Constrain the high-redshift volumetric rate of Type I superluminous supernovae

Constrain the volumetric rate of Type I superluminous supernovae at high redshift, where the scarcity of detections currently prevents reliable rate estimates.

Background

The predicted rate of strongly lensed SLSN-I discoveries depends directly on the intrinsic volumetric rate of SLSNe-I. The paper emphasizes that measurements at higher redshifts are based on sparse detections, making the rate model a major source of uncertainty in the predicted ZTF and future-survey yields.

References

Consequently, the volumetric rate of SLSNe-I remains poorly constrained at higher redshifts, where detections are sparse.
