    Looking into the faintEst WIth MUSE (LEWIS): Exploring the nature of ultra-diffuse galaxies in the Hydra-I cluster: II. Stellar kinematics and dynamical masses
    Context. This paper focuses on a class of galaxies characterised by an extremely low surface brightness: ultra-diffuse galaxies (UDGs). We used new integral...

    Low deuterium abundance in the z_abs=3.514 absorber towards APM 08279+5255
    {A high-resolution, high signal-to-noise HIRES-Keck spectrum of APM 08279+5255 reveals a feature in the HI Lyalpha profile of the z_abs=3.514 absorber at the...

    Low optical polarization at the core of the optically thin jet of M87
    We study the optical linear and circular polarization in the optically thin regime of the core and jet of M87. Observations were acquired two days before the...

    Low-density star cluster formation: discovery of a young faint fuzzy on the outskirts of the low-mass spiral galaxy NGC 247
    The classical globular clusters found in all galaxy types have half-light radii of r h ~ 2-4 pc, which have been tied to formation in the dense cores of giant...

    Low-metallicity (sub-SMC) massive stars
    The double distance and metallicity frontier marked by the SMC has been finally broken with the aid of powerful multi-object spectrographs installed at 8-10m...

    Low-metallicity globular clusters in the low-mass isolated spiral galaxy NGC 2403
    The globular cluster (GC) systems of low-mass late-type galaxies, such as NGC 2403, have been poorly studied to date. As a low mass galaxy (M * = 7 × 10 9 M ⊙)...

    Low-power jet-interstellar medium interaction in NGC 7319 revealed by JWST/MIRI MRS
    We present JWST/MIRI MRS spectroscopy of NGC 7319, the largest galaxy in the Stephan's Quintet, observed as part of the Early Release Observations (ERO). NGC...
