The distance and motion of the Maffei Group.

Abstract (from CDS):

It has recently been suggested that the nearby galaxies Maffei 1 and 2 are farther in distance than previously thought, such that they no longer are members of the same galaxy group as IC 342. We reanalyze near-infrared photometry from the Hubble Space Telescope, and find a distance to Maffei 2 of 5.73 ± 0.40 Mpc. With this distance, the Maffei Group lies 2.5 Mpc behind the IC 342 Group and has a peculiar velocity toward the Local Group of -128 ± 33 km s–1. The negative peculiar velocities of both of these distinct galaxy groups are likely the manifestation of void expansion from the direction of Perseus-Pisces.
