    The dust masses of powerful radio galaxies: clues to the triggering of their activity
    We use deep Herschel Space Observatory observations of a 90 per cent complete sample of 32 intermediate-redshift 2Jy radio galaxies (0.05 z 0.7) with strong...

    The FR II Broad-Line Seyfert 1 Galaxy: PKS J1037-2705
    In this article we demonstrate that PKS J1037-2705 has a weak accretion flow luminosity, well below the Seyfert 1/QSO dividing line, weak broad emission lines...

    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 June 2008 Flare of Markarian 421 from Optical to TeV Energies
    We present optical, X-ray, high-energy (lap30 GeV) and very high energy (gap100 GeV; VHE) observations of the high-frequency peaked blazar Mrk 421 taken between...

    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 MURALES survey. VI. Properties and origin of the extended line emission structures in radio galaxies
    This is the sixth paper presenting the results of the MUse RAdio Loud Emission line Snapshot survey. We observed 37 radio sources from the 3C sample with z < 0...

    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...
