    The OTELO survey: New evidence of downsizing from the specific star formation rates, stellar mass functions, and star formation histories of a sample of low-mass galaxies at 0.38 < z < 1.43
    Aims. We present an analysis of the emitters (Hα, Hβ, and [O II]) from the OTELO survey, in order to characterize the star formation properties of low-mass...

    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 Pristine survey: XXIII. Data Release 1 and an all-sky metallicity catalogue based on Gaia DR3 BP/RP spectro-photometry
    We used the spectro-photometric information of ∼219 million stars from Gaia's Data Release 3 (DR3) to calculate synthetic, narrowband, metallicity-sensitive...

    The Pristine survey: XXIV. The Galactic underdogs: Dynamic tales of a Milky Way metal-poor population
    Context. Metal-poor stars hold key information on the early Milky Way. Through the identification and characterisation of substructures, one can understand...

    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...

    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...

    The Radio Spectral Energy Distribution and Star-formation Rate Calibration in Galaxies
    We study the spectral energy distribution (SED) of the radio continuum (RC) emission from the Key Insight in Nearby Galaxies Emitting in Radio (KINGFISHER)...
