The kinematic identification of a thick stellar disc in M31
M. L. M. Collins, S. C. Chapman, R. A. Ibata +6
We present the first characterization of a thick disc component in the Andromeda galaxy (M31) using kinematic data from the DEIMOS multi-object spectrograph instrument on Keck II.…
Dwarf spheroidals in the M81 Group - Metallicity distribution functions and population gradients
Sophia Lianou, Eva K. Grebel, Andreas Koch
We study the dwarf spheroidal galaxies in the nearby M81 group in order to construct their photometric metallicity distributions and to investigate the potential presence of popula…
A close look at the Centaurus A group of galaxies: I. Metallicity distribution functions and population gradients in early-type dwarfs
D. Crnojević, E. K. Grebel, A. Koch
We study dwarf galaxies in the Centaurus A group to investigate their metallicity and possible environmental effects. The Centaurus A group (at ~4 Mpc from the Milky Way) contains…
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…
