Dipolar power asymmetry in wide-angle correlations of galaxy density, velocity and ellipticity
Yusuke Mikura, Teppei Okumura, Ippei Obata +1
The large-scale structure of the universe has the potential to probe anomalies suggested by observations of the cosmic microwave background. In this work, we focus on a position-de…
Constraining Primordial Power Asymmetry from Galaxy Clustering and Peculiar Velocity Information
Keita Minato, Atsushi Taruya, Teppei Okumura +1
Primordial power asymmetry would probe departures from statistical isotropy, offering a clue to the physics of the primordial Universe. We investigate how such asymmetries can be t…
Parity-violating scalar trispectrum from helical primordial magnetic fields
Kaito Yura, Shohei Saga, Maresuke Shiraishi +1
Some recent observations of the cosmic microwave background (CMB) anisotropies and the large-scale structure of the Universe imply cosmic parity violation. Among possible parity-vi…
Probing dipolar power asymmetry with galaxy clustering and intrinsic alignments
Keita Minato, Atsushi Taruya, Teppei Okumura +1
We investigate the prospects for probing large-scale statistical anisotropy through galaxy clustering and intrinsic alignments (IA) in Stage IV galaxy surveys. Specifically, we con…
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…
Non-Gaussianity Beyond the Scalar Sector: A Search for Tensor and Mixed Tensor-Scalar Bispectra with Planck Data
Oliver H. E. Philcox, Maresuke Shiraishi
Primordial gravitational waves could be non-Gaussian, just like primordial scalar perturbations. Although the tensor two-point function has thus-far remained elusive, the three-poi…
