The role of the diffuse ionized gas in metallicity calibrations
N. Vale Asari
Estimates of gas-phase abundances based on strong-line methods have been calibrated for H~{\scshape ii} regions. Those methods ignore any contribution from the diffuse ionized gas…
A Machine Learning Approach to Integral Field Unit Spectroscopy Observations: II. HII Region LineRatios
Carter Rhea, Laurie Rousseau-Nepton, Simon Prunet +5
In the first paper of this series (Rhea et al. 2020), we demonstrated that neural networks can robustly and efficiently estimate kinematic parameters for optical emission-line spec…
Identifying radio active galactic nuclei among radio-emitting galaxies
Dorota Kozieł-Wierzbowska, Natalia Vale Asari, Grażyna Stasińska +4
Basing our analysis on ROGUE I, a catalog of over 32,000 radio sources associated with optical galaxies, we provide two diagnostics to select the galaxies where the radio emission…
Clues on the history of early-type galaxies from SDSS spectra and GALEX photometry
Ariel Werle, Roberto Cid Fernandes, Natalia Vale Asari +10
Stellar population studies of early-type galaxies (ETGs) based on their optical stellar continuum suggest that these are quiescent systems. However, emission lines and ultraviolet…
Less than the sum of its parts: the dust-corrected H luminosity of star-forming galaxies explored at different spatial resolutions with MaNGA and MUSE
N. Vale Asari, V. Wild, A. L. de Amorim +10
The H and H emission line luminosities measured in a single integrated spectrum are affected in non-trivial ways by point-to-point variations in dust attenuation in a galaxy.…
Diffuse ionized gas and its effects on nebular metallicity estimates of star-forming galaxies
N. Vale Asari, G. S. Couto, R. Cid Fernandes +5
We investigate the impact of the diffuse ionized gas (DIG) on abundance determinations in star-forming (SF) galaxies. The DIG is characterised using the H equivalent width ($W_{…
