New perspectives on the problem of galaxies without dark matter The discovery of numerous very low surface brightness galaxies in the environment of NGC 1052 provides a crucial clue to the debate about the lack of dark matter in some galaxies of this group. The new data points to the existence of a group of galaxies closer than NGC 1052, to which these anomalous galaxies would belong, and the proximity would solve the problem |
