    A MUSE study of the fast bar in the weakly-interacting galaxy NGC 4264
    We present surface photometry and stellar kinematics of NGC 4264, a lenticular galaxy in the region of the Virgo Cluster undergoing a tidal interaction with its...
  • Publication
    A Near-infrared Census of the Multicomponent Stellar Structure of Early-type Dwarf Galaxies in the Virgo Cluster
    The fraction of star-forming to quiescent dwarf galaxies varies from almost infinity in the field to zero in the centers of rich galaxy clusters. What is...
  • Publication
    A near-infrared study of the multiphase outflow in the type-2 quasar J1509+0434
    Based on new near-infrared spectroscopic data from the instrument Espectrógrafo Multiobjeto Infra-Rojo (EMIR) on the 10.4 m Gran Telescopio Canarias, we report...
  • Publication
    A near-IR study of the host galaxies of 2 Jy radio sources at 0.03 <~ z <~ 0.5 - I. The data
    We present the results of a program of K- and KS-band imaging of a sample of 2Jy radio galaxies with redshifts 0.03
  • Publication
    A near/mid infrared search for ultra-bright submillimetre galaxies: Searching for Cosmic Eyelash Analogues
    We present results from a near-/mid-IR search for submillimetre galaxies over a region of 6230 deg2 of the southern sky. We used a cross-correlation of the...
  • Publication
    A New Chemo-evolutionary Population Synthesis Model for Early-Type Galaxies. I. Theoretical Basis
    We have developed a new stellar population synthesis model designed to study early-type galaxies. It provides optical and near-infrared colors, and line indices...
  • Publication
    A New Chemo-evolutionary Population Synthesis Model for Early-Type Galaxies. II. Observations and Results
    We present the results of applying a new chemo-evolutionary stellar population model, developed in a previous paper, to new high-quality observational data of...
  • Publication
    A new class of dark matter-free dwarf galaxies?: I. Clues from FCC 224, NGC 1052-DF2, and NGC 1052-DF4
    Context. The discovery of quiescent, dark matter (DM)-deficient ultra-diffuse galaxies (UDGs) with overluminous globular clusters (GCs) has challenged galaxy...
  • Publication
    A new discovery space opened by eROSITA. Ionised AGN outflows from X-ray selected samples
    Context. In the context of an evolutionary model, the outflow phase of an active galactic nucleus (AGN) occurs at the peak of its activity, once the central...
