Description
On large scales, peculiar velocities encode a wealth of cosmological information. While line-of-sight components are routinely probed, measuring transverse velocities has remained challenging. I will present a new detection of dipolar patterns associated with transverse velocities, imprinted on the Cosmic Microwave Background through the integrated Sachs–Wolfe effect and gravitational lensing. These new measurements provide new constraints on general relativity.
