The kinematic footprints of five stellar streams in Andromeda's halo
S. C. Chapman, R. Ibata, M. Irwin +12
(abridged) We present a spectroscopic analysis of five stellar streams (`A', `B', `Cr', `Cp' and `D') as well as the extended star cluster, EC4, which lies within streamC, all disc…
The structural properties and star formation history of Leo T from deep LBT photometry
J. T. A. de Jong, J. Harris, M. G. Coleman +15
We present deep, wide-field g and r photometry of the transition type dwarf galaxy Leo T, obtained with the blue arm of the Large Binocular Telescope. The data confirm the presence…
Kinematic and Chemical constraints on the formation of M31's inner and outer halo
A. Koch, R. M. Rich, D. B. Reitzel +8
The halo of M31 shows a wealth of substructures that are consistent with satellite accretion. Here we report on kinematic and abundance results from Keck/DEIMOS spectroscopy in the…
The core of the Canis Major galaxy as traced by Red Clump stars
M. Bellazzini, R. Ibata, N. Martin +3
The recently-discovered stellar system in Canis Major is analysed using He-burning Red Clump stars as tracers. Canis Major turns out to be the strongest and most spatially confined…
The Canis Major Dwarf Galaxy
Geraint F. Lewis, Rodrigo A. Ibata, Michael J. Irwin +3
Recent observational evidence suggests that the Sagittarius dwarf galaxy represents the only major ongoing accretion event in the Galactic halo, accounting for the majority of stel…
A dwarf galaxy remnant in Canis Major: the fossil of an in-plane accretion onto the Milky Way
N. F. Martin, R. A. Ibata, M. Bellazzini +3
We present an analysis of the asymmetries in the population of Galactic M-giant stars present in the 2MASS All Sky catalogue. Several large-scale asymmetries are detected, the most…
