Prospective Type Ia Supernova Surveys From Dome A

Understand

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 Ia supernova surveys for cosmology.
• A self-contained search and survey over five years can yield a spectro-photometric time series of ~1000 z<0.08 supernovae.
• These can serve to anchor the Hubble diagram and quantify the relationship between luminosities and heterogeneities within the Type Ia supernova class, reducing systematics.
