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…

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…
