    The uncertain interstellar medium of high-redshift quiescent galaxies: Impact of methodology
    How much gas and dust is contained in high-redshift quiescent galaxies (QGs) is currently an open question with relatively few and contradictory answers, as...

    The universal variability of the stellar initial mass function probed by the TIMER survey
    The debate about the universality of the stellar initial mass function (IMF) revolves around two competing lines of evidence. While measurements in the Milky...

    The Unrelaxed Dynamical Structure of the Galaxy Cluster Abell 85
    For the first time, we explore the dynamics of the central region of a galaxy cluster within r 500 ∼ 600 h‑1 kpc from its center by combining optical and X-ray...

    The unusual multi-wavelength SED of two optical dropout galaxies
    We have used deep optical, near-IR, and IR observations from VLT, Spitzer, Herschel, and LABOCA in strong lensing clusters to study distant galaxies. In...

    The Unusual Vertical Mass Distribution of NGC 4013 Seen through the Spitzer Survey of Stellar Structure in Galaxies (S4G)
    NGC 4013 is a nearby Sb edge-on galaxy known for its "prodigious" H I warp and its "giant" tidal stream. Previous work on this unusual object shows that it...

    The Updated BaSTI Stellar Evolution Models and Isochrones. I. Solar-scaled Calculations
    We present an updated release of the BaSTI (a Bag of Stellar Tracks and Isochrones) stellar model and isochrone library for a solar-scaled heavy element...

    The Uv Spectral Window: New Means To Constrain The Stellar Populations Of Early-Type Galaxies
    We discuss the possibilities of exploiting the UV spectral using the J-PAS survey to disentangle young contributions from apparently old galaxies. We show that...

    The UV-brightest Lyman continuum emitting star-forming galaxy
    We report the discovery of J0121+0025, an extremely luminous and young star-forming galaxy (M UV = -24.11, log[$L_{\rm Ly \alpha } / \rm erg~s^{-1}] = 43.8$) at...

    The V-band luminosity function of galaxies in A2151
    We present a wide field V-band imaging survey of approximately 1 deg2 (~7.2~h-275 Mpc2) in the direction of the nearby cluster of galaxies Abell 2151 (the...
