The Complex Chemical Abundances and Evolution of the Sagittarius Dwarf Spheroidal Galaxy
Tammy A. Smecker-Hane, Andrew McWilliam
We report on the chemical abundances derived from high-dispersion spectra of 14 red giant stars in the Sagittarius dwarf spheroidal (Sgr dSph) galaxy. The stars span a wide range o…
The Ca II Triplet as an Abundance Indicator
T. Bosler, T. Smecker-Hane, A. McWilliam
How can we accurately determine the metallicity of faint red giant stars in nearby galaxies? The equivalent widths of the broad absorption lines from Ca II at 8498, 8542, and 8662…
Chemical Abundances in the Carina dSph Galaxy
Tammy A. Smecker-Hane, Georgi I. Mandushev, James E. Hesser +3
We report on the chemical abundances of stars in the Carina dwarf spheroidal galaxy (dSph) derived from low-resolution spectra. We have determined values of [Fe/H] for 52 stars fro…
Ages and Chemical Abundances in Dwarf Spheroidal Galaxies
Tammy Smecker-Hane, Andrew McWilliam
The dwarf spheroidal galaxies (dSphs) in the Local Group are excellent systems on which we can test theories of galaxy formation and evolution. Color-magnitude diagrams (CMDs) cont…
The Omega_M-Omega_Lambda Constraint from CNOC Clusters
R. G. Carlberg, H. K. C. Yee, E. Ellingson +14
The CNOC redshift survey of galaxy clusters measures Omega_M from Omega_e(z)= M/L x j/ρ_c which can be applied on a cluster-by-cluster basis. The mass-to-light ratios, M/L, are est…
Omega_M and the CNOC Surveys
R. G. Carlberg, H. K. C. Yee, H. Lin +15
The CNOC1 cluster survey measures Omega_M via Oort's method, Omega_M= M/L x j/rho_c, where M/L is the field mass-to-light ratio, j is the field luminosity density and rho_c is the…
