Description
I will present the detection of Gpc-scale dipoles in gravitational potentials in the large-scale structure of the Universe. Large-scale transverse peculiar velocities are used as signposts and correlated with CMB temperature maps and gravitational lensing maps, revealing dipoles on angular scales of tens of degrees. I will also present constraints on general relativity derived from these new observables.
