    The host galaxy of the γ-ray-emitting narrow-line Seyfert 1 galaxy PKS 1502+036
    The detection of γ-ray emission from narrow-line Seyfert 1 galaxies (NLSy1) has challenged the idea that large black hole (BH) masses (≥108 M⊙) are needed to...

    The jet feedback mechanism: from supernovae to clusters of galaxies
    I will describe the roles of jets in several quite different astrophysical systems. These include exploding core collapse supernovae, expelling common envelopes...

    The MURALES survey. IV. Searching for nuclear outflows in 3C radio galaxies at z < 0.3 with MUSE observations
    We analyze VLT/MUSE observations of 37 radio galaxies from the Third Cambridge catalogue (3C) with redshift < 0.3 searching for nuclear outflows of ionized gas...

    The Nature and Evolution of Classical Double Radio Sources from Complete Samples
    We present a study of the trends in luminosity, linear size, spectral index, and redshift of classical double radio sources, from three complete samples...

    The optical behaviour of BL Lacertae at its maximum brightness levels: a blend of geometry and energetics
    In 2021 BL Lacertae underwent an extraordinary activity phase, which was intensively followed by the Whole Earth Blazar Telescope (WEBT) Collaboration. We...

    The redshift and broad-band spectral energy distribution of NRAO 150
    Context. NRAO 150 is one of the brightest radio and mm AGN sources in the northern sky, and is an interesting source to study extreme relativistic jet phenomena...

    The relation between optical and γ-ray emission in BL Lac sources
    The relativistic jets produced by some Active Galactic Nuclei (AGNs) are among the most efficient persistent sources of non-thermal radiation and represent an...
