GEM
 

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.

  • Title: Sussing merger trees: the impact of halo merger trees on galaxy properties in a semi-analytic model


    Explanation: A halo merger tree forms the essential backbone of a semi-analytic model for galaxy formation and evolution. This study inviestigates effect of various tree building algorithms on galaxy properties using a SAM. Full text [ADS] [국문요약]
