Calibration-based abundances in the interstellar gas of galaxies from slit and IFU spectra
Pilyugin L. S., Lara-Lopez M. A., Vilchez J. M. +3
In this work we make use of available Integral Field Unit (IFU) spectroscopy and slit spectra of several nearby galaxies. The pre-existing empirical R and S calibrations for abunda…
Chemical abundances in Seyfert galaxies -IX. Helium abundance estimates
O. L. Dors, M. Valerdi, P. Freitas-Lemes +7
For the first time, the helium abundance relative to hydrogen (He/H), which relied on direct measurements of the electron temperature, has been derived in the narrow line regions (…
Gas phase metallicity determinations in nearby AGNs with SDSS-IV MaNGA: evidence of metal poor accretion
Janaína C. do Nascimento, Oli L. Dors, Thaisa Storchi-Bergmann +8
We derive the metallicity (traced by the O/H abundance) of the Narrow Line Region ( NLR) of 108 Seyfert galaxies as well as radial metallicity gradients along their galaxy disks an…
