    An optical fiber system to perform bidimensional spectroscopy
    This article describes a fiber optic system contrived to perform spectral imaging of extended objects. It consists of two fiber bundles mounted simultaneously...

    An Optical Study of a Sample of Spiral Galaxies
    We present the first results of an observational project aimed at producing a database of nearby face-on spiral galaxies in the optical. The project is being...
  • Publication
    An optical supernova associated with the X-ray flash XRF 060218
    Long-duration γ-ray bursts (GRBs) are associated with type Ic supernovae that are more luminous than average and that eject material at very high velocities...

    An optical time-resolved spectroscopic study of SS Cygni. 1: Quiescence
    In this work we analyze time-resolved spectra of SS Cygni in quiescence. The geometrical and orbital fundamental parameters of the system are determined. When...
  • Publication
    An optical time-resolved spectroscopic study of SS Cygni. II. Outburst.
    Time resolved spectra of SS Cyg corresponding to different outburst types are analyzed. Some evidence has been found for an increase of the mass transfer rate...

    An optical transmission spectrum of the giant planet WASP-36 b
    We present broad-band photometry of five transits in the planetary system WASP-36, totalling 17 high-precision light curves. Four of the transits were...
  • Publication
    An 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...
  • Publication
    An optimized Hβ index for disentangling stellar population ages
    We have defined a new Hβ absorption index definition, Hβo, which has been optimized as an age indicator for old and intermediate age stellar populations. Rather...

    An 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...
