Chemical abundance patterns at z=1-7: Carbon, Nitrogen, Neon, Sulphur, and Argon abundances from JWST spectroscopy

E. Cataldi, F. Belfiore, M. Curti +22

The relative abundances of chemical elements in the interstellar medium (ISM) trace the history of star formation and chemical enrichment in galaxies. We investigate the abundance…

Dual and lensed AGN at sub-arcsecond separations uncovered by ERIS

M. V. Zanchettin, F. Mannucci, Q. D'Amato +62

We present the first results of the ongoing INAF GTO program focused on the search of sub-arcsecond dual AGN, carried out with the near-infrared integral-field unit SPIFFIER of the…

Low-power jet-ISM coupling and disk-plane perturbations in the edge-on Seyfert galaxy NGC 4388

M. Ceci, G. Venturi, C. Marconcini +26

Active galactic nuclei (AGN) may regulate galaxy evolution through radiatively driven winds and collimated jets, but their relative impact and coupling to the interstellar medium (…

Unsupervised selection and characterisation of Little Red Dots in JWST surveys with manifold learning

Michele Ginolfi, Filippo Mannucci, Alessandro Marconi +9

Little Red Dots (LRDs) are compact, red sources discovered at high redshift by JWST whose physical nature and selection function remain debated. We investigate whether an unsupervi…

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…

Fast, dust-poor outflows in the local candidate dual AGN MCG-03-34-64 observed with VLT/ERIS

I. Lamperti, F. Mannucci, E. Bertola +28

We present VLT/ERIS IFU J-band observations of MCG-03-34-64, a nearby (z = 0.0167) Seyfert galaxy hosting a candidate dual AGN system with a separation of ~100 pc between the nucle…

MIRACLE III. JWST/MIRI expose the hidden role of the AGN outflow in NGC 1068

C. Marconcini, A. Marconi, M. Ceci +27

We present new JWST IFS observations of the active galaxy NGC 1068, combining Mid-IR and optical IFS data from MIRI and MUSE to characterize the multi-phase circumnuclear gas prope…

Cosmic Duets I. High-spatial resolution spectroscopy of dual and lensed AGN with MUSE-NFM

M. Scialpi, F. Mannucci, Q. D'Amato +34

We present the first-year results of the MUSE Large Program "Cosmic Duets", whose goal is to obtain adaptive-optics assisted MUSE observations with an angular resolution of 0.1"-0.…

Tracing nitrogen enrichment across cosmic time with JWST

E. Cataldi, F. Belfiore, M. Curti +22

We present a comprehensive analysis of the nitrogen-to-oxygen (N/O) abundance ratio in a sample of ~ 660 star-forming galaxies at redshift z ~ 1-6, with a median redshift of z = 3.…

Euclid: A machine-learning search for dual and lensed AGN at sub-arcsec separations

L. Ulivi, F. Mannucci, M. Scialpi +189

Cosmological models of hierarchical structure formation predict the existence of a widespread population of dual accreting supermassive black holes (SMBHs) on kpc-scale separations…

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…
