Chemical enrichment in LINERs from MaNGA. II. Characterizing the shape of their radial metallicity gradients
Borja Pérez-Díaz, José M. Vílchez, Enrique Pérez Montero +3
Chemical abundance radial gradients provide key information on how the processes that affect chemical enrichment of the gas-phase interstellar medium (ISM) act at different galaxy…
Investigating ionising sources and the complex interstellar medium of GHZ2 at
M. Castellano, L. Napolitano, B. Moreschini +27
An accurate characterisation of the physical properties of galaxies at cosmic dawn is key to understanding the origin of the high abundance of UV-bright galaxies at z10. W…
Sulphur abundances in star-forming regions from optical emission lines: A new approach based on photoionization models consistent with the direct method
Enrique Pérez-Montero, Borja Pérez-Díaz, José M. Vílchez +5
The derivation of sulphur chemical abundances in the gas-phase of star-forming galaxies is explored in this work, using the emission lines produced in these regions in the optical…
Exploring the hardness of the ionizing radiation with the infrared softness diagram. II. Bimodal distributions in both the ionizing continuum slope and the excitation in active galactic nuclei
E. Pérez-Montero, J. A. Fernández-Ontiveros, B. Pérez-Díaz +2
After exploring the infrared softness diagram to characterize the hardness of the incident ionizing radiation in star-forming regions, we exploit the availability of high-excitatio…
