Investigating the Drivers of Electron Temperature Variations in HII Regions with Keck-KCWI and VLT-MUSE
Ryan J. Rickards Vaught, Karin M. Sandstrom, Francesco Belfiore +12
HII region electron temperatures are a critical ingredient in metallicity determinations and recent observations reveal systematic variations in the temperatures measured using dif…
Density biases and temperature relations for DESIRED HII regions
J. E. Méndez-Delgado, C. Esteban, J. García-Rojas +6
We present a first study based on the analysis of the DEep Spectra of Ionized REgions Database (DESIRED). This is a compilation of 190 high signal-to-noise ratio optical spectra of…
Temperature inhomogeneities cause the abundance discrepancy in H II regions
J. Eduardo Méndez-Delgado, César Esteban, Jorge García-Rojas +2
HII regions, ionized nebulae where massive star formation has taken place, exhibit a wealth of emission lines that are the fundamental basis for estimating the chemical composition…
Atomic Data Assessment with PyNeb: Radiative and Electron Impact Excitation Rates for [Fe II] and [Fe III]
Claudio Mendoza, José E. Méndez-Delgado, Manuel Bautista +2
We use the PyNeb 1.1.16 Python package to evaluate the atomic datasets available for the spectral modeling of [Fe II] and [Fe III], which list level energies, A-values, and effecti…
