Euclid Quick Data Release (Q1): The impact of AGN emission on SED-derived physical properties
Euclid Collaboration, B. Laloux, A. Bongiorno +309
The Euclid Quick Data Release (Q1) is a powerful dataset to study active galactic nuclei (AGN) and their host galaxies. Deriving their physical properties through multi-component s…
Dust in the very metal-poor galaxy Sextans A with JWST. I: Characterizing the evolved stellar population of Sextans A based on JWST observations and stellar evolution models
C. Gavetti, F. Dell'Agli, E. Tarantino +22
The nearby star-forming dwarf galaxy Sextans A offers a unique window into galaxy evolution in the early Universe, owing to its extremely low metallicity (about 1-7% Zsun). Recent…
The first near-infrared high-resolution échelle spectroscopy of the outflow in NGC 4151. A study of the clouds covering the Eye of Sauron
Francesco Gabriele Saturni, Riccardo Middei, Hermine Landt +4
We present the first high-resolution near-infrared spectroscopy of the nucleus of the nearby, well-known Seyfert galaxy NGC 4151 (the "Eye of Sauron"). Past studies of this source…
BASS LV. Connecting X-ray variability with AGN physical properties and a new path to Cosmological distances
Matilde Signorini, Federica Ricci, Alessia Tortosa +18
X-ray variability is a well-established characteristic of active galactic nuclei (AGN), known to correlate inversely with both the supermassive black hole mass and luminosity, alth…
The applicability of the JAGB method for measuring the distance of galaxies subject to different metal enrichment rates
Claudio Gavetti, Paolo Ventura, Flavia Dell'Agli +4
The JAGB method has been proposed in recent years as a possible distance indicator for galaxies in the Local Group and beyond. However, the nature of the stars populating the J reg…
A deep X-ray look to the most obscured quasar at z~3.6 and its environment
I. Villani, L. Zappacosta, E. Piconcelli +17
The most luminous and obscured quasars (QSOs) detected in infrared all-sky surveys could represent a key co-evolutionary phase from nuclear to circum-galactic (CG) scales in the fo…
