Detecting cosmic structure via 21-cm intensity mapping on the Australian Telescope Compact Array.

Abstract (from CDS):

The studies of the nature of dark energy have defined contemporary astrophysics. We report the first detection of a cosmic power spectrum using the Australian Telescope Compact Array interferometer in the 21-cm L-band. We obtained the power spectrum through cross-correlation with optical galaxies, as well as auto-correlation using radio data alone.
