The large-scale structure of the halo of the Andromeda galaxy II. Hierarchical structure in the Pan-Andromeda Archaeological Survey
Alan W. McConnachie, Rodrigo Ibata, Nicolas Martin +29
The Pan-Andromeda Archaeological Survey is a survey of square degrees centered on the Andromeda (M31) and Triangulum (M33) galaxies that has provided the most extensive pano…
Accretion in action: phase space coherence of stellar debris and globular clusters in Andromeda's South-West Cloud
Dougal Mackey, Geraint Lewis, Michelle Collins +13
A central tenet of the current cosmological paradigm is that galaxies grow over time through the accretion of smaller systems. Here, we present new kinematic measurements near the…
NGC 147, NGC 185 and CassII: a genetic approach to orbital properties, star formation and tidal debris
Veronica Arias, Magda Guglielmo, Nuwanthika Fernando +9
NGC147, NGC185 and CassiopeiaII (CassII) have similar positions in the sky, distances and measured line of sight velocities. This proximity in phase space suggests that these three…
A thousand shadows of Andromeda: rotating planes of satellites in the Millennium-II cosmological simulation
Rodrigo A. Ibata, Neil G. Ibata, Geraint F. Lewis +5
In a recent contribution, Bahl \& Baumgardt investigated the incidence of planar alignments of satellite galaxies in the Millennium-II simulation, and concluded that vast thin plan…
