ABSTRACT
Very massive Population III stars explode as pair-instability supernovae (PI SNe), the most energetic thermonuclear explosions in the universe with energies 100 times those of Type Ia and Type II SNe. Their extreme luminosities may allow them to be discovered at the era of first light, unveiling the character of primordial stars and the primitive galaxies in which they reside. We present numerical simulations of Pop III PI SNe and light curves done with the LANL RAGE and SPECTRUM codes. Our calculations show that 150 - 250 M⊙ PI SNe will be visible to the James Webb Space Telescope (JWST) out to z ∼ 30 and to z ∼ 15 - 20 in all-sky NIR surveys by the Wide Field Infrared Survey Telescope (WFIRST). We also show preliminary light curves for ultraluminous Pop III Type IIn SNe, which may be visible out to z ∼ 10 - 15 in future optical and NIR surveys.
