Central oxygen abundances in the spiral galaxies of the MaNGA survey: Galaxies with central starbursts

L. S. Pilyugin, G. Tautvaisiene

We examine whether there are deviations of the local central oxygen abundances in spiral galaxies from the general metallicity gradients. We compare the values of the central inter…

Chemical abundances in the dwarf galaxy NGC 4163 based on the nebular and auroral emission lines

I. A. Zinchenko, L. S. Pilyugin

We constructed an oxygen abundance map and N/O ratio map of the unusually low excitation dwarf irregular galaxy NGC 4163 based on publicly available spectroscopy obtained by the Ma…

Metal-THINGS: The association and optical characterization of SNRs with HI holes in NGC 6946

M. A. Lara-Lopez, L. S. Pilyugin, J. Zaragoza-Cardiel +9

NGC~6946, also known as the `Fireworks' galaxy, is an unusual galaxy that hosts a total of 225 supernova remnant (SNR) candidates, including 147 optically identified with high [SII…

Mass-Metallicity and Star Formation Rate in Galaxies: a complex relation tuned to stellar age

S. Duarte Puertas, J. M. Vilchez, J. Iglesias-Páramo +5

In this work we study the stellar mass -- metallicity relation (MZR) of an extended sample of star-forming galaxies in the local Universe and its possible dependence with the star…

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…

Two types of distribution of the gas velocity dispersion of MaNGA galaxies

L. S. Pilyugin, I. A. Zinchenko, M. A. Lara-Lopez +2

The distribution of the gas velocity dispersion sigma across the images of 1146 MaNGA galaxies is analyzed. We find that there are two types of distribution of the gas velocity dis…
