PublicaciónThe curious activity in the nucleus of NGC 4151: jet interaction causing variability?
A key characteristic of many active galactic nuclei (AGNs) is their variability, but its origin is poorly understood, especially in the radio domain. Williams...

PublicaciónThe dual nature of blazar fast variability: Space and ground observations of S5 0716+714
Blazar S5 0716+714 is well-known for its short-term variability, down to intraday time-scales. We here present the 2-min cadence optical light curve obtained by...

PublicaciónThe 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...

PublicaciónThe 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...

PublicaciónThe 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...

CharlaThe 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...

PublicaciónThe 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...

PublicaciónThe 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...
