DESCRIPTION:Recent observations have shown that Ultra-Diffuse Galaxies (UD
 Gs\, which have the luminosities of dwarfs but sizes of giant galaxies) ar
 e surprisingly abundant in local clusters of galaxies. The origin of UDGs 
 remains unclear\, as the interpretation of these studies has been hindered
  by the (partly) subjective selection of these galaxies\, and the limited 
 study of only the Coma and Virgo clusters. I’ll present results of the f
 irst systematic search for UDGs in eight nearby clusters. I’ll focus on 
 the abundance of UDGs as a function of halo mass\, and their radial distri
 bution in the clusters. The latter indicates that they were likely accrete
 d by the cluster several Gyrs ago\, but are still hosted by massive dark-m
 atter haloes. I’ll discuss implications and future prospects to learn mo
 re about their formation history and properties.
