Four configurations of the distribution of spaxels with spectra of different BPT types in the circumnuclear regions of cSB galaxies. The BPT radiation types for individual spaxels are colour-coded. The yellow circle shows the kinematic centre of the galaxy, the line indicates a position of the major kinematic axis of the galaxy, and the ellipse is the optical radius. -- astro-ph.GA

Central Oxygen Abundances In The Spiral Galaxies Of The MaNGA Survey: Galaxies With Central Starbursts

by Keith CowingJuly 12, 2024July 7, 2024

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