Wigner function shapelets: Symplectic representation of astronomical images
Shun Arai
We extend shapelets for the analysis of astronomical images to be available in a phase space, introducing \textit{Wigner function shapelets}(WFSs). Whereas conventional shapelets e…

Multi-band observation of lensed gravitational waves as a probe of small-mass dark matter halos
Katsuya T. Abe, Shun Arai, Ryoto Inui +3
The gravitational lensing effect of gravitational waves (GWs) has been extensively discussed as a probe of small-mass dark matter halos, which can provide missing information about…

CMB lensing tomography with clustering estimation of lens redshift distributions
Shun Arai, John A. Peacock, Hironao Miyatake +1
We develop a clustering-based redshift estimation approach for CMB lensing tomography, focusing on the kernel function of the lensing galaxies. Within a linear galaxy bias framewor…
