Galaxy disruption in a halo of dark matter
journal contribution
posted on 2024-07-11, 10:22 authored by Duncan ForbesDuncan Forbes, Michael A. Beasley, Kenji Bekki, Jean BrodieJean Brodie, Jay StraderThe relics of disrupted satellite galaxies have been found around the Milky Way and Andromeda, but direct evidence of a satellite galaxy in the early stages of disruption has remained elusive. We have discovered a dwarf satellite galaxy in the process of being torn apart by gravitational tidal forces as it merges with a larger galaxy's dark matter halo. Our results illustrate the morphological transformation of dwarf galaxies by tidal interaction and the continued buildup of galaxy halos.
