No direct coupling between bending of galaxy disc stellar age and light profiles as seen from CALIFA
Published online by Cambridge University Press: 21 March 2017
Extract
Recent theoretical and observational works claim the existence of galaxies with a characteristic age profile consisting on a negative radial trend followed by a smooth age upturn in its outskirts (“U-shape”). This shape has been generally related to down-bending light distributions; however, the existence of a real link between observed Surface Brightness (SB) profiles and changes in stellar properties such as age is still unclear.
