Full Sky Map of Bright Quasars

Full-sky map of all measurements of the fine-structure constant along the line of sight of bright quasars, in early 2019. Overall there is a 3.5 sigma statistical preference for a dipolar spatial variation. The preferred direction of maximal variation is inside the solid red line, and the dashed blue line depicts the equator of the dipole.
