    The Composition of the Sagittarius Dwarf Spheroidal Galaxy and Implications for Nucleosynthesis and Chemical Evolution

    We have measured the chemical composition of 14 stars in the Sagittarius dwarf spheroidal galaxy (Sgr dSph) using high S/N Keck HIRES echelle spectra. For the Sgr dSph stars with [Fe/H]≥–1 the abundances are h...

    The CNOC Cluster Survey

    The CNOC cluster survey was designed to measure the cluster mass to light ratio and the luminosity density of the Universe in the same range of redshifts for the purpose of estimating the parameter Ω. We find tha...

    Populations in the Z=0.23 Rich Cluster Abell 2390

    We have spectra, colours and morphologies from the CFHT for 240 cluster members and 80 field galaxies over a 7 × 46 arcmin field. The cluster galaxies show strong radial gradients in colour, morphology, and sp...
