We present the first characterization of a thick disc component in the Andromeda galaxy (M31) using kinematic data from the DEIMOS multi-object spectrograph in- strument on Keck II. Using 19 fields in the South West of the galaxy, we measure the lag of this component with respect to the thin disc, as well as the dispersion, metallicity and scale length of the component. We find an average lag between the two components of hvi = 45.2 � 4.5kms −1 . The velocity dispersion of the thick disc… Expand
