Tidal Dwarf Galaxies Bonn 2009: Ghosts from structure formation
Affiliation: Argelander-Institut für Astronomie
Title: The Local Group satellite galaxies: are they ancient tidal dwarfs?
Date: Friday 29th May
Time: 12:45 - 13:15
Presentation file: talk_Kroupa.pdf
The satellite galaxies of the Milky Way, and to a less-significant amount, those of Andromeda, are distributed anisotropically about their hosts. The MW system appears to be a disk-like feature which is rotating. These features of the satellite galaxy distribution indicate that many of the satellites may be ancient tidal-dwarf galaxies. If true this would have possibly major implications for fundamental physics.
