The Frontier Fields survey is a pioneering observational program aimed at collecting photometric data, both from space (Hubble Space Telescope and Spitzer Space Telescope) and from ground-based facilities (VLT Hawk-I), for six deep fields pointing at clusters of...

The process that quenched star formation in galaxies at intermediate and high redshift is still the subject of considerable debate. One way to investigate this puzzling issue is to study the number density of quiescent galaxies at z ≃ 2, and its dependence on mass....

With this paper we aim at constraining the assembly history of high-redshift galaxies and the reliability of UV-based estimates of their physical parameters from an accurate analysis of a unique sample of z∼3 Lyman break galaxies (LBGs). We analyse 14 LBGs at...

We present the results of a study investigating the rest-frame ultra-violet (UV) spectral slopes of redshift z ≈ 5 Lyman-break galaxies (LBGs). By combining deep Hubble Space Telescope imaging of the CANDELS and HUDF fields with ground-based imaging from the UKIDSS...

We present the results of a new search for bright star-forming galaxies at z ≃ 7 within the UltraVISTA DR2 and UKIDSS UDS DR10 data, which together provide 1.65 deg2 of near-infrared imaging with overlapping optical and Spitzer data. Using a full photometric redshift...
