Dissecting the Red Sequence--I. Star Formation Histories of Quiescent Galaxies: The Color-Magnitude vs. the Color-Sigma Relation
Genevieve J. Graves, S. M. Faber, Ricardo P. Schiavon
We use a sample of ~16,000 non-emission line galaxies from the SDSS to investigate the physical parameters underlying the well-known color-magnitude and color-sigma relations. Gala…
Star Clusters in M31: I. A Catalog and a Study of the Young Clusters
Nelson Caldwell, Paul Harding, Heather Morrison +3
We present an updated catalog of 1300 objects in the field of M31, including 670 likely star clusters of various types. Archival images were inspected to confirm cluster classifica…
APOGEE: The Apache Point Observatory Galactic Evolution Experiment
C. Allende Prieto, S. R. Majewski, R. Schiavon +8
APOGEE is a large-scale, NIR, high-resolution (R~20,000) spectroscopic survey of Galactic stars. It is one of the four experiments in SDSS-III. Because APOGEE will observe in the H…
Abundance variations in the globular cluster M71 (NGC 6838)
A. Alves-Brito, R. P. Schiavon, B. Castilho +1
Abundance variations in moderately metal-rich globular clusters can give clues about the formation and chemical enrichment of globular clusters. CN, CH, Na, Mg and Al indices in sp…
Measuring Ages and Elemental Abundances from Unresolved Stellar Populations: Fe, Mg, C, N, and Ca
Genevieve J. Graves, Ricardo P. Schiavon
We present a method for determining mean light-weighted ages and abundances of Fe, Mg, C, N, and Ca, from medium resolution spectroscopy of unresolved stellar populations. The meth…
Ages and Abundances of Red Sequence Galaxies as a Function of LINER Emission Line Strength
Genevieve J. Graves, Sandra M. Faber, Ricardo P. Schiavon +1
Although the spectrum of a prototypical early-type galaxy is assumed to lack emission lines, a substantial fraction (likely as high as 30%) of nearby red sequence galaxy spectra co…
