The first generation of ELT instruments includes an optical-infrared high-resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion E…
Rapid Response Mode observations of GRB 160203A: Looking for fine-structure line variability at z=3.52
G. Pugliese, A. Saccardi, V. D Elia +26
Gamma-ray bursts are the most energetic known explosions. Despite fading rapidly, they allow to measure redshift and important properties of their host-galaxies. We report the phot…
The α-element enrichment of gas in distant galaxies
