Title:
In Search of the Most Distant Supernovae and their Rates
Abstract
For the past decade type Ia supernovae have been instrumental in
measuring the cosmological parameters and in revealing the
accelerating nature of the universe's expansion. And yet, we still do
not know what kind of stellar system is the progenitor of this type of
supernova. In my talk I will present a survey for high redshift
supernovae conducted with the Subaru 8.2m telescope in the Subaru Deep
Field. Using these supernovae, we measure the rates of type Ia
supernovae out to redshift z=2. This type of measurement allows us to
place constraints on the nature of the progenitor system.
