    A possible shutting-down event of mass accretion in an active galactic nucleus at z ∼ 1.8
    We present the discovery of a large gradual apparent fading event in optical and near-infrared wavelengths in a quasar at $z=1.767$ by a factor of ${\sim}20\!-\...

    A possible signature of the influence of tidal perturbations in dwarf galaxy scaling relations
    Dwarf galaxies are excellent cosmological probes, because their shallow potential wells make them very sensitive to the key processes that drive galaxy...

    A Possible Surviving Companion of the SN Ia in the Galactic SNR G272.2-3.2
    We use the Gaia EDR3 to explore the Galactic supernova remnant (SNR) G272.2-3.2, produced by the explosion of a Type Ia supernova (SN Ia) about 7500 yr ago, to...

    A Possible Third Component in the L Dwarf Binary System DENIS-P J020529.0-115925 Discovered with the Hubble Space Telescope
    We present results showing that the multiple system DENIS-P J020529.0-115925 is likely to be a triple system of very low mass stars and brown dwarfs. The...

    A post-merger enhancement only in star-forming Type 2 Seyfert galaxies: the deep learning view
    Supermassive black holes require a reservoir of cold gas at the centre of their host galaxy in order to accrete and shine as active galactic nuclei (AGN). Major...

    A Precessing Collimated Outflow in the Quadrupolar Planetary Nebula NGC 6881
    We present high-quality (subarcsecond) optical narrowband CCD images of the planetary nebula NGC 6881, which reveal a highly collimated bipolar structure. A...
