The accretion of quasars at the epoch of reionisation: catches the primeval monsters slowly feasting
B. Trefoloni, E. Nardini, S. Carniani +8
Quasars (QSOs) emit an enormous amount of light as a result of the accretion of gas onto supermassive black holes (SMBHs). Thanks to their luminosity, the most distant known QSOs a…
The near-infrared SED of blue quasars: what drives the evolution of the dusty torus?
Bartolomeo Trefoloni, Roberto Gilli, Elisabeta Lusso +5
A fundamental ingredient in the unified model of active galactic nuclei (AGN) is the obscuring torus, whose innermost, hottest region dominates the near infrared (NIR) emission. Ch…
Quasars as standard candles VI: spectroscopic validation of the cosmological sample
Bartolomeo Trefoloni, Elisabeta Lusso, Emanuele Nardini +5
A sample of quasars has been recently assembled to investigate the non-linear relation between their monochromatic luminosities at 2500Å, and 2 keV and to exploit quasars as a new…
Quasars as standard candles III. Validation of a new sample for cosmological studies
E. Lusso, G. Risaliti, E. Nardini +15
We present a new catalogue of ~2,400 optically selected quasars with spectroscopic redshifts and X-ray observations from either Chandra or XMM-Newton. The sample can be used to inv…
End to end simulators: A flexible and scalable Cloud-Based architecture. Application to High Resolution Spectrographs ESPRESSO and ELT-HIRES
M. Genoni, M. Landoni, G. Pariani +7
Simulations of frames from existing and upcoming high-resolution spectrographs, targeted for high accuracy radial velocity measurements, are computationally demanding (both in time…
The VLT/MUSE view of the central galaxy in Abell 2052. Ionized gas swept by the expanding radio source
B. Balmaverde, A. Capetti, A. Marconi +1
We report observations of the radio galaxy 3C317 (at z=0.0345) located at the center of the Abell cluster A2052, obtained with the VLT/MUSE integral field spectrograph. The Chandra…
