A Dusty Quenching-candidate AGN host at z=5.7: massive quiescent galaxies may quench already during the dust-obscured phase

Francesco D'Eugenio, Matilde Brazzini, Roberto Maiolino +12

We present a spectro-photometric analysis of RUBIES-EGS-9809, a broad-line AGN host at z=5.7 with a Balmer break and a dominant point source. The source is dust reddened (3 m…

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…

A novel data-driven approach to extract stellar population properties from galaxy spectra using absorption indices

Zahra Sharbaf, Ignacio Ferreras, Anna R. Gallazzi +3

In an era of highly complex machine learning methods that often are informative but not straightforward to interpret, Principal Component Analysis (PCA) offers a simple, easily int…

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…
