CHI ZHANG, 张 弛

I’m a Ph.D. student at Purple Mountain Observatory (PMO) and the University of Science and Technology of China (USTC), advised by Profs. Yi-Zhong Fan and Yue-Lin Sming Tsai. I’m currently a visiting Ph.D. student at SISSA, working with Prof. Matteo Viel. My reaserch interest focus on investigating the nature of dark matter through cosmologycal data and simulations.

About Me

I was born in Ulanqab, a small, beautiful city in the heart of Inner Mongolia—famous for its delicous lamb and endless grasslands. I grew up under clear skies and the mild wind, learning to be free and to keep asking questions. That wonder never left. I began my undergraduate in Physics at Inner Mongolia University in 2017 and, four years later in 2021, entered the Ph.D. program at PMO and USTC via postgraduate recommendation.

Research

Constraints of Mirror Twin Higgs model

A Comprehensive Study Constraining the Mirror Twin Higgs Model Using Weak Gravitational Lensing Data from the DES.

Constraints of DM-baryon interactions

We use weak-lensing data and a nonlinear power-spectrum emulator—trained on our own N-body simulations—to test DM–baryon interactions.

Paper links

Exploring DM-neutrino interactions

We investigate the DM-neutrino interactions via a joint constrain using weak lensing data from DES and CMB data from ACT.
