Machine-learning applications for weak-lensing cosmology

Masato Shirasaki

This article reviews recent advances in the application of machine learning to weak-lensing cosmology. Weak gravitational lensing provides a unique and powerful probe of the total…

Cross-correlating galaxies and cosmic dispersion measures: Constraints on the gas-to-halo mass relation from 2MASS galaxies and 133 localized fast radio bursts

Masato Shirasaki, Ryuichi Takahashi, Ken Osato +1

We conduct a cross-correlation analysis between large-scale structures traced by the Two Micron All Sky Survey (2MASS) galaxy catalog and the cosmic dispersion measures of 133 loca…

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…

Measurement of angular cross-correlation between the cosmological dispersion measure and the thermal Sunyaev--Zeldovich effect

Ryuichi Takahashi, Kunihito Ioka, Masato Shirasaki +1

The dispersion measures () from fast radio bursts (FRBs) and the thermal Sunyaev--Zeldovich (tSZ) effect probe the free-electron density and thermal pressure, respective…

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…

Neural style transfer of weak lensing mass maps

Masato Shirasaki, Shiro Ikeda

We propose a new generative model of projected cosmic mass density maps inferred from weak gravitational lensing observations of distant galaxies (weak lensing mass maps). We const…
