Il Very Large Telescope (VLT) dell’Osservatorio del Paranal è la struttura di punta dell’ESO e continua a rappresentare l’avanguardia dell’astronomia da terra, fornendo scienza trasformativa in una vasta gamma di settori. Grazie alla sua suite di potenti strumenti di seconda generazione — tra cui MUSE, KMOS, X-Shooter, SPHERE e GRAVITY — il VLT ha permesso importanti progressi nella nostra...
"MORFEO, one of the main ground-based astronomical projects with INAF leadership, will provide multi-conjugate adaptive optics corrections to the ESO Extremely Large Telescope instruments MICADO and HARMONI, allowing diffraction limited PSF over a large field of view. This will have a tremendous scientific impact in a large variety of fields, from planetary systems to resolved stellar...
HRMOS High resolution multi-object spectrograph è uno strumento che offrirà un insieme di
caratteristiche uniche, combinando una risoluzione spettrale molto alta (R=80,000), capacità multi-
oggetto (50-70), un’ ottima precisione in velocità radiale (10 m/s), e un'ampia copertura spettrale
fino a lunghezze d'onda blu (375 nm). Tali caratteristiche lo rendono complementare rispetto ad
altri...
"While significant progress has been made in compensating for atmospheric turbulence through adaptive optics systems at large ground-based telescopes, several key limitations still need to be addressed. Recent advancements and new concepts in Laser Guide Star wavefront sensing will significantly reduce the sky coverage problem, however, fully exploiting the potential of 8-10 meter class...
"Recent JWST observations have revolutionised our ability to characterise the gas-phase metallicities and mass-metallicity relation (MZR) of low-mass galaxies (log(M★/M⊙) < 10) at z > 2. These results suggest that feedback-driven gas outflows play a crucial role in regulating star formation and ejecting metals from shallow potential wells at early cosmic epochs. This picture aligns with...
"SAXO+ is a second-stage adaptive optics (AO) upgrade for the SPHERE instrument at the Very Large Telescope in Chile. The project aims to significantly enhance SPHERE’s performance by improving raw contrast at short angular separations, enabling access to a broader sample of young, redder, and fainter planetary systems. It will also increase sensitivity in the inner separation range, where...
