Discovery of Isolated, Quenched Candidate Backsplash Dwarf Galaxies near M101
Three faint, quiescent dwarf galaxies near M101 were discovered as potential backsplash galaxies stripped from a host system. Their low star formation rates and dSph shapes suggest they were environmentally stripped. This finding helps test the ΛCDM model by providing data for abundance models of ejected satellite populations, relevant for future surveys like LSST.
