IfA Deep SN rates
Listed in IVOA Registry (Virtual Observatory)
The IfA Deep Survey uncovered ~130 thermonuclear supernova (TN SN, i.e., Type Ia) candidates at redshifts from z=0.1 out to beyond z=1.
Description
The TN SN explosion rates derived from these data have been controversial, conflicting with evidence emerging from other surveys. This work revisits the IfA Deep Survey to re-evaluate the photometric evidence.
Applying the SOFT (Supernova Ontology with Fuzzy Templates) program to the light curves of all SN candidates, we derive new classification grades and redshift estimates. We find a volumetric rate for z~0.5 that is substantially smaller than the originally published values, bringing the revised IfA Deep rate into good agreement with other surveys. With our improved photometric analysis techniques, we are able to confidently extend the rate measurements to higher redshifts and we find a steadily increasing TN SN rate, with no indication of a peak out to z=1.05.
