稀疏光谱超新星巡天

A Sparse Spectroscopic Supernova Survey

Eric V. Linder

摘要:

超新星宇宙学调查传统上是耗时的,特别是对于关键的光谱数据。然而,如果最近的发展保持不变,在最大光下的单一光谱可以提供准确的距离估计。这可能会开辟一种新型的超新星宇宙学调查,光谱之间的有用相互作用和对特定红移的关注。我们优化了红移的选择,并表明这种凝聚的调查可以有效地提供高度准确的暗能量的限制。

英文摘要:

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.
