A Sparse Spectroscopic Supernova Survey
arXiv:2107.02187
Abstract
Supernova cosmology surveys are traditionally time consuming, especially for the critical spectroscopic data. However, a single spectrum at maximum light may provide accurate distance estimation if recent developments hold. This could open up a new type of supernova cosmology survey, with a useful interaction between the spectra and a focus on specific redshifts. We optimize the redshift selection and show that this condensed survey could efficiently deliver highly accurate dark energy constraints.
