We predict the amplitude of the gravitational redshift of galaxies in galaxy clusters using an N-body simulation of a ΛCDM universe. We examine the possibility of detecting the gravitational effect on the total redshift observed for galaxies. For clusters of mass M ~ 1015 h-1 M☉, the difference in gravitational redshift between the brightest galaxy and the rest of the cluster members is ~10 km s- 1. The most efficient way to detect gravitational redshifts using information from galaxies only… 
Gravitational redshifts from large-scale structure
The recent measurement of the gravitational redshifts of galaxies in galaxy clusters by Wojtak et al. has opened a new observational window on dark matter and modified gravity. By stacking clusters
N-body simulations of gravitational redshifts and other relativistic distortions of galaxy clustering
Large redshift surveys of galaxies and clusters are providing the first opportunities to search for distortions in the observed pattern of large-scale structure due to such effects as gravitational
Local gravitational redshifts can bias cosmological measurements
Measurements of cosmological parameters via the distance-redshift relation usually rely on models that assume a homogenous universe. It is commonly presumed that the large-scale structure evident in
Comparing gravitational redshifts of SDSS galaxy clusters with the magnified redshift enhancement of background BOSS galaxies
A clean measurement of the evolution of the galaxy cluster mass function can significantly improve our understanding of cosmology from the rapid growth of cluster masses below z < 0.5. Here we
New Interpretation for the Observed Cosmological Redshifts and its Implications
The cosmological redshifts z in the frequencies of spectral lines from distant galaxies as compared with their values observed in terrestrial laboratories, which are due to the scale factor a(t),
Gravitational redshift in galaxy clusters with photometric surveys
I will investigate whether it is possible to detect gravitational redshift in galaxy clusters using photometric data, and if this is possible with the Large Synoptic Survey Telescope (LSST). This is
Relativistic distortions in the large-scale clustering of SDSS-III BOSS CMASS galaxies
General relativistic effects have long been predicted to subtly influence the observed large-scale structure of the universe. The current generation of galaxy redshift surveys have reached a size
Measuring gravitational redshifts in galaxy clusters
Wojtak {\it et al} have stacked 7,800 clusters from the SDSS survey in redshift space. They find a small net blue-shift for the cluster galaxies relative to the brightest cluster galaxies, which
Relativistic effects on galaxy redshift samples due to target selection
In a galaxy redshift survey the objects to be targeted for spectra are selected from a photometrically observed sample. The observed magnitudes and colours of galaxies in this parent sample will be
Gravitational redshift and asymmetric redshift-space distortions for stacked clusters
We derive the expression for the observed redshift in the weak field limit in the observer's past light cone, including all relativistic terms up to second order in velocity. We then apply it to

Cosmological N-body simulations predict that dark matter halos should have a universal shape characterized by a steep, cuspy inner profile. Here we report on a spectroscopic study of six clusters

A Universal Density Profile from Hierarchical Clustering
We use high-resolution N-body simulations to study the equilibrium density profiles of dark matter halos in hierarchically clustering universes. We find that all such profiles have the same shape,

We have attempted to detect non-equilibrium motions in the cores of elliptical galaxies by separating radial velocity profiles into their odd and even components, the latter being zero in equilibrium

We determine the linear amplitude of mass fluctuations in the universe, σ8, from the abundance of massive clusters at redshifts z = 0.5-0.8. The evolution of massive clusters depends exponentially on
