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…

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…
