There is no single density: star-forming regions and galaxies hold more dense ionized gas than long assumed
J. Eduardo Méndez-Delgado, Christophe Morisset, William J. Henney +29
Ionized gas fills star-forming regions and galaxies, and nearly everything we know about its temperature, pressure, mass, and composition is inferred from its emission lines [1-3].…
Self-Consistent Direct Method for Chemical Abundances in High-z Galaxies with JWST
Karla Z. Arellano-Córdova, J. Eduardo Méndez-Delgado, Sophia R. Flury +10
The unprecedented rest-frame UV and optical coverage provided by JWST enables simultaneous constraints on the electron density (n) and temperature (T) of ionize…
The DESIRED temperature-metallicity relations in star-forming regions: probing the Galactic radial and azimuthal metallicity distributions
I. Rafael MartÃnez-Hernández, J. Eduardo Méndez-Delgado, César Esteban +17
We analyse a sample of 225 star-forming regions from the DESIRED-E project, each with simultaneous determinations of the electron temperature from ionized nitrogen and oxygen, $T_{…
On the chlorine abundance in H II regions
Maialen Orte-GarcÃa, César Esteban, José Eduardo Méndez-Delgado +1
Chlorine (Cl) is a chemical element of the group of the halogens and is between the 17th and the 20th most abundant elements in the Solar System. It is thought to be produced from…
