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…

One cloud is not enough: extreme conditions bias chemical abundances in high-redshift galaxies

Bianca Moreschini, Francesco Belfiore, Alessandro Marconi +18

Since its launch, JWST has opened an unprecedented opportunity to characterise the ionised ISM of high-redshift galaxies using well-established rest-frame UV/optical diagnostics fr…

The JWST/NIRSpec view of the nuclear region in the prototypical merging galaxy NGC 6240

Matteo Ceci, Giovanni Cresci, Santiago Arribas +9

Merger events are thought to be an important phase in the assembly of massive galaxies. At the same time, Active Galactic Nuclei (AGN) play a fundamental role in the evolution of t…

Classifying spectra of emission-line regions with neural networks -- An application to integral field spectroscopic data of M33

Caterina Bracci, Francesco Belfiore, Michele Ginolfi +13

Emission-line regions are key to understanding the properties of galaxies, as they trace the exchange of matter and energy between stars and the interstellar medium (ISM). In nearb…

JWST/NIRSpec insights into the circumnuclear region of Arp 220: A detailed kinematic study

L. Ulivi, M. Perna, I. Lamperti +13

The study of starburst and active galactic nuclei (AGN) feedback is crucial for understanding the regulation of star formation and the evolution of galaxies across cosmic time. Arp…
