Beyond power spectrum to unveil systematics on HI intensity maps
Context. H I intensity mapping is a promising technique to probe large-scale structure, traditionally analyzed via two-point statistics such as the angular power spectrum. This latter technique has proven very powerful but may miss key non-Gaussian information present in the signal. Aims. We extend...
