HI Intensity Mapping with MeerKAT
  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.
