    Optical validation and characterization of Planck PSZ2 sources at the Canary Islands observatories. II. Second year of LP15 observations
    Context. The second legacy catalog of Planck Sunyaev-Zeldovich (SZ) sources, hereafter PSZ2, provides the largest galaxy cluster sample selected by means of the...
  • Publication
    Optical variability of the blazar 3C 371: From minute to year timescales
    Context. The BL Lac object 3C 371 was observed by the Transiting Exoplanet Survey Satellite (TESS) for approximately a year, between July 2019 and July 2020...
  • Publication
    Optical/NIR stellar absorption and emission-line indices from luminous infrared galaxies
    We analyse a set of optical-to-near-infrared long-slit nuclear spectra of 16 infrared-luminous spiral galaxies. All of the studied sources present H2 emission...

    Optical/X-ray/radio view of Abell 1213: A galaxy cluster with anomalous diffuse radio emission
    Context. Abell 1213, a low-richness galaxy system, is known to host an anomalous radio halo detected in data of the Very Large Array (VLA). It is an outlier...

    Optically Faint Massive Balmer Break Galaxies at z > 3 in the CANDELS/GOODS Fields
    We present a sample of 33 Balmer break galaxies (BBGs) selected as Hubble Space Telescope/F160W dropouts in the deepest CANDELS/GOODS fields (H ≳ 27.3 mag) but...

    Optimal Filter Systems for Photometric Redshift Estimation
    In the coming years, several cosmological surveys will rely on imaging data to estimate the redshift of galaxies, using traditional filter systems with 4-5...
  • Publication
    Optimizing spectral stacking for 21-cm observations of galaxies: accuracy assessment and symmetrized stacking
    We present an assessment of the accuracy of common operations performed in 21-cm spectral line stacking experiments. To this end, we generate mock...

    Orbit-based dynamical models of the Sculptor dSph galaxy
    We have developed spherically symmetric dynamical models of dwarf spheroidal (dSph) galaxies using Schwarzschild's orbit superposition method. This type of...
  • Publication
    Orbital decomposition of CALIFA spiral galaxies
    Schwarzschild orbit-based dynamical models are widely used to uncover the internal dynamics of early-type galaxies and globular clusters. Here we present for...
