Nonlinear redshift space distortion in halo ellipticity correlations: Analytical model and N-body simulations
Teppei Okumura, Atsushi Taruya, Toshiki Kurita +1
We present an analytic model of nonlinear correlators of galaxy/halo ellipticities in redshift space. The three-dimensional ellipticity field is not affected by the redshift-space…
HYMALAIA: A Hybrid Lagrangian Model for Intrinsic Alignments
Francisco Maion, Raul E. Angulo, Thomas Bakx +3
The intrinsic alignment of galaxies is an important ingredient for modelling weak-lensing measurements, and a potentially valuable cosmological and astrophysical signal. In this pa…
The Intrinsic Alignment of Galaxy Clusters and Impact of Projection Effects
Jingjing Shi, Tomomi Sunayama, Toshiki Kurita +7
Galaxy clusters, being the most massive objects in the Universe, exhibit the strongest alignment with the large-scale structure. However, mis-identification of members due to proje…
Effective Field Theory of Intrinsic Alignments at One Loop Order: a Comparison to Dark Matter Simulations
Thomas Bakx, Toshiki Kurita, Nora Elisa Chisari +2
We test the regime of validity of the effective field theory (EFT) of intrinsic alignments (IA) at the one-loop level by comparing with 3D halo shape statistics in N-body simulatio…
Constraints on anisotropic primordial non-Gaussianity from intrinsic alignments of SDSS-III BOSS galaxies
Toshiki Kurita, Masahiro Takada
We measure the three-dimensional cross-power spectrum of galaxy density and intrinsic alignment (IA) fields for the first time from the spectroscopic and imaging data of SDSS-III B…
