    The OTELO survey. I. Description, data reduction, and multi-wavelength catalogue
    Context. The evolution of galaxies through cosmic time is studied observationally by means of extragalactic surveys. The usefulness of these surveys is greatly...
  • Publication
    The OTELO survey. II. The faint-end of the Hα luminosity function at z ̃ 0.40
    Aims: We take advantage of the capability of the OTELO survey to obtain the Hα luminosity function (LF) at z ̃ 0.40. Because of the deepest coverage of OTELO...

    The OTELO survey. III. Demography, morphology, IR luminosity and environment of AGN hosts
    Aims: We take advantage of the capabilities of the OSIRIS Tunable Emission Line Object (OTELO) survey to select and study the AGN population in the field. In...
  • Publication
    The OTELO survey. Revealing a population of low-luminosity active star-forming galaxies at z ∼ 0.9
    Aims: We study a sample of Hβ emission line sources at z ∼ 0.9 to identify the star-forming galaxies sample and characterise them in terms of line luminosity...

    The OTELO Survey: The Star Formation Rate Evolution of Low-mass Galaxies
    We present the analysis of a sample of Hα, Hβ, and [O II] emission line galaxies from the OTELO survey, with masses typically below $\mathrm{log}({M}_{* }/{M}_{...

    The PAU Survey and Euclid: Improving broadband photometric redshifts with multi-task learning
    Current and future imaging surveys require photometric redshifts (photo-zs) to be estimated for millions of galaxies. Improving the photo-z quality is a major...

    The properties of cataclysmic variables in photometric Hα surveys
    We report on the properties of 71 known cataclysmic variables (CVs) in photometric Hα emission-line surveys. Our study is motivated by the fact that the Isaac...
  • Publication
    The properties of the T8.5p dwarf Ross 458C
    We present near-infrared photometry and spectroscopy, and warm-Spitzer IRAC photometry of the young very cool T dwarf Ross 458C, which we have typed as T8.5p...

    The QUEST RR Lyrae Survey. I. The First Catalog
    With the 1 m Schmidt telescope of the Llano del Hato Observatory and the QUEST CCD camera, 380 deg2 of the sky have been surveyed for RR Lyrae variables in a...
