Dr. Heng Yu is an associate professor of the department of Astronomy.

He got his Ph.D. in Astronomy at the Beijing Normal University in

2011, with a thesis on "The study of X-ray galaxy clusters and its

cosmological applications". In 2009 and 2010, he spent two years at

the Osservatorio Astronomico di Trieste, Italy. In 2014, he worked as

a post-doctoral fellow at the University of Torino.

His main research interest is using multi-wavelength (optical, X-ray,

radio) data to study the physics of galaxy clusters.

He develop a X-ray redshift measurement technique and a hierarchical

substructures identification method -- blooming tree analysis to

explore dynamical status of clusters, expeciallly the radial movement.

A joint analysis of them can unveil inner structures of clusters and

trace their merging proccess.
