DESCRIPTION:Speakers: Yan-Cuan Cai (University of Edimburgh)\n\nOn large s
 cales\, peculiar velocities encode rich cosmological information. While th
 e line-of-sight components are routinely analysed through redshift-space d
 istortions and the kinetic Sunyaev-Zel’dovich effect\, measurement of t
 ransverse velocities has remained challenging. I will present a detection 
 of gravitational dipoles aligned with transverse velocities on scales of t
 ens of degrees on the sky\, traced through their imprints on the Cosmic Mi
 crowave Background via the effects of integrated Sachs-Wolfe and CMB lensi
 ng. I will show how this can be used to study cosmology and test general r
 elativity.\n \nRelated work: https://arxiv.org/pdf/2504.02525\n\nhttps://
