PublicationCoevolution of supermassive black holes and their host galaxies
Accretion onto a supermassive black hole (BH) is the most viable explanation for the huge emitted luminosity in active galaxies. Nowadays a wealth of...

PublicationCompact radio-loud Broad Absorption Line Quasars .
For a long time, radio-loud Broad Absorption Line Quasars (BAL QSOs) were thought to be extremely rare objects. The absorbing troughs seen in their optical...

PublicationComplex AGN feedback in the Teacup galaxy. A powerful ionised galactic outflow, jet-ISM interaction, and evidence for AGN-triggered star formation in a giant bubble
Context. The z ∼ 0.1 type-2 QSO J1430+1339, known as the " Teacup", is a complex galaxy showing a loop of ionised gas ∼10 kpc in diameter, co-spatial radio...

PublicationConstraining the Epoch of Reionization from the Observed Properties of the High-z Universe
We combine observational data on a dozen independent cosmic properties at high-z with the information on reionization drawn from the spectra of distant luminous...

PublicationConstraining the nature of high frequency peakers. II. Polarization properties
Aims:The “bright” High Frequency Peakers (HFPs) sample is a mixture of blazars and intrinsically small and young radio sources. We investigate the polarimetric...
