Mapping systematic errors in helium abundance determinations using Markov Chain Monte Carlo
Erik Aver, Keith A. Olive, Evan D. Skillman
Monte Carlo techniques have been used to evaluate the statistical and systematic uncertainties in the helium abundances derived from extragalactic H~II regions. The helium abundanc…
The ACS LCID project. VI. The SFH of the Tucana dSph and the relative ages of the isolated dSph galaxies
M. Monelli, C. Gallart, S. L. Hidalgo +10
We present a detailed study of the star formation history (SFH) of the Tucana dwarf spheroidal galaxy. High quality, deep HST/ACS data, allowed us to obtain the deepest color-magni…
The evolution of stellar structures in dwarf galaxies
N. Bastian, D. R. Weisz, E. D. Skillman +8
We present a study of the variation of spatial structure of stellar populations within dwarf galaxies as a function of the population age. We use deep Hubble Space Telescope/Advanc…
The ACS Nearby Galaxy Survey Treasury IX. Constraining asymptotic giant branch evolution with old metal-poor galaxies
Leo Girardi, Benjamin F. Williams, Karoline M. Gilbert +10
In an attempt to constrain evolutionary models of the asymptotic giant branch (AGB) phase at the limit of low masses and low metallicities, we have examined the luminosity function…
The Nature of Starbursts : II. The Duration of Starbursts in Dwarf Galaxies
Kristen B. W. McQuinn, Evan D. Skillman, John M. Cannon +7
The starburst phenomenon can shape the evolution of the host galaxy and the surrounding intergalactic medium. The extent of the evolutionary impact is partly determined by the dura…
Spatially Resolved PAH Emission Features in Nearby, Low Metallicity, Star-Forming Galaxies
Korey Haynes, John M. Cannon, Evan D. Skillman +2
Low-resolution, mid-infrared Spitzer/IRS spectral maps are presented for three nearby, low-metallicity dwarf galaxies (NGC 55, NGC 3109 and IC 5152) for the purpose of examining th…
