Triaxiality can explain the alleged dark matter deficiency in some dwarf
  galaxies
  Dark Matter (DM) is an ingredient essential to the current cosmological
concordance model. It provides the gravitational pull needed for the baryons to
form galaxies. Therefore, the existence of galaxies without DM is both
disquieting and extremely interesting. Guo et al. recently presented "further
evidence for a population of DM-deficient dwarf galaxies", however, their
analysis bypasses the triaxiality of the dwarf galaxies. We carry out a Monte
Carlo simulation showing how triaxiality must be considered to measure
dynamical masses from projected axial ratios, calling into question the
evidence for a population of DM-deficient dwarf galaxies. Such a population may
consist of normal almost face-on HI disks with their inclination overestimated.
