摘要

Dome A, the highest plateau in Antarctica, is being developed as a site for an astronomical observatory. The planned telescopes and instrumentation and the unique site characteristics are conducive toward Type la supernova surveys for cosmology. A self-contained search and survey over 5 years can yield a spectro-photometric time series of similar to 1000z < 0.08 supernovae. These can serve to anchor the Hubble diagram and quantify the relationship between luminosities and heterogeneities within the Type la supernova class, reducing systematics. Larger aperture (greater than or similar to 4-m) telescopes are capable of discovering supernovae shortly after explosion out to z similar to 3. These can be fed to space telescopes, and can isolate systematics and extend the redshift range over which we measure the expansion history of the universe.
