Pairwise Transverse Velocity Measurement with the Rees-Sciama Effect

By Siavash Yasini and others
We introduce a new estimator for the mean pairwise velocities of galaxy clusters, which is based on the measurement of the clusters' \(\textit{transverse}\) velocity components. The Rees-Sciama (RS) effect offers an opportunity to measure transverse peculiar velocities through its distinct dipolar signature around the halo centers in the Cosmic Microwave... Show more
