Cosmic rate of type IIn supernovae and its evolution with redshift

Type IIn supernovae potentially constitute a large fraction of the gravitationally lensed predicted to be found with upcoming facilities. However, local rate is used for these estimates, which assumed independent properties such as host galaxy mass. Some studies hint that mass bias may exist supernovae. This paper aims provide an updated supernova-to-core-collapse ratio based on data from Palomar Transient Factory (PTF) and Zwicky Facility (ZTF) Bright Survey (BTS). Furthermore, goal investigate dependency supernova peak magnitude consequences possible preference volumetric type We constructed approximately volume-limited subsamples determine ratio. investigated absolute subsample superluminous II or exploring how this relates i-band galaxies (as proxy stellar mass). presented method quantify effect potential low-mass utilizing UniverseMachine algorithm. The ratios PTF BTS are 0.046 +- 0.013 0.048 0.011, respectively, results in 0.047 0.009, consistent 0.05 currently estimate number report fainter median magnitudes brighter than -20.5 mag 3 sigma significance. If were described by power law model $IIn/CC = 0.15 \cdot \log(M/M_{\odot})^{-0.05}$, we would expect slightly elevated redshifts beyond 3.2.
