I am Research Assistant Professor at Yukawa Institute for Theoretical Physics, Kyoto University
and Invited Researcher at LPENS, Département de Physique, École Normale Supérieure.
My main research interests are in theoretical and observational astrophysics and cosmology.
κTNG: Baryonic effects on WL statistics
Baryonic effect is the major systematic effect in weak lensing surveys. We have generated largest suite of mock weak lensing maps, which is composed of 10,000 realisations. The mock maps cover up to the source redshift 2.6. The sample data is available at Columbia Lensing.
HSC WL and Planck tSZ cross-correlation
The cross-correlation of weak lensing and the thermal Sunyaev-Zel'dovich effect probes the large-scale structures and cluster astrophysics. We measured the cross-correlation with HSC and Planck data, and put constraints on cosmological parameters and mass bias parameter.
