Heng Yu


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.
