    The central molecular gas structure in LINERs with low luminosity AGN: evidence for gradual disappearance of the torus.
    We present observations of the molecular gas in the nuclear environment of three prototypical low luminosity AGN (LLAGN), based on VLT/SINFONI AO-assisted...

    The changing-look optical wind of the flaring X-ray transient Swift J1858.6-0814
    The large amount of mass and angular momentum carried by disc winds makes them key processes to understand accretion onto compact objects, such as black holes...

    The chemistry of Planetary Nebulae (PNe) and HII regions in the Local Group
    Chemical abundances have been measured of PNe and HII regions in Sex A and Sex B, two galaxies located on the outskirts of the Local Group. These PNe are the...

    The dark side of the fluffiest galaxies
    Ultra diffuse galaxies (UDGs) have the sizes of giants but the luminosities of dwarfs. A key to understanding their origins comes from their total masses, but...
