    SDSS superclusters: morphology and galaxy content
    Context. Understanding the formation, evolution and present-day properties of the cosmic web and objects forming it is an important task in cosmology. Aims: We...

    SDSS-V LVM: Detectability of Wolf-Rayet stars and their He II ionizing flux in low-metallicity environments: I. The weak-lined, early-type WN3 stars in the SMC
    The Small Magellanic Cloud (SMC) is the nearest low-metallicity dwarf galaxy. Its proximity and low reddening has enabled us to detect its Wolf-Rayet (WR) star...

    SDSS-V LVM: Resolving physical conditions in the Trifid Nebula
    Aims. The chemical abundance of the interstellar medium sets the initial conditions for star formation and provides a probe of chemical galaxy evolution models...

    SDSS-V LVM: Verifying what, and where, the "Galactic center lobe" is
    The so-called "Galactic center lobe" (GCL) is an extended (~1°) radio continuum feature situated above the Galactic plane, the nature and location of which have...

    Search and analysis of giant radio galaxies with associated nuclei (SAGAN). IV. Interplay with the Supercluster environment
    We investigated the prevalence of giant radio galaxies (GRGs), some of the largest structures powered by supermassive black holes, within supercluster...

    Search and analysis of giant radio galaxies with associated nuclei (SAGAN): V. Study of giant double-double radio galaxies from LoTSS DR2
    To test the hypothesis that megaparsec-scale giant radio galaxies (GRGs) experience multiple epochs of recurrent activity leading to their giant sizes and to...

    Search and characterization of T-type planetary mass candidates in the σ Orionis cluster
    Context. The proper characterization of the least massive population of the young σ Orionis star cluster is required to understand the form of the cluster mass...

    Search for flares and associated CMEs on late-type main-sequence stars in optical SDSS spectra
    Aims: This work aims to detect and classify stellar flares and potential stellar coronal mass ejection (CME) signatures in optical spectra provided by the Sloan...
