CharlaDusting off the star formation history of AGN hosts with SHARDS
Recent works show that the restframe colours of X-ray selected AGN host galaxies at z~1 are no different from those of inactive galaxies once stellar mass...

PublicaciónExtended X-Ray Emission around FR II Radio Galaxies: Hot Spots, Lobes, and Galaxy Clusters
We present a systematic analysis of the extended X-ray emission discovered around 35 FR II radio galaxies from the revised Third Cambridge Catalog (3CR) Chandra...

CharlaFeII emission in active galactic nuclei: results from NIR Spectroscopy
FeII comprises up to one third of the line emission in AGNs. For that reason it is an important coolant that needs to be taken into accountto fully understand...

CharlaGamma rays from the Universe’s middle age: pushing Very High Energy Astrophysics boundaries with MAGIC
The search for detection of gamma-rays in the very-high-energy range (VHE, >100GeV) from distant AGNs by Imaging Atmospheric Cherenkov Telescopes (IACTs) gets...

CharlaGenuine spectral energy distribution of active galactic nuclei
Spectral energy distributions (SEDs) of the central few tens of parsec region of some of the nearest active galactic nuclei (AGN) are presented. Peering into...

PublicaciónGradients of excitation in the nuclei of starburst galaxies
The use of long-slit spectroscopy at high spectral and spatial resolution has made it possible to measure gradients of gaseous excitation and also velocity...

PublicaciónImage sharpening observations of active galactic nuclei
It is shown that recentering, selecting, and adding up sharp short-exposure images obtained with a photon-counting detector working in time-resolved mode can...

PublicaciónIndividual Estimates of the Virial Factor in 10 Quasars: Implications on the Kinematics of the Broad-line Region
Assuming a gravitational origin for the Fe iiiλλ2039-2113 redshift and using microlensing based estimates of the size of the region emitting this feature, we...
