    Large-scale environments of z < 0.4 active galaxies
    Context. Properties of galaxies depend on their large-scale environment. As the influence of active galactic nuclei (AGN) in galaxy evolution is becoming more...

    Large-scale solar motions as determined by Doppler shift measurements using a linear photodiode array
    Doppler shifts of the solar Fe line 630.15 nm relative to the terrestrial O2 line 630.2 nm were determined at many positions on the solar disk to investigate...

    Large-scale stellar age-velocity spiral pattern in NGC 4030
    The processes driving the formation and evolution of late-type galaxies continue to be a debated subject in extragalactic astronomy. Investigating stellar...

    Larger λ<SUB>R</SUB> in the disc of isolated active spiral galaxies than in their non-active twins
    We present a comparison of the spin parameter λ R, measured in a region dominated by the galaxy disc, between 20 pairs of nearby (0.005 < z < 0.03) seemingly...

    Learning about stars from their colors
    Aims: We pose the question of how much information on the atmospheric parameters of late-type stars can be retrieved purely from color information using...

    Learning to do multiframe wavefront sensing unsupervised: Applications to blind deconvolution
    Context. Observations from ground-based telescopes are severely perturbed by the presence of the Earth's atmosphere. The use of adaptive optics techniques has...

    LeMMINGs. V. Nuclear activity and bulge properties: A detailed multi-component decomposition of e-MERLIN Palomar galaxies with HST
    We used high-resolution HST imaging and e-MERLIN 1.5-GHz observations of galaxy cores from the LeMMINGs survey to investigate the relation between optical...

    Lens parameters for Gaia18cbf - a long gravitational microlensing event in the Galactic plane
    Context. The timescale of a microlensing event scales as a square root of a lens mass. Therefore, long-lasting events are important candidates for massive...

    Li abundances in F stars: planets, rotation, and Galactic evolution
    Aims: We aim, on the one hand, to study the possible differences of Li abundances between planet hosts and stars without detected planets at effective...
