Euclid preparation. Spectroscopy of active galactic nuclei with NISP
Euclid Collaboration, E. Lusso, S. Fotopoulou +246
The statistical distribution and evolution of key properties (e.g. accretion rate, mass, or spin) of active galactic nuclei (AGN), remain an open debate in astrophysics. The ESA Eu…
ACOSMOS: the infrared luminosity function and dust-obscured star formation rate density at
A. Traina, C. Gruppioni, I. Delvecchio +16
Aims: We leverage the largest available Atacama Large Millimetre/submillimetre Array (ALMA) survey from the archive (ACOSMOS) to study to study infrared luminosity function and…
CLASSY VIII: Exploring the Source of Ionization with UV ISM diagnostics in local High- Analogs
Matilde Mingozzi, Bethan L. James, Danielle A. Berg +27
In the current JWST era, rest-frame UV spectra play a crucial role in enhancing our understanding of the interstellar medium (ISM) and stellar properties of the first galaxies in t…
Near-infrared emission line diagnostics for AGN from the local Universe to redshift 3
Antonello Calabrò, Laura Pentericci, Anna Feltre +35
Optical rest-frame spectroscopic diagnostics are usually employed to distinguish between star formation and AGN-powered emission. However, this method is biased against dusty sourc…
JWST/NIRSpec Measurements of Extremely Low Metallicities in High Equivalent Width Lyman- Emitters
Michael V. Maseda, Zach Lewis, Jorryt Matthee +19
Deep VLT/MUSE optical integral field spectroscopy has recently revealed an abundant population of ultra-faint galaxies (; 0.01 ) at 2.96.7 due…
Chemical abundances in Seyfert galaxies X. Sulphur abundance estimates
O. L. Dors, M. Valerdi, R. A. Riffel +12
For the first time, the sulphur abundance relative to hydrogen (S/H) in the Narrow Line Regions of a sample of Seyfert 2 nuclei (Sy 2s) has been derived via direct estimation of th…
Delving deep: a population of extremely dusty dwarfs observed by JWST
L. Bisigello, G. Gandolfi, A. Grazian +21
We take advantage of the NIRCam photometric observations available as part of the Cosmic Evolution Early Release Science survey (CEERS) to identify and analyse very red sources in…
Optical and mid-infrared line emission in nearby Seyfert galaxies
A. Feltre, C. Gruppioni, L. Marchetti +24
Line ratio diagnostics provide valuable clues on the source of ionizing radiation in galaxies with intense black hole accretion and starbursting events, such as local Seyfert or ga…
