Spiral galaxies with flat radial abundance gradients at large radii
L. S. Pilyugin, G. Tautvaisiene
We consider the oxygen abundance distributions for a sample of massive spiral galaxies from the MaNGA survey in which the radial abundance gradient flattens to a constant value out…

Two sequences of spiral galaxies with different shapes of the metallicity gradients
L. S. Pilyugin, G. Tautvaisiene
We considered two sequences of spiral galaxies with different shapes of the radial gas-phase oxygen abundance distributions from the galaxies in the MaNGA survey: (1) Galaxies in w…
