The Alignment of Dark Matter Halos with the Cosmic Web
We investigate the orientation of the axes and angular momentum of dark matter halos with respect to their neighboring voids using high-resolution N-body...
The APOSTLE simulations: solutions to the Local Group's cosmic puzzles
The Local Group galaxies offer some of the most discriminating tests of models of cosmic structure formation. For example, observations of the Milky Way (MW)...
The Aquila comparison project: the effects of feedback and numerical methods on simulations of galaxy formation
We compare the results of various cosmological gas-dynamical codes used to simulate the formation of a galaxy in the Λ cold dark matter structure formation...
The Araucaria Project: A Wide-Field Photometric Survey for Cepheid Variables in NGC 3109
We have obtained mosaic images of NGC 3109 in the V and I bands on 74 nights, spanning approximately 1 yr. From these data, we have conducted an extensive...
The Arcminute Microkelvin Imager is a pair of interferometer arrays operating with six frequency channels spanning 13.9-18.2GHz, for observations on angular...
We study the formation of 53 galaxy cluster-size dark matter halos (M = 1014.0-14.76 M sun) formed within a pair of cosmological Λ cold dark matter N-body...
The Atacama Cosmology Telescope: A Catalog of >4000 Sunyaev–Zel’dovich Galaxy Clusters
We present a catalog of 4195 optically confirmed Sunyaev–Zel’dovich (SZ) selected galaxy clusters detected with signal-to-noise ratio >4 in 13,211 deg 2 of sky...
The Baryon Oscillation Spectroscopic Survey of SDSS-III
The Baryon Oscillation Spectroscopic Survey (BOSS) is designed to measure the scale of baryon acoustic oscillations (BAO) in the clustering of matter over a...
The Bias from Hydrodynamic Simulations: Mapping Baryon Physics onto Dark Matter Fields
This paper investigates the hierarchy of baryon physics assembly bias relations obtained from state-of-the-art hydrodynamic simulations with respect to the...
