SNfactory Discovery and Follow-up Simulations

Here is shown the redshift distribution for Type Ia supernovae the SNfactory expects to find using the NEAT dataset. A limiting magnitude of B = 18.7 has been assumed. The central, solid curve corresponds to a "typical" Type Ia with stretch = 1. The other two curves correspond to the redshift distributions for the most overluminous and most unluminous Type Ia supernova. This redshift distribution results from an interplay between the increasing volume element at larger redshifts and the shortened time during which a rising supernova is above the detection threshold. The cut-off redshift corresponds to a Type Ia supernova at peak.
