Astronomy Colloquium (2015 Spring Semester)

* Date
June 4
* Speaker
Prof. HoSeong Hwang (KIAS)
* Title
Mapping the Large-Scale Structure around Galaxy Clusters
* Abstract
Galaxy Clusters, the largest gravitationally bound systems in the universe, are important tracers of large-scale structure. I will briefly review the history of galaxy redshift surveys focusing on clusters of galaxies, and discuss the results on the comparison of the matter distribution from our MMT/Hectospec cluster redshift surveys with that from weak-lensing surveys.
