A distance of 13 Mpc resolves the claimed anomalies of the galaxy
  lacking dark matter
  The claimed detection of a diffuse galaxy lacking dark matter represents a
possible challenge to our understanding of the properties of these galaxies and
galaxy formation in general. The galaxy, already identified in photographic
plates taken in the summer of 1976 at the UK 48-in Schmidt telescope, presents
normal distance-independent properties (e.g. colour, velocity dispersion of its
globular clusters). However, distance-dependent quantities are at odds with
those of other similar galaxies, namely the luminosity function and sizes of
its globular clusters, mass-to-light ratio and dark matter content. Here we
carry out a careful analysis of all extant data and show that they consistently
indicate a much shorter distance (13 Mpc) than previously indicated (20 Mpc).
With this revised distance, the galaxy appears to be a rather ordinary low
surface brightness galaxy (R_e=1.4+-0.1 kpc; M*=6.0+-3.6x10^7 Msun) with plenty
of room for dark matter (the fraction of dark matter inside the half mass
radius is >75% and M_halo/M*>20) corresponding to a minimum halo mass >10^9
Msun. At 13 Mpc, the luminosity and structural properties of the globular
clusters around the object are the same as those found in other galaxies.
