摘要

Observational identification of the first stars is one of the greatchallenges in the modern astronomy. Although a single first star is too faintto be detected, supernova explosions of the first stars can be bright enough.An important question is whether such supernovae can be detected in the limitedobservational area with realistic observational resources. We perform detailedsimulations to study the detectability of superluminous supernovae (SLSNe) athigh redshifts, using the observationally-calibrated star formation ratedensity and supernova occurrence rate. We show that a 100 deg^2 survey with thelimiting magnitude of 26 mag in near-infrared wavelengths will be able todiscover about 10 SLSNe at z > 10. If the survey is extended to 200 deg^2 with27 mag depth, about 10 SLSNe can be discovered at z > 15. We emphasize that theobservations at > 3 um are crucial to detect and select SLSNe at z > 10. Oursimulations are also applied to the planned survey with Euclid, WFIRST, andWISH. These surveys will be able to detect about 1000, 400, and 3000 SLSNe upto z ~ 5, 7, and 12, respectively. We conclude that detection of SLSNe at z >10 is in fact achievable in the near future.
