In an idealized Euclid-like simulation forecast, the combined redshift distribution, height distribution, and angular clustering of weak-lensing peaks constrain cosmology better than shear two-point correlation functions; the peak redshift distribution is the single most powerful statistic.

Cosmological constraining power of the redshifts, heights, and angular clustering of weak gravitational lensing peaks
In an idealized Euclid-like simulation forecast, the combined redshift distribution, height distribution, and angular clustering of weak-lensing peaks constrain cosmology better than shear two-point correlation functions; the peak redshift distribution is the single most powerful statistic.
