Cosmological constraints using Minkowski functionals from the first year data of the Hyper Suprime-Cam
Joaquin Armijo, Gabriela A. Marques, Camila P. Novaes +5
We use Minkowski functionals to analyse weak lensing convergence maps from the first-year data release of the Subaru Hyper Suprime-Cam (HSC-Y1) survey. Minkowski functionals provid…

Stage IV baryonic feedback correction for non-Gaussianity inference
Daniela Grandón, Elena Sellentin
Non-Gaussian statistics of the projected weak lensing field are powerful estimators that can outperform the constraining power of the two-point functions in inferring cosmological…

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…
