  • Kinematic and Chemical constraints on the formation of M31's inner and outer halo 

    Koch, A., R. M. Rich, D. B. Reitzel, N. F. Martin, et al. 2007. "Kinematic and Chemical constraints on the formation of M31's inner and outer halo." The Astrophysical Journal 689 (2):958
    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 calcium triplet region of over 3500 red ...
