Pair-instability supernovae (PISNe) have crucial implications for many astrophysical topics,
including the search for very massive stars, the black hole mass spectrum, and galaxy
chemical enrichment. To this end, we need to understand where PISNe are across cosmic
time, and what are their favourable galactic environments. We present a new determination
of the PISN rate as a function of redshift, obtained by combining up-to-date stellar evolution
tracks from the parsec and franec codes, with an up-to-date semi-empirical determination of …
