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...

PublicationConstraint on the time variation of the fine-structure constant with the SDSS-III/BOSS DR12 quasar sample
From the Sloan Digital Sky Survey (SDSS) Data Release 12, which covers the full Baryonic Oscillation Spectroscopic Survey (BOSS) footprint, we investigate the...

PublicationCross-correlation of SDSS DR7 Quasars and DR10 BOSS Galaxies: The Weak Luminosity Dependence of Quasar Clustering at z ~ 0.5
We present the measurement of the two-point cross-correlation function (CCF) of 8198 Sloan Digital Sky Survey Data Release 7 quasars and 349,608 Data Release 10...

PublicationDark Matter Mass Fraction in Lens Galaxies: New Estimates from Microlensing
We present a joint estimate of the stellar/dark matter mass fraction in lens galaxies and the average size of the accretion disk of lensed quasars based on...

PublicationDeciphering Quasar Millilensing How to Distinguish Between Dark and Luminous Lenses
Dwarf-galaxy sized dark matter halos may be detectable when a bright background source is gravitationally lensed on scales of milliarcseconds. Such effects can...
