We revisit recent claims of a significant detection of a bulk flow of distant galaxy clusters. We do not find a statistically significant detection of a bulk flow. Instead we find that cosmic microwave background correlations between the eight Wilkinson Microwave Anisotropy Probe channels used in this analysis decrease the inferred significance of the detection to 0.7σ.

First measurement of the bulk flow of nearby galaxies using the cosmic microwave background
Peculiar velocities in the nearby Universe can be measured via the kinetic Sunyaev-Zel’dovich (kSZ) eect. Using a statistical method based on an optimised cross-correlation with nearby galaxies, weExpand
The Polarization Signature of Local Bulk Flows
A large peculiar velocity of the intergalactic medium produces a Doppler shift of the cosmic microwave background with a frequency-dependent quadrupole term. This quadrupole will act as a source forExpand
THE ERROR BUDGET OF THE DARK FLOW MEASUREMENT
We analyze the uncertainties and possible systematics associated with the "Dark Flow" measurements using the cumulative Sunyaev-Zeldovich (SZ) effect combined with all-sky catalogs of clusters ofExpand

One Thousand and One Clusters: Measuring the Bulk Flow with the Planck ESZ and X-Ray-selected Galaxy Cluster Catalogs
We present our measurement of the 'bulk flow' using the kinetic Sunyaev-Zel'dovich (kSZ) effect in the Wilkinson Microwave Anisotropy Probe (WMAP) seven-year data. As the tracer of peculiarExpand
Measuring the cosmological bulk flow using the peculiar velocities of supernovae
We study large-scale coherent motion in our universe using the existing Type IA supernovae data. If the recently observed bulk flow is real, then some imprint must be left on supernovae motion. WeExpand
Measuring the Galaxy Cluster Bulk Flow from WMAP data
We have looked for bulk motions of galaxy clusters in the Wilkinson Microwave Anisotropy Probe (WMAP) seven-year data. We isolate the kinetic Sunyaev-Zeldovich (SZ) signal by filtering the WMAP Q-,Expand
Evidence of galaxy cluster motions with the kinematic Sunyaev-Zel'dovich effect.
TLDR
Using high-resolution microwave sky maps made by the Atacama Cosmology Telescope, strong evidence for motions of galaxy clusters and groups via microwave background temperature distortions due to the kinematic Sunyaev-Zel'dovich effect is presented. Expand
