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.
