Constraining the CO intensity mapping power spectrum at intermediate redshifts

Understand

We compile available constraints on the carbon monoxide (CO) 1-0 luminosity functions and abundances at redshifts 0-3.

• This is used to develop a data driven halo model for the evolution of the CO galaxy abundances and clustering across intermediate redshifts.
• It is found that the recent constraints from the CO Power Spectrum Survey ($z \sim 3$; Keating et al.
• 2016), when combined with existing observations of local galaxies ($z \sim 0$; Keres et al.
