Searches for Population III pair-instability supernovae: Predictions for ULTIMATE-Subaru and WFIRST

Understand

ULTIMATE-Subaru (Ultra-wide Laser Tomographic Imager and MOS with AO for Transcendent Exploration on Subaru) and WFIRST (Wide Field Infra-Red Survey Telescope) are the next generation near-infrared instruments that have a large field-of-view.

• They allow us to conduct deep and wide transient surveys in near-infrared.
• Such a near-infrared transient survey enables us to find very distant supernovae that are redshifted to the near-infrared wavelengths.
• We have performed the mock transient surveys with ULTIMATE-Subaru and WFIRST to investigate their ability to discover Population III pair-instability supernovae.
