The Astrophysical Journal Letters, 2023 We report the first constraints on the growth rate of the universe, f ( z ) σ _8 ( z ), with intrinsic alignments (IAs) of galaxies. We measure the galaxy density-intrinsic ellipticity cross-correlation and intrinsic ellipticity autocorrelation functions

Searching For Integrated Sachs-Wolfe Effect Beyond Temperature Anisotropies: CMB E-mode Polarization-Galaxy Cross Correlation [PDF]
, 2005 The cross-correlation between cosmic microwave background (CMB) temperature anisotropies and the large scale structure (LSS) traced by the galaxy distribution, or sources at different wavelengths, is now well known.

The Aemulus Project. V. Cosmological Constraint from Small-scale Clustering of BOSS Galaxies
The Astrophysical Journal, 2023 We analyze clustering measurements of BOSS galaxies using a simulation-based emulator of two-point statistics. We focus on the monopole and quadrupole of the redshift-space correlation function, and the projected correlation function, at scales of 0.1 ...

Searching for a dipole modulation in the large-scale structure of the Universe [PDF]
, 2014 Several statistical anomalies in the CMB temperature anisotropies seem to defy the assumption of a homogeneous and isotropic universe. In particular, a dipole modulation has been detected both in WMAP and Planck data. We adapt the methodology proposed by

Magnetic Fields in the Large-Scale Structure of the Universe [PDF]
, 2011 Magnetic fields appear to be ubiquitous in astrophysical environments. Their existence in the intracluster medium is established through observations of synchrotron emission and Faraday rotation.

The Astrophysical Journal, 2023 The JWST early release data show unexpected high stellar mass densities of massive galaxies at 7 < z < 11. A high star formation efficiency is probably needed to explain this.

CMBPol Mission Concept Study: Gravitational Lensing [PDF]
, 2008 Gravitational lensing of the cosmic microwave background by large-scale structure in the late universe is both a source of cosmological information and a potential contaminant of primordial gravity waves.

Large-scale Filamentary Structure around the Protocluster at Redshift z=3.1 [PDF]
, 2005 We report the discovery of a large-scale coherent filamentary structure of Lyman alpha emitters in a redshift space at z=3.1. We carried out spectroscopic observations to map the three dimensional structure of the belt-like feature of the Lyman alpha ...

The Astrophysical Journal, 2023 The apparent shape of galaxy clustering depends on the adopted cosmology used to convert observed redshift to comoving distance, the r ( z ) relation, as it changes the line elements along and across the line of sight differently.

Effects of massive neutrinos on the large-scale structure of the Universe [PDF]
, 2011 Cosmological neutrinos strongly affect the evolution of the largest structures in the Universe, i.e. galaxies and galaxy clusters. We use large box-size ful l hydrodynamic simulations to investigate the non-linear effects that massive neutrinos ha ve on ...
