Welcome to Prof. Sukyoung K. Yi's group (GEM) homepage





The ultimate goal of our group is to understand the formation and evolution of galaxies. We work on various versions of galaxy formation theories, focusing on dynamical clustering of galaxies and galactic chemical evolution in combination with stellar population synthesis. We extensively, but not exclusively, use SDSS and GALEX data to test our theoretical models.

Demography of SDSS early-type galaxies from the perspective of radial color gradients


Explanation: While the majority of massive early-type galaxies show a negative color gradient(red-cored; top), ~30% of the galaxies show a positive color gradient (blue-cored;bottom). These blue-cored galaxies have undergone a recent episode of star formation. This implies that most of the residual star formation in early-type galaxies is centrally concentrated
