Fascinating read, I did a bit of research on these kinds of supernova back in 2014 when doing my Masters on how metallicity affected the evolution of globular clusters in the early universe. I wasn’t aware that any supernova had been flagged for this since the first stellar epoch! Waiting for JWST to officially discover supernova from the first epoch; out of the detection of Hubble.
VERY low metallicity in the early universe tended towards larger, hotter and faster burning stars. This means a higher chance of pair-instability supernova but also the formation of more larger blackholes to feed the early galaxies. As metallicity increases the average stellar mass decreases as does temperate at the same stellar size due to “impurities” (metals).
What an interest time on which we live
