Unbiased Cosmological Parameter Estimation from Emission-line Surveys with Interlopers
Unbiased Cosmological Parameter Estimation from Emission-line Surveys with Interlopers
The galaxy catalogs generated from low-resolution emission line surveys often contain both foreground and background interlopers due to line misidentification, which can bias the cosmological parameter estimation. In this paper, we present a method for correcting the interloper bias by using the joint-analysis of auto- and cross-power spectra of the …
