An almost dark galaxy with the mass of the Small Magellanic Cloud
Almost dark galaxies are objects that have eluded detection by traditional surveys such as the Sloan Digital Sky Survey (SDSS). The low surface brightness of these galaxies (μ r(0) > 26 mag arcsec −2), and hence their low surface stellar mass density (a few solar masses per pc 2 or less), suggest that the energy density released by baryonic
