The contribution from small scales on two-point shear analysis: comparison between power spectrum and correlation function
João Ferri, Elisa G. M. Ferreira, Ryo Terasawa
A known problem in cosmic shear two-point statistics is the apparent inconsistency between analyses performed in harmonic space (power spectrum) and real space (angular correlation…
Impact of Simulation Box Size for Weak Lensing: Replication and Super-Sample Effects
Akira Tokiwa, Adrian E. Bayer, Joaquin Armijo +6
We quantify the bias caused by small simulation box size on weak lensing observables and covariances, considering both replication and super-sample effects for a range of higher-or…
Late-time suppression of structure growth as a solution for the tension
Ryo Terasawa, Masahiro Takada, Toshiki Kurita +1
The value inferred from the Subaru Hyper Suprime-Cam (HSC) Year 3 cosmic shear data, under the assumption of the flat CDM model, is 2-3 lower than that inferred from ob…
Testing small-scale modifications in the primordial power spectrum with Subaru HSC cosmic shear, primary CMB and CMB lensing
Ryo Terasawa, Masahiro Takada, Sunao Sugiyama +1
Different cosmological probes, such as primary cosmic microwave background (CMB) anisotropies, CMB lensing, and cosmic shear, are sensitive to the primordial power spectrum (PPS) o…
On the equivalence between galaxy angular correlation function and power spectrum in constraining primordial non-Gaussianity
Ryo Terasawa, Yue Nan, Masahiro Takada
We investigate the angular power spectrum ( and angular correlation function () of galaxy number density field in the presence of the local-type primordial non-Gauss…
The impact of the redshift-dependent selection effect of halos on the redshift-space power spectrum
Kanmi Nose, Masahiro Takada, Ryo Terasawa
In a wide-area spectroscopic survey of galaxies, it is nearly impossible to obtain a homogeneous sample of galaxies with respect to galaxy properties such as stellar mass and host…
