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 …

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 simulations. This …

Understanding the nonlinear relation between the shapes of halos or galaxies and the
surrounding matter distribution is essential in accurate modeling of their intrinsic alignments …

As well as the galaxy number density and peculiar velocity, the galaxy intrinsic alignment
can be used to test the cosmic isotropy. We study distinctive impacts of the isotropy breaking …

We investigate the alignment of galaxy and halo orientations using the TNG300-1
hydrodynamical simulation. Our analysis reveals that the distribution of the 2D misalignment …

The baryon acoustic oscillation feature in the clustering of galaxies or quasars provides a
'standard ruler'for distance measurements in cosmology. In this work, we report a 2–3 σ …

We formulate the Lagrangian perturbation theory of galaxy intrinsic alignments and compute
the resulting auto and cross power spectra of galaxy shapes, densities and matter to 1-loop …

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 distortion …

The intrinsic alignment of galaxies is an important ingredient for modelling weak-lensing
measurements, and a potentially valuable cosmological and astrophysical signal. In this …

Primordial magnetic fields (PMFs) are one of the plausible candidates for the origin of the
observed large-scale magnetic fields. While many proposals have been made for the …
