HYPERION: broad-band X-ray-to-near-infrared emission of Quasars in the first billion years of the Universe
I. Saccheo, A. Bongiorno, E. Piconcelli +41
We aim at characterizing the X-ray-to-optical/near-infrared broad-band emission of luminous QSOs in the first Gyr of cosmic evolution to understand whether they exhibit differences…
What are the Pillars of Reionization? Revising the AGN Luminosity Function at z~5
Andrea Grazian, Emanuele Giallongo, Konstantina Boutsia +22
In the past, high-z AGNs were given a minor role as possible drivers of reionization, despite initial evidences in favor of their large space densities at low luminosities by Chand…
Euclid. I. Overview of the Euclid mission
Euclid Collaboration, Y. Mellier, Abdurro'uf +1134
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…
HYPERION. Coevolution of supermassive black holes and galaxies at and the build-up of massive galaxies
R. Tripodi, C. Feruglio, F. Fiore +22
We used low- to high-frequency ALMA observations to investigate the cold gas and dust in ten QSOs at . Our analysis of the CO(6-5) and CO(7-6) emission lines in the sel…
Boost recall in QSO selection from highly imbalanced photometric datasets
Giorgio Calderone, Francesco Guarneri, Matteo Porru +9
Context. The identification of bright QSOs is of great importance to probe the intergalactic medium and address open questions in cosmology. Several approaches have been adopted to…
On the AGN nature of two UV bright sources at z_spec~5.5 in the CANDELS fields: an update of the AGN space density at M1450~-22.5
A. Grazian, E. Giallongo, F. Fiore +8
It is a widespread opinion that hydrogen reionization is mainly driven by primeval star-forming galaxies, with a minor role of high-z active galactic nuclei. Recent observations, h…
