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…

Cosmic Duets II. Growth and accretion in Gaia Multi-Peak dual AGN at Cosmic Noon

M. Scialpi, F. Mannucci, D. Izquierdo-Villalba +36

We present the first statistical characterization of the physical properties of Cosmic Duets: dual AGN in the redshift range 0.5 z 3.0 with projected separations of 1…

LoTSS of dual AGN: enhanced detectability and prospects for a systematic search

Q. D'Amato, F. Mannucci, E. De Rubeis +25

Context: Dual active galactic nuclei (DAGN) - systems of two accreting supermassive black holes at kpc-scale separations - trace galaxy mergers and are the progenitors of gravitati…

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 (…

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…

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…

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…

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…

Growing a nuclear star cluster from star formation and cluster mergers: The JWST NIRSpec view of NGC 4654

Katja Fahrion, Torsten Böker, Michele Perna +10

We present a detailed study of the centre of NGC4654, a Milky Way-like spiral galaxy in the Virgo cluster that has been reported to host a double stellar nucleus, thus promising a…

No evidence of AGN features in the nuclei of Arp 220 from JWST/NIRSpec IFS

Michele Perna, Santiago Arribas, Isabella Lamperti +12

Arp 220 is the nearest ULIRG; it shows evidence of 100 pc-scale molecular outflows likely connected with galaxy-scale outflows traced by ionised and neutral gas. The two highly obs…
