Chemical abundance of LINER galaxies -- Metallicity calibrations based on SDSS-IV MaNGA
C. B. Oliveira, A. C. Krabbe, J. A. Hernandez-Jimenez +5
The ionizing source of Low Ionization Nuclear Emission Regions (LINERs) is uncertain. Because of this, an empirical relation to determine the chemical abundances of these objects h…

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 (…
