HI intensity mapping with MeerKAT: power spectrum detection in cross-correlation with WiggleZ galaxies

Exciting news for MeerKAT intensity mapping! We presented a detection of correlated clustering between MeerKAT radio intensity maps and galaxies from the WiggleZ Dark Energy Survey. This detection is the first practical demonstration of the multi-dish auto-correlation intensity mapping technique for cosmology. This marks an important milestone in the roadmap for the cosmology science case with the SKA Observatory.

The paper has been posted on the arXiv and was led by our previous team member Steve Cunnington (now in Manchester University).
