A big step forward with SHARP: spatially resolved stellar population properties in passive galaxies at z > 1.5

A. Gargiulo, C. Mancini, F. R. Ditrani +6

Understanding when and how massive quiescent galaxies (log(M*/Msun) > 10.5) assembled their stellar mass and quenched remains a central challenge in galaxy evolution. Spatially res…

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…

A SHARP Look at Quenching and Bulge-Disk Growth in Massive Galaxies at Cosmic Noon

Chiara Mancini, Adriana Gargiulo, Alvio Renzini +11

The physical mechanisms that quench star formation in massive galaxies remain poorly understood. At cosmic noon (1<z<3), when star formation and AGN activity peak, galaxies rapidly…

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…

Contrasting evolutionary pathways of fast- and slow-rotating galaxies in the green valley

Shuang Zhou, Angela Iovino, Marcella Longhetti +2

We investigate the evolutionary pathways of green valley (GV) galaxies drawn from the SDSS-IV/MaNGA survey. The GV sample is divided into fast- and slow-rotating galaxies based on…

Decomposing the growth mechanisms of galaxies over the last 10 billion years

Luke J. M. Davies, Annagrazia Puglisi, Marcella Longhetti +10

Determining how galaxies accumulate stellar mass is paramount to understanding the Universe. Two primary mechanisms drive this process: star-formation (SF) & mergers. Our understan…
