    The OTELO survey. Faint end of the luminosity function of [O II]3727 emitters at ⟨z⟩ = 1.43
    Aims: In this paper, we aim to study the main properties and luminosity function (LF) of the [O II]3727 emitters detected in the OTELO survey in order to...

    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...

    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 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 PAU Survey: Galaxy stellar population properties estimates with narrowband data
    A newfound interest has been seen in narrowband galaxy surveys as a promising method for achieving the necessary accuracy on the photometric redshift estimate...

    The Penn State - Toruń Centre for Astronomy Planet Search stars. II. Lithium abundance analysis of the red giant clump sample
    Context. Standard stellar evolution theory does not predict existence of Li-rich giant stars. Several mechanisms for Li-enrichment have been proposed to operate...

    The Penn State - Toruń Centre for Astronomy Planet Search stars. IV. Dwarfs and the complete sample
    Context. Our knowledge of the intrinsic parameters of exoplanets is as precise as our determinations of their stellar hosts parameters. In the case of radial...

    The polar orbit of the warm Neptune GJ 436b seen with VLT/ESPRESSO
    GJ 436b might be the prototype of warm Neptunes that have undergone late migration induced by an outer companion. Precise determination of the orbital...
