We explore the possibility of performing an HI intensity mapping survey with the South African MeerKAT radio telescope, which is a precursor to the Square Kilometre Array (SKA). We propose to use cross-correlations between the MeerKAT intensity mapping survey and optical galaxy surveys, in order to mitigate systematic effects and produce robust cosmological measurements. Our forecasts show that precise measurements of the HI signal can be made in the near future. These can be used to constrain HI and cosmological parameters across a wide range of redshift.

  1. Forecasts of cosmological constraints from HI intensity mapping with FAST, BINGO & SKA-I

    astro-ph.CO 2019-08 conditional novelty 4.0 of 10

    SKA-I is forecast to give the tightest dark-energy constraints of the three single-dish HI intensity mapping surveys, with combining Planck tightening w0 and wa further.
