SIPGI: an interactive pipeline for spectroscopic data reduction
Susanna Bisogni, Adriana Gargiulo, Marco Fumana +5
SIPGI is a spectroscopic pipeline for the data reduction of optical/near-infrared data acquired by slit-based spectrographs. SIPGI is a complete spectroscopic data reduction enviro…
The WISSH quasars project XI. The mean Spectral Energy Distribution and Bolometric Corrections of the most luminous quasars
Ivano Saccheo, Angela Bongiorno, Enrico Piconcelli +18
Hyper-luminous Quasi-Stellar Objects (QSOs) represent the ideal laboratory to investigate Active Galactic Nuclei (AGN) feedback mechanism since their formidable energy release caus…
A powerful (and likely young) radio-loud quasar at z=5.3
S. Belladitta, A. Moretti, A. Caccianiga +5
We present the discovery of PSO J191.0569686.43172 (hereafter PSO J19186), a new powerful radio-loud quasar (QSO) in the early Universe (z = 5.32). We discovered it by cross-…
SIPGI: an interactive pipeline for spectroscopic data reduction
A. Gargiulo, M. Fumana, S. Bisogni +5
We present SIPGI, a spectroscopic pipeline to reduce optical/near-infrared data from slit-based spectrographs. SIPGI is a complete spectroscopic data reduction environment which re…
Quasars as high-redshift standard candles
A. Sacchi, G. Risaliti, M. Signorini +10
The non-linear relation between the X-ray and ultraviolet (UV) luminosity in quasars has been used to derive quasar distances and to build a Hubble diagram at redshifts up to $z\si…
An X-ray fading, UV brightening QSO at
Fabio Vito, Marco Mignoli, Roberto Gilli +13
Explaining the existence of SMBHs at is a persistent challenge to modern astrophysics. Multi-wavelength observations of QSOs revea…
The WISSH quasars project X. Discovery of a multi-component and highly-variable UV ultra-fast outflow in a z=3.6 quasar
G. Vietri, T. Misawa, E. Piconcelli +16
We report on the variability of a multi-component broad absorption line (BAL) system observed in the hyper-luminous quasar J1538+0855 at z=3.6. Observations from SDSS, VLT, LBT and…
The Smallest Scale of Hierarchy Survey (SSH). II. Extended star formation and bar-like features in the dwarf galaxy NGC 3741: recent merger or ongoing gas accretion?
F. Annibali, C. Bacchini, G. Iorio +12
Using Large Binocular Telescope deep imaging data from the Smallest Scale of Hierarchy Survey (SSH) and archival Hubble Space Telescope data, we reveal the presence of two elongate…
