This paper presents detailed analysis of large-scale peculiar motions derived from a sample of ~700 X-ray clusters and cosmic microwave background (CMB) data obtained with WMAP. We use the kinematic Sunyaev-Zeldovich (KSZ) effect combining it into a cumulative statistic that preserves the bulk motion component with the noise integrated down. Such statistic is the dipole of CMB temperature fluctuations evaluated over the pixels of the cluster catalog. To remove the cosmological CMB fluctuations… Expand

TLDR
A new method for measuring the possible large-scale bulk flows in the universe from the cosmic microwave background (CMB) maps from the upcoming missions of the Microwave Anistropy Probe (MAP) and Planck is proposed and it is found that at the 95% confidence level, the bulk flows can be probed down to the amplitude of less than 200 km s(-1) with the MAP data and down to only approximately 30 km s-1 with the Planck mission.
