The dependence of the gradients of oxygen and nitrogen-to-oxygen on stellar age in MaNGA galaxies
I. A. Zinchenko, J. M. Vilchez, E. Perez-Montero +3
We derive the oxygen abundance (O/H), the nitrogen-to-oxygen (N/O) abundance ratio, and their corresponding radial gradients for a sample of 1431 galaxies from MaNGA DR15 survey us…
MaNGA galaxies with off-centered spots of enhanced gas velocity dispersion
L. S. Pilyugin, B. Cedres, I. A. Zinchenko +8
Off-centered spots of the enhanced gas velocity dispersion, s, are revealed in some galaxies from the MaNGA survey. Aiming to clarify the origin of the spots of enhanced s, we exam…
Chemical Abundance of the LINER galaxy UGC 4805 with SDSS-IV MaNGA
A. C. Krabbe, C. B. Oliveira, I. A. Zinchenko +5
Chemical abundance determinations in Low-Ionization Nuclear Line Regions (LINERs) are especially complex and uncertain because the nature of the ionizing source of this kind of obj…
