New Search for Dark Matter Free Dwarf Galaxies using Legacy Imaging

Studies of ultra-diffuse galaxies (UDGs) NGC 1052 DF2 and DF4, in addition to the more recent study of FCC 224, confirm little to no dark matter content in these galaxies, an unprecedented discovery which remains controversial due to the challenges it poses to the currently understood galaxy formation models. These well-studied dark matter free UDGs share a pattern of hosting overly-luminous, monochromatic globular clusters; believed to be closely connected to the formation of these galaxies. By parameterizing these globular clusters, a method was developed to guide a search for new dark matter free candidates. The search is still ongoing, though the search method has been developed and one interesting candidate has been found already.
