Fig. 15.— Cosmic flows and the underlying density field from the Wiener Filter analysis. The view and slice are identical to those shown in the previous two figures. White dots locate galaxies from the V8k catalog that lie within the slice. White lines identify streamlines of motion, prominent in this slice toward the Virgo Cluster and then culminating in the region of the Centaurus Cluster. The colors provide a description of the underlying density at SGZ=0 as inferred from the Wiener Filter reconstruction, with a progression from blue in voids to red in the regions of highest density.

A video map of motions in the nearby universe
An international team of researchers, including University of Hawaiʻi at Mānoa astronomer Brent Tully, has mapped the motions of structures of the nearby universe in greater detail than ever before.
