"Probing the origins of the Canis Major Overdensity" |
Brian Pohl |
Abstract:
A lively debate has sprung up in the literature over the
origin of the Canis Major overdensity since its discovery in 2004. The
principle combatants being N. F. Martin, arguing that this is evidence
of an in-plane galactic accretion scenario, and Y. Momany who insists
this is due to the galactic warp structure. Although much work is being
done by several people on this topic, this talk will concentrate on the
debate itself and its current status.
