Abstract (from CDS):

We report Hubble Space Telescope/Advanced Camera for Surveys observations of two nearby gas-rich dwarf galaxies: DDO 161 and UGCA 319. Their distances determined via the tip of the red giant branch are 6.03–0.21+0.29 and 5.75 ± 0.18 Mpc, respectively. The galaxies form an isolated pair dynamically well separated from the nearest neighbours: KK 176 (7.28 ± 0.29 Mpc) and NGC 5068 (5.16 ± 0.21 Mpc). All four galaxies have a bulk spatial peculiar velocity towards the Virgo cluster of ∼158 ± 17 km s–1 in the Local Group rest frame and ∼330 km s–1 with respect to the cluster centre.
