Shapes and orientations of massive halos in the statistically anisotropic universe
Shogo Masaki, Yurino Mizuguchi, Shohei Saga +1
We investigate how statistical anisotropy (SA) in matter distributions affects the distributions of shapes and orientations of cluster-sized halos, using cosmological -body simu…

First confirmation of anisotropic halo bias from statistically anisotropic matter distributions
Shogo Masaki, Maresuke Shiraishi, Takahiro Nishimichi +2
We confirm for the first time the existence of distinctive halo bias associated with the quadrupolar type of statistical anisotropy (SA) of the linear matter density field using co…

Galaxy-dark matter connection from weak lensing in imaging surveys: Impact of photometric redshift errors
Navin Chaurasiya, Surhud More, Daichi Kashino +2
The uncertainties in photometric redshifts and stellar masses from imaging surveys affect galaxy sample selection, their abundance measurements, as well as the measured weak lensin…
