    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 ⊙)...
