© ESO, 2017. We examine the relation between breaks in the surface brightness profiles and radial abundance gradients within the optical radius in the discs of 134 spiral galaxies from the CALIFA survey. The distribution ...

© 2016 The Authors. We examine the influence of the environment on the chemical abundances of late-type galaxies with masses of 10 9.1 -10 11 M⊙ using data from the Sloan Digital Sky Survey. We find that the environmental ...

© ESO 2015. Spectra of 34 H?II regions in the late-type galaxies NGC 1087, NGC 2967, NGC 3023, NGC 4030, NGC 4123, and NGC 4517A were observed with the South African Large Telescope (SALT). In all 34 H?II regions, oxygen ...

© ESO 2019. We derive rotation curves, surface brightness profiles, and oxygen abundance distributions for 147 late-type galaxies using the publicly available spectroscopy obtained by the MaNGA survey. Changes of the central ...
