    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...

    Low-redshift quasars in the SDSS Stripe 82 - II. Associated companion galaxies and signature of star formation
    We present optical spectroscopy of the close companions of 22 low-redshift (z < 0.5) quasars (QSO) selected from a larger sample of QSO in the SDSS Stripe82...

    Low-resolution spectroscopy and spectral energy distributions of selected sources towards σ Orionis
    Aims: We study in detail nine sources in the direction of the young σ Orionis cluster, which is considered to be a unique site for studying stellar and...

    Luminosity functions for galaxies and quasars in the Spitzer Wide-area Infrared Extragalactic Legacy Survey
    We construct rest-frame luminosity functions (LFs) at 3.6, 4.5, 5.8, 8 and 24 μm over the redshift range 0 z 2 for galaxies and 0 z 4 for optical quasi...

    Luminous Blue Variables in the local universe
    Preliminary results of a candidate luminous blue variable (LBV) search made in a region of M33 are presented. The objects were found with narrow band filter...

    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...

    Luminous Red Stars in Local Group Dwarf Elliptical Galaxies: an Intermediate-Age Population?
    In this Letter, we show that the optically bright stars above the tip of the first red giant branch (TRGB) in the color-magnitude diagrams (CMDs) of nearby...
