Discs of satellites: the new dwarf spheroidals

Metz, Manuel; Kroupa, Pavel; Jerjen, Helmut


The spatial distributions of the most recently discovered ultra-faint dwarf satellites around the Milky Way and the Andromeda galaxy are compared to the previously reported discs-of-satellites (DoS) of their host galaxies. In our investigation, we pay special attention to the selection bias introduced due to the limited sky coverage of Sloan Digital Sky Survey (SDSS).
