Jiaxin Han

Jiaxin Han is an associate professor in the Department of Astronomy at Shanghai Jiao Tong University. His research focuses on dark matter, utilizing high-performance numerical simulations and advanced statistical analysis to study its properties and distribution. His work explores dark matter halos, including their formation, substructures, and large-scale distributions, and applies observational techniques such as gravitational lensing and dynamics modeling to investigate dark matter's role in the universe. Han has published extensively in leading journals such as MNRAS and has contributed to projects like HBT+ and the orbital PDF framework. His research aims to uncover the nature of dark matter through interdisciplinary approaches.

Jiaxin Han is a researcher in the Department of Astronomy at Shanghai Jiaotong University, focusing on cosmology and dark matter. Their work explores the evolution of galaxy-dark matter connections, subhalo detection, and the assembly of galaxies within dark matter halos. Han has contributed to the development of algorithms for identifying subhaloes and merger trees in cosmological simulations, as well as studies on the mass distribution of dark matter halos and the dynamics of satellite galaxies. Their research also addresses the constraints on dark matter halo masses using dynamical tracers and weak lensing techniques. Han's publications highlight the importance of understanding the interplay between dark matter and galaxy formation in the context of cosmological simulations.
