Beyond power spectrum to unveil systematics on HI intensity maps
Starlet l1-norm applied to simulated HI brightness temperature maps at z~0.4 yields almost 3x higher figure of merit for cosmological parameters than angular power spectrum by capturing non-Gaussian information and shows robustness to observational systematics.
