Overview of the structure surrounding the Local Void. Isosurfaces of density are inferred from the velocity field constructed from the Wiener Filter treatment of Cosmicflows distances, with the densest peaks in red and less dense filaments in gray. The Milky Way is at the origin of the colored arrows, 5000 km s−1 in length, oriented in the frame of supergalactic coordinates (red toward +SGX, green toward +SGY, blue toward +SGZ). The Local Void fills the empty region above the Milky Way in this plot. This view inward from a location at positive values of SGX, SGY, and SGZ will be referred to as the reference orientation.
