Abstract

The study of spiral galaxies has yielded fruitful results over the past half-century. The metallicity of a galaxy, the ratio of metal elements to hydrogen and helium, has been shown to decrease as the distance to the center of the galaxy increase. This study verifies the metallicity distribution of Sc type galaxies, with more definite metallicity gradients. In this paper, the author utilized the SDSS-IV MaNGA survey to plot out the metallicity gradient calculated with the O3N2 calibrator. The result shows a large amount of scattering after a certain distance, and that the metallicity gradient is mostly flat, with the exception of a number of galaxies. This shows that the metallicity gradient conforms with the traditional view. The scattering can be explained by the spiral structure of the galaxy, and the exceptions may be due to the observational issues or higher redshifts, which has demonstrated a positive metallicity gradient. These results allowed the confirmation of the metallicity gradient at lower redshifts, and it has given more insight into the metallicity distribution of Sc type galaxies, and thus more insight into the formation of spiral galaxies.
