An overmassive dark halo around an ultra-diffuse galaxy in the virgo cluster
Ultra diffuse galaxies (UDGs) have the sizes of giant galaxies but the luminosities of dwarfs. A key to understanding their origins comes from their total masses, but their low surface brightnesses ($\mu(V) \geq$ 25.0) generally prohibit dynamical studies. Here we report the first such measurements...
