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…
Hitting the mark: Optimising Marked Power Spectra for Cosmology
Jessica A. Cowell, David Alonso, Jia Liu
Marked power spectra provide a computationally efficient way to extract non-Gaussian information from the matter density field using the usual analysis tools developed for the powe…
Cosmology from HSC Y1 Weak Lensing with Combined Higher-Order Statistics and Simulation-based Inference
Camila P. Novaes, Leander Thiele, Joaquin Armijo +7
We present cosmological constraints from weak lensing with the Subaru Hyper Suprime-Cam (HSC) first-year (Y1) data, using a simulation-based inference (SBI) method. % We explore th…
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…
Impact of baryonic feedback on HSC Y1 weak lensing non-Gaussian statistics
Daniela Grandón, Gabriela A. Marques, Leander Thiele +3
Baryonic feedback is a major systematic in weak lensing cosmology. Its most studied effect is the suppression of the lensing power spectrum, a second-order statistic, on small scal…
