Structural, thermal and optical tolerance analysis of SHARP, a near infrared spectrograph for next generation telescope
H. Mahmoodzadeh, P. Saracco, I. DI Antonio +15
The design and verification of cryogenic near-infrared spectrographs require rigorous multidisciplinary analyses to ensure optical performance under realistic operational condition…
Probing IMF Variations in High-Redshift Early-Type Galaxies with SHARP
F. La Barbera, G. De Lucia, F. Ditrani +9
The stellar initial mass function (IMF), which describes the distribution of stellar masses at birth, is a fundamental ingredient in shaping galaxy evolution. Recent observations i…
SHARP -- A spectrograph proposal to fully exploit ELT capabilities and look beyond JWST
P. Saracco, P. Conconi, C. Arcidiacono +47
The Extremely Large Telescopes (ELTs), with their large apertures and cutting-edge Multi-Conjugate Adaptive Optics (MCAO) systems, promise to deliver data that is both sharper and…
Milky-Way-like stars in a galaxy core 8 billion years ago revealed by gravitational lensing
Quirino D'Amato, Filippo Mannucci, Alessandro Sonnenfeld +40
The assembly of stellar-dominated cores in elliptical galaxies is key to understanding how cosmic structures evolved. Gravitational lensing offers unique insights into the nature o…
Feeding the Dead: Neutral Gas Inflow in a Long-Quenched Ancient Massive Galaxy at Observed with JWST/NIRSpec
Davide Bevacqua, Danilo Marchesini, Paolo Saracco +16
We report the spectroscopic detection of neutral gas inflow into a massive () quiescent galaxy observed at with JWST. F…
SHARP: Beyond JWST -- Revealing the galaxy birth and growth with the resolution of the ELT
P. Saracco, P. Conconi, C. Arcidiacono +37
A deep understanding of the life-cycle of galaxies, particularly those of high mass, requires clarifying the mechanisms that regulate star formation (SF) and its abrupt shutdown (q…
