Obscuration in high redshift jetted QSO
A. Caccianiga, L. Ighina, A. Moretti +6
Obscuration in high-redshift quasi-stellar objects (QSO) has a profound impact on our understanding of the evolution of supermassive black holes across the cosmic time. An accurate…
The first blazar observed at z>6
S. Belladitta, A. Moretti, A. Caccianiga +9
We present the discovery of PSO J030947.49+271757.31, the radio brightest (23.7 mJy at 1.4 GHz) active galactic nucleus (AGN) at z>6.0. It was selected by cross-matching the NRAO V…
The jet of the BL Lacertae object PKS 2201+044: MAD near-IR adaptive optics observations and comparison with optical, radio and X-ray data
E. Liuzzo, R. Falomo, A. Treves +14
Relativistic jets are a common feature of radio loud active galactic nuclei. Multifrequency observations are a unique tool to constrain their physics. We report on a detailed study…
MCAO near-IR photometry of the Globular Cluster NGC 6388: MAD observations in crowded fields
A. Moretti, G. Piotto, C. Arcidiacono +15
Deep photometry of crowded fields, such as Galactic Globular Clusters, is severely limited by the actual resolution of ground-based telescopes. On the other hand, the Hubble Space…
