The gradual decline of Ly visibility in the CANDELS fields: evidence for the combined effects of galaxy evolution and reionization
L. Napolitano, L. Pentericci, A. Ferrara +35
We investigate the evolution of Ly visibility and the physical properties of Ly emitters (LAEs) across the five CANDELS fields using publicly available JWST/NIRSpec PRISM spe…
HII-CHI-mistry for active galactic nuclei: optical sulphur abundances without empirical ionisation correction factors
E. Pérez-Montero, O. L. Dors, I. A. Zinchenko +2
> The determination of sulphur abundances in active galactic nuclei (AGN) is uncertain because ionisation correction factors (ICFs) are commonly calibrated for HII regions. We exte…
From "The Cliff" to "Virgil": Mapping the Spectral Diversity of Little Red Dots with JWST/NIRSpec
Guillermo Barro, Pablo G. Perez-Gonzalez, Dale Kocevski +26
One of JWST's most unexpected discoveries is the emergence of "Little Red Dots'' (LRDs): compact sources at with blue rest-frame UV continua, red optical slopes, and…
The Early Maturity of High-Redshift Galaxies: Insights from sSFR, M/L and SFHs at z~7-14
P. Santini, M. Castellano, A. Calabrò +23
The James Webb Space Telescope (JWST) has revealed an unexpected excess of UV-bright galaxies at z>10, unaccounted for by extrapolations from pre-JWST observations and theoretical…
On the Contribution of Very Massive Stars to the Sulfur Abundance in Star-Forming Galaxies: the Role of PISN
S. Goswami, J. M. Vilchez, B. Perez-Diaz +3
Recent work presented increasing evidence of high, non-constant S/O abundance ratios observed in star-forming metal-poor galaxies, showing deviations from the constant canonical S/…
A MUSE/VLT spatially resolved study of the emission structure of Green Pea galaxies
A. Arroyo-Polonio, J. Iglesias-Páramo, C. Kehrig +6
Green Pea galaxies are remarkable for their intense star formation and serve as a window into the early universe. In our study, we used integral field spectroscopy to examine 24 of…
SOFIA observations of far-IR fine-structure lines in galaxies to measure metallicity
Luigi Spinoglio, Juan Antonio Fernandez-Ontiveros, Matthew A. Malkan +8
We present new and archival SOFIA FIFI-LS far-IR spectroscopic observations of 25 local galaxies of either the [OIII]52um and/or the [NIII]57um lines. Including other 31 galaxies f…
Chemical abundances in the nuclear region of nearby galaxies from the Palomar Survey
Borja Pérez-Díaz, Josefa Masegosa, Isabel Márquez +1
We estimate chemical abundances and ionization parameters in the nuclear region of a sample of 143 galaxies from the Palomar Spectroscopic Survey, composed by Star-Forming Galaxies…
