High Redshift Supernova Rates
We use a sample of 42 supernovae detected with the Advanced Camera for Surveys on-board the Hubble Space Telescope as part of the Great Observatories Origins Deep Survey to measure the rate of core collapse supernovae to z ∼ 0.7 and type Ia supernovae to z ∼ 1.6. This significantly increases the redshift range where supernova rates have been estimated from observations. The rate of core collaps...
متن کامل0 Supernova Types and Rates ∗
We review the basic properties of the different supernova types identified in the current taxonomy, with emphasis on the more recent developments. To help orienting in the variegate zoo, the optical photometric and spectroscopic properties of the different supernova types are presented in a number of summary figures. We also report the latest estimates of the supernova rates and stress the need...
متن کاملSupernova rates and stellar populations
We discuss the results about the nature of type Ia Supernovae that can be derived by studying their rates in different stellar populations. While the evolution of SN photometry and spectra can constrain the explosion mechanism, the SN rate depends on the progenitor system. We review the current available data on rates as a function of parent galaxy color, morphology, star formation rate, radio ...
متن کاملThe Evolution of the Cosmic Supernova Rates
Through a combination of deep wideeld imaging and near-IR spectroscopy, the NGST will be able to chart with unprecedented accuracy the evolution of cosmic structures after the `dark ages' (z < 5), when galaxies are thought to assemble and form the bulk of their stars. In particular, accurate measurements at all redshifts of the frequencies of Type II and Ia SNe could be used as a probe of the s...
متن کامل20 05 Supernova Rates in Galaxy Clusters
Measurements of SN rates in different environments and redshifts can shed light on the nature of SN-Ia progenitors, star formation history, and chemical enrichment history. I summarize some recent work by our group in this area, and discuss the implications. The current evidence favors production of most of the iron in the ICM (and perhaps everywhere) by core-collapse SNe, rather than SNe-Ia. T...
