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.…
M^3D: Mosaicking M33 with MUSE datacubes I. Unveiling the diversity of HII regions in M33 with MUSE
A. Feltre, F. Belfiore, G. Cresci +23
We present new VLT/MUSE observations of a 3 8 arcmin mosaic along the southern major axis of the Local Group galaxy M33. These data provide an unprecedented view of th…
MARTA: Temperature-temperature relationships and strong-line metallicity calibrations from multiple auroral-line detections at cosmic noon
E. Cataldi, F. Belfiore, M. Curti +22
We present the first results from MARTA (Measuring Abundances at high Redshift with the T Approach), a programme leveraging ultra-deep, medium-resolution JWST/NIRSpec spectrosc…
MIRACLE I.: Unveiling the Multi-Phase, Multi-Scale physical properties of the Active Galaxy NGC 424 with MIRI, MUSE, and ALMA
C. Marconcini, A. Feltre, I. Lamperti +26
We present the analysis of the multi-phase gas properties in the Seyfert II galaxy NGC 424, using spatially resolved spectroscopic data from JWST/MIRI, part of the Mid-InfraRed Act…
Gas-Phase metallicity for the Seyfert galaxy NGC 7130
Amirnezam Amiri, Johan H. Knapen, Sébastien Comerón +2
Metallicity measurements in galaxies can give valuable clues about galaxy evolution. One of the mechanisms postulated for metallicity redistribution in galaxies is gas flows induce…
Feedback and ionized gas outflows in four low-radio power AGN at z 0.15
L. Ulivi, G. Venturi, G. Cresci +19
An increasing number of observations and simulations suggests that low-power (<10 erg s) jets may be a significant channel of feedback produced by active galactic nuc…
HOMERUN a new approach to photoionization modelling. I -- reproducing observed emission lines with percent accuracy and obtaining accurate physical properties of the ionized gas
A. Marconi, A. Amiri, A. Feltre +26
We present HOMERUN (Highly Optimized Multi-cloud Emission-line Ratios Using photo-ionizatioN), a new approach to modelling emission lines from photoionized gas that can simultaneou…
The nature of the X-ray sources in dwarf galaxies in nearby clusters from the KIWICS
Şeyda Şen, Ersin Göğüş, Reynier F. Peletier +2
We present a deep search for and analysis of X-ray sources in a sample of dwarf galaxies (M < -15.5 mag) located within twelve galaxy clusters from the Kapteyn IAC WEAVE INT…
MOKA3D: An innovative approach to 3D gas kinematic modelling. I. Application to AGN ionized outflows
C. Marconcini, A. Marconi, G. Cresci +15
Studying the feedback process of Active Galactic Nuclei (AGN) requires characterising multiple kinematical components, such as rotating gas and stellar disks, outflows, inflows, an…
MUSE adaptive-optics spectroscopy confirms dual active galactic nuclei and strongly lensed systems at sub-arcsec separation
M. Scialpi, F. Mannucci, C. Marconcini +21
The novel Gaia Multi Peak (GMP) technique has proven to be able to successfully select dual and lensed AGN candidates at sub-arcsec separations. Both populations are important beca…
GMP-selected dual and lensed AGNs: selection function and classification based on near-IR colors and resolved spectra from VLT/ERIS, KECK/OSIRIS, and LBT/LUCI
F. Mannucci, M. Scialpi, A. Ciurlo +44
The Gaia-Multi-Peak (GMP) technique can be used to identify large numbers of dual or lensed AGN candidates at sub-arcsec separation, allowing us to study both multiple SMBHs in the…
The chemical enrichment in the early Universe as probed by JWST via direct metallicity measurements at z~8
M. Curti, F. D'Eugenio, S. Carniani +30
We analyse the chemical properties of three z~8 galaxies behind the galaxy cluster SMACS J0723.3-7327, observed as part of the Early Release Observations programme of the James Web…
The infrared-radio relation in the local universe
K. Tisanić, G. De Zotti, A. Amiri +3
The Square Kilometer Array (SKA) is expected to detect high-redshift galaxies with star formation rates (SFRs) up to two orders of magnitude lower than Herschel surveys and will th…
The diffuse ionized gas (DIG) in star-forming galaxies: the influence of aperture effects on local HII regions
F. Mannucci, F. Belfiore, M. Curti +7
The Diffuse Ionized Gas (DIG) contributes to the nebular emission of galaxies, resulting in emission line flux ratios that can be significantly different from those produced by HII…
Connecting X-ray nuclear winds with galaxy-scale ionised outflows in two lensed quasars
G. Tozzi, G. Cresci, A. Marasco +15
Outflows driven by active galactic nuclei (AGN) are expected to have a significant impact on the host galaxy evolution, but it is still debated how they are accelerated and propaga…
