Variable stars in the field of the Hydra II ultra-faint dwarf galaxy
A. Katherina Vivas, Knut Olsen, Robert Blum +12
We report the discovery of one RR Lyrae star in the ultra--faint satellite galaxy Hydra II based on time series photometry in the g, r and i bands obtained with the Dark Energy Cam…
Recovering star formation histories: Integrated-light analyses vs stellar colour-magnitude diagrams
T. Ruiz-Lara, I. Pérez, C. Gallart +12
Accurate star formation histories (SFHs) of galaxies are fundamental for understanding the build-up of their stellar content. However, the most accurate SFHs - those obtained from…
Variable Stars in Local Group Galaxies. I: Tracing the Early Chemical Enrichment and Radial Gradients in the Sculptor dSph with RR Lyrae Stars
C. E. Martínez-Vázquez, M. Monelli, G. Bono +7
We identified and characterized the largest (536) RR Lyrae (RRL) sample in a Milky Way dSph satellite (Sculptor) based on optical photometry data collected over 24 years. The…
The ACS LCID Project: On the origin of dwarf galaxy types: a manifestation of the halo assembly bias?
C. Gallart, M. Monelli, L. Mayer +13
We discuss how knowledge of the whole evolutionary history of dwarf galaxies, including details on the early star formation events, can provide insight on the origin of the differe…
Evidence for temporal evolution in the M33 disc as traced by its star clusters
Michael A. Beasley, Izaskun San Roman, Carme Gallart +2
We present precision radial velocities and stellar population parameters for 77 star clusters in the Local Group galaxy M33. Our GTC and WHT observations sample both young, massive…
