Investigating the electron temperature of [Ar IV] in planetary nebulae using the DESIRED database

J. García-Rojas, E. Reyes-Rodríguez, J. E. Méndez-Delgado +9

(Abridged) We investigate the behaviour of the electron temperature derived from [Ar IV] lines, Te([Ar IV]), in a sample of PNe to characterize the thermal structure of high-excita…

Exploring the synergies of with MUSE spectroscopy in PHANGS H II regions

Eric Habjan, Kathryn Kreckel, Christopher Faesi +16

Spatially resolved maps of gas-phase metallicity provide key constraints on the chemical enrichment and mixing processes that drive galaxy evolution, but measurements based only on…

The DESIRED electron temperature relations in star-forming regions of the local Universe

M. Orte-García, C. Esteban, J. García-Rojas +7

(Abridged) Aims. We present a homogeneous observational study of electron temperature () relations between ionic species: ([N II]), ([O II]), $T_{\…

The DESIRED strong-line calibrations: I. New empirical metallicity relations for the local and high-redshift universe

F. F. Rosales-Ortega, J. E. Méndez-Delgado, J. U. Guerrero-González +16

We present the most comprehensive set of empirical optical strong-line metallicity calibrations to date, based on the DEep Spectra of Ionised REgions Database (DESIRED), the larges…

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 Martínez-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_{…
