Denoising weak lensing mass maps with diffusion model: systematic comparison with generative adversarial network
Shohei D. Aoyama, Ken Osato, Masato Shirasaki
Removing the shape noise from the observed weak lensing field, i.e., denoising, enhances the potential of WL by accessing information at small scales where the shape noise dominate…

Denoising weak lensing mass maps with diffusion model and generative adversarial network
Shohei D. Aoyama, Ken Osato, Masato Shirasaki
The matter distribution of the Universe can be mapped through the weak gravitational lensing (WL) effect: small distortions of the shapes of distant galaxies, which reflects the in…
