Constraints on Dynamical Dark Energy Models from the Abundance of Massive Galaxies at High Redshifts
N. Menci, A. Grazian, M. Castellano +9
We compare the maximal abundance of massive systems predicted in different dynamical dark energy (DDE) models at high redshifts z = 4-7 with the measured abundance of the most mass…

The spectroscopic follow-up of the QUBRICS bright quasar survey
K. Boutsia, A. Grazian, G. Calderone +11
We present the results of the spectroscopic follow up of the QUBRICS survey. The selection method is based on a machine learning approach applied to photometric catalogs, covering…

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…
