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.
Prof. Christophe Pichon at IAP and his group members will visit GEM (12 Feb 2016)

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