The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. VIII. Preliminary Public Catalog Release
M. Soto, A. Bellini, J. Anderson +14
The Hubble Space Telescope (HST) UV Legacy Survey of Galactic Globular Clusters (GO-13297) has been specifically designed to complement the existing F606W and F814W observations of…
The structure of Andromeda II dwarf spheroidal galaxy
Andrés del Pino, Ewa L. Lokas, Sebastian L. Hidalgo +1
We analyze in detail the spatial distribution and kinematic properties of two different stellar populations in Andromeda II (And II) dwarf spheroidal galaxy. We obtained their deta…
The ISLAndS project II: The Lifetime Star Formation Histories of Six Andromeda dSphs
Evan D. Skillman, Matteo Monelli, Daniel R. Weisz +17
The Initial Star formation and Lifetimes of Andromeda Satellites (ISLAndS) project uses Hubble Space Telescope imaging to study a representative sample of six Andromeda dSph satell…
Rotating stellar populations in the Fornax dSph galaxy
Andrés del Pino, Antonio Aparicio, Sebastian L. Hidalgo +1
We present a novel analysis of the internal kinematics of the Fornax dwarf spheroidal galaxy. Our results are based on the largest sample of spectroscopic data for Fornax stars pre…
Chemical history of isolated dwarf galaxies of the Local Group: I. dSphs: Cetus and Tucana
N. Avila-Vergara, L. Carigi, S. L. Hidalgo +1
For the first time, we obtain chemical evolution models (CEMs) for Tucana and Cetus, two isolated dwarf spheroidal galaxies (dSphs) of the Local Group. The CEMs have been built fro…
The ACS LCID Project XI. On the early time resolution of LG dwarf galaxy SFHs: Comparing the effects of reionization in models with observations
Antonio Aparicio, Sebastian L. Hidalgo, Evan Skillman +10
The analysis of the early star formation history (SFH) of nearby galaxies, obtained from their resolved stellar populations is relevant as a test for cosmological models. However,…
