova occurrence rate.
