Synergy of CO/[CII]/Lyα Line Intensity Mapping with the SKA

Abstract

This subchapter describes the science enabled by cross-correlations of the SKA1-LOW 21-cm EoR surveys with other line mapping programs. In particular, we identify and investigate potential synergies with planned programs, such as the line intensity mapping of redshifted CO rotational lines, [CII] and Lyα emissions during reionization. We briefly describe how these tracers of the star-formation rate at z ~ 8 can be modeled jointly before forecasting their auto-and cross-power spectra measurements with the nominal 21cm EoR survey. After discussing the measurement prospect, we discuss how reionization parameters can be better constrained using these new measurements.
