Our CMB Motion: The Role of the Local Void
Abstract
A database with a high density of accurate distances is used to investigate the contributions to the motion of our Galaxy. It is found that the motion of the Local Group separates remarkably cleanly into 3 components: a large-scale attraction toward structure in the `Great Attractor' sector, a mid-scale attraction toward the Virgo Cluster, and a local-scale `repulsion' from the Local Void. These 3 components cause motions of comparable amplitudes and, conveniently, are directed almost orthogonal to one another.
