A high space density of L* Active Galactic Nuclei at z~4 in the COSMOS field
K. Boutsia, A. Grazian, E. Giallongo +2
Identifying the source population of ionizing radiation, responsible for the reionization of the universe, is currently a hotly debated subject with conflicting results. Studies of…
CANDELSz7: a large spectroscopic survey of CANDELS galaxies in the reionization epoch
L. Pentericci, E. Vanzella, M. Castellano +15
We present the results of CANDELSz7, an ESO large program aimed at confirming spectroscopically a homogeneous sample of z~6 and z~7 star forming galaxies. The candidates were selec…
SHARK-NIR, the coronagraphic camera for LBT, moving toward construction
Jacopo Farinato, Francesca Bacciotti, Carlo Baffa +37
SHARK-NIR is one of the two coronagraphic instruments proposed for the Large Binocular Telescope. Together with SHARK-VIS (performing coronagraphic imaging in the visible domain),…
Spectroscopic investigation of a reionized galaxy overdensity at z=7
M. Castellano, L. Pentericci, E. Vanzella +17
We present deep spectroscopic follow-up observations of the Bremer Deep Field (BDF) where the two 7 bright Ly emitters (LAE) BDF521 and BDF3299 were previously discovered…
The contribution of faint AGNs to the ionizing background at z~4
A. Grazian, E. Giallongo, K. Boutsia +21
Finding the sources responsible for the hydrogen reionization is one of the most pressing issues in cosmology. Bright QSOs are known to ionize their surrounding neighborhood, but t…
