PublicaciónAn empirical approach to the location of the theoretical isochrones in the observational plane
A new empirical calibration of the (B-V) index versus the three fundamental stellar parameters T(eff), (Fe/H), and log g is presented whose range of validity is...

PublicaciónAn old, metal-poor globular cluster in Sextans A and the metallicity floor of globular cluster systems
We report the confirmation of an old, metal-poor globular cluster (GC) in the nearby dwarf irregular galaxy Sextans A, the first GC known in this galaxy. The...

PublicaciónAn Optical-Near-IR Study of a Triplet of Super Star Clusters in the Starburst Core of M82
We present HST/STIS optical and Gemini/NIFS near-IR IFU spectroscopy and archival Hubble Space Telescope (HST) imaging of the triplet of super star clusters (A1...

PublicaciónAn Overmassive Dark Halo around an Ultra-diffuse Galaxy in the Virgo Cluster
Ultra-diffuse galaxies (UDGs) have the sizes of giants but the luminosities of dwarfs. A key to understanding their origins comes from their total masses, but...

PublicaciónAnalysis and calibration of CaII triplet spectroscopy of red giant branch stars from VLT/FLAMES observations
We demonstrate that low-resolution CaII triplet (CaT) spectroscopic estimates of the overall metallicity ([Fe/H]) of individual red giant branch (RGB) stars in...

PublicaciónAssessing the Stellar Population and the Environment of an H II Region on the Far Side of the Galaxy
We have investigated the stellar and interstellar content of the distant star formation region IRAS 17591-2228 (WISE H II region GAL 007.47+0.06). It is...
