Comparing the observable properties of dwarf galaxies on and off the Andromeda plane
Michelle L. M. Collins, Nicolas F. Martin, R. M. Rich +6
The thin, extended planes of satellite galaxies detected around both the Milky Way and Andromeda are not a natural prediction of the LCDM paradigm. Galaxies in these distinct plane…
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…
Spectroscopy of the three distant Andromedan satellites Cassiopeia III, Lacerta I, and Perseus I
Nicolas F. Martin, Kenneth C. Chambers, Michelle L. M. Collins +10
We present Keck II/DEIMOS spectroscopy of the three distant dwarf galaxies of M31 Lacerta I, Cassiopeia III, and Perseus I, recently discovered within the Pan-STARRS1 3πimaging sur…
The PAndAS Field of Streams: stellar structures in the Milky Way halo toward Andromeda and Triangulum
Nicolas F. Martin, Rodrigo A. Ibata, R. Michael Rich +16
We reveal the highly structured nature of the Milky Way stellar halo within the footprint of the PAndAS photometric survey from blue main sequence and main sequence turn-off stars.…
