A Multi-Wavelength Study of the Segue 3 Cluster
Joanne Hughes, Brianna Lacy, Charli Sakari +7
We present new SDSS and Washington photometry of the young, outer-halo stellar system, Segue 3. Combined with archival VI-observations, our most consistent results yield: …
Photometric Metallicities in Bootes I
J. Hughes, G. Wallerstein, A. Dotter +1
We present new Stromgren and Washington data sets for the Bootes I dwarf galaxy, and combine them with the available SDSS photometry. The goal of this project is to refine a ground…
Determining Photometric Metallicities of dSph Stellar Populations
Joanne Hughes, George Wallerstein
If there are so few upper red-giant branch stars in the SDSS-discovered dwarf galaxies, how can we find the true population structure without extensive spectroscopy? We review rece…
The Age and Metallicity of the Bootes I System
Joanne Hughes, George Wallerstein, Anne Bossi
We present Washington photometry of a field central to the Bootes I dwarf spheroidal galaxy, which was discovered as a stellar overdensity in the Sloan Digital Sky Survey (DR5). We…
Photometric Observations of Omega Centauri: Multi-Wavelength Observations of Evolved Stars
Joanne Hughes, George Wallerstein, Floor van Leeuwen
We present multi-wavelength observations of the northern population of Omega Cen from the main-sequence turn-off to high on the red giant branch. We show that the best information…
Age and Metallicity Effects in Omega Centauri
Joanne Hughes, George Wallerstein
We have observed (with vby filters) a field north of the core of the most massive globular cluster in our galaxy, Omega Centauri. We have found a correlation of age and metallicity…
