    Lucky spectroscopy, an equivalent technique to lucky imaging. II. Spatially resolved intermediate-resolution blue-violet spectroscopy of 19 close massive binaries using the William Herschel Telescope
    Context. Many massive stars have nearby companions. These hamper a characterization of massive stars through spectroscopy. Aims: We continue to obtain spatially...

    Luminous giants populate the dense Cosmic Web. The radio luminosity-environmental density relation for radio galaxies in action
    Context. Giant radio galaxies (GRGs, giant RGs, or giants) are megaparsec-scale, jet-driven outflows from accretion disks of supermassive black holes, and...

    Lyman continuum leaker candidates at z ∼ 3-4 in the HDUV based on a spectroscopic sample of MUSE LAEs
    Context. In recent years, a number of Lyman continuum (LyC) leaker candidates have been found at intermediate redshifts, providing insight into how the Universe...

    Lyman-continuum leakage as dominant source of diffuse ionized gas in the Antennae galaxy
    The Antennae galaxy (NGC 4038/39) is the closest major interacting galaxy system and is therefore often studied as a merger prototype. We present the first...

    M 2-9: moving dust in a fast bipolar outflow.
    Using optical images and spectra of the bipolar nebula M 2-9 we show that, in addition to the well-known bright inner nebula, the object has fast, highly...

    M1-78: a nitrogen-rich Galactic compact H II region beyond the Perseus arm
    Context: There is considerable controversy surrounding the nature of M1-78, a compact nebula located beyond the Perseus arm. It was first classified as a...
