    SDSS-IV MaNGA: faint quenched galaxies - I. Sample selection and evidence for environmental quenching
    Using kinematic maps from the Sloan Digital Sky Survey (SDSS) Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, we reveal that the majority of...

    SDSS-IV MaNGA: Spatial Evolution of Star Formation Triggered by Galaxy Interactions
    Galaxy interaction is considered a key driver of galaxy evolution and star formation (SF) history. In this paper, we present an empirical picture of the radial...
  • Publication
    SDSS-IV MaNGA: stellar population gradients within barred galaxies
    Bars in galaxies are thought to stimulate both inflow of material and radial mixing along them. Observational evidence for this mixing has been inconclusive so...

    SDSS-IV MaNGA: the role of the environment in AGN triggering
    The large- and small-scale environments around optically-selected AGN host galaxies and a control sample of non-active galaxies in the MaNGA survey have been...

    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...
  • Publication
    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 for an extended VHE γ-ray emission from Mrk 421 and Mrk 501 with the MAGIC Telescope
    Context. Part of the very high energy γ-ray radiation coming from extragalactic sources is absorbed through the pair production process on the extragalactic...

    Search for Blue Compact Dwarf Galaxies During Quiescence
    Blue compact dwarf (BCD) galaxies are metal-poor systems going through a major starburst that cannot last for long. We have identified galaxies which may be...

    Search for Blue Compact Dwarf Galaxies During Quiescence. II. Metallicities of Gas and Stars, Ages, and Star Formation Rates
    We examine the metallicity and age of a large set of Sloan Digital Sky Survey/Data Release 6 galaxies that may be blue compact dwarf (BCD) galaxies during...
