Andrew Cooper visited from Durham. He showed us a cutting-edge simulation of galaxy formation. It was impressive to see how distributions of in-situ and accreating stars are different in each halo mass. Thanks Andrew!  Please come back again!

Kevin's Travel in Winter Vacation

 Kevin went to Hokkaido for a tour during the winter vacation. He has experienced the "real" winter which the temperature is about -5~0 degree Celsius. (Comparing with Taiwan's 15~20) 

"A walk" with skiing equipment. 

Looking at the lovely penguins so close!

Bye, New Chitose Airport.

Bye, Hokkaido.
