New faint ultra-diffuse dwarf galaxy discovered
An international team of astronomers reports the detection of a new faint ultra-diffuse dwarf galaxy as part of a systematic wide-area search for faint dwarf galaxies using the Dark Energy Survey (DES). The newfound object, designated NGC 55-dw1, is a satellite of the galaxy NGC 55. The finding was detailed in a paper published September 8 on the pre-print server arXiv.
