Angular momentum in the Sculptor group.

WHITING A.B.

Abstract (from CDS):

The spins of the major galaxies in the nearby Sculptor Group agree with those calculated to be produced by tidal interactions among themselves. The agreement is closer than would be expected from published uncertainties in distances, indicating either that these uncertainties are smaller than calculated or that they are correlated. Three pairs of galaxies (NGC 55 and 300, 247 and 253, and 45 and 7793) are in approximate two-body orbits; the direction of orbital angular momentum for the first two pairs is derived.
