    An extreme blue nugget, UV-bright starburst at z = 3.613 with 90 per cent of Lyman continuum photon escape
    We present the discovery and analysis of J1316+2614 at z = 3.6130, a UV-bright star-forming galaxy (M UV ≃ -24.7) with large escape of Lyman continuum (LyC)...

    An Extreme Protocluster of Luminous Dusty Starbursts in the Early Universe
    We report the identification of an extreme protocluster of galaxies in the early universe whose core (nicknamed Distant Red Core, DRC, because of its very red...

    An HST/WFPC2 survey of bright young clusters in M 31. IV. Age and mass estimates
    Aims: We present the main results of an imaging survey of possible young massive clusters (YMC) in M 31 performed with the Wide Field and Planetary Camera 2...

    An HST/WFPC2 survey of bright young clusters in M31. I. VdB0, a massive star cluster seen at t ≃ 25 Myr
    Aims: We introduce our imaging survey of possible young massive globular clusters in M31 performed with the Wide Field and Planetary Camera 2 (WFPC2) on the...

    An hydrodynamical model of the barred galaxy NGC 5850
    We present the results of hydrodynamical model calculations of the barred galaxy NGC 5850 and compare to HI observations. The models assume a mass distribution...

    An Hα Nuclear Spiral Structure in the E0 Active Galaxy Arp 102B
    We report the discovery of a two-armed mini-spiral structure within the inner kiloparsec of the E0 LINER/Seyfert 1 galaxy Arp 102B. The arms are observed in Hα...

    An image of the dust sublimation region in the nucleus of NGC 1068
    We present near-infrared interferometric data on the Seyfert 2 galaxy NGC 1068, obtained with the GRAVITY instrument on the European Southern Observatory Very...

    An Imaging Survey of Early-Type Barred Galaxies
    This paper presents the results of a high-resolution imaging survey, using both ground-based and Hubble Space Telescope images, of a complete sample of nearby...

    An Imperfectly Passive Nature: Bright Submillimeter Emission from Dust-obscured Star Formation in the z = 3.717 “Passive” System, ZF 20115
    The identification of high-redshift, massive galaxies with old stellar populations may pose challenges to some models of galaxy formation. However, to securely...
