Cosmological constraints from weak lensing scattering transform using HSC Y1 data
Sihao Cheng, Gabriela A. Marques, Daniela Grandón +4
As weak lensing surveys go deeper, there is an increasing need for reliable characterization of non-Gaussian structures at small angular scales. Here we present the first cosmologi…
