Research Experience

Ongoing Project:

• Research on Galaxy-Halo Clustering within Cosmic Void using Constrained Simulation
  Department of Astronomy, USTC
  📅 2025.8 – present
  🧑‍🏫 Supervisor: Prof. Huiyuan Wang

  • Project Overview: Investigating the significant discrepancy where observed dwarf galaxy clustering around cosmic voids exceeds theoretical predictions. Utilizing ELUCID constrained simulations to construct halo catalogs that strictly match the SDSS DR7 observational volume for direct comparison.
  • Statistical Analysis: Calculated the Galaxy-Void Two-Point Cross-Correlation Function (2PCCF) to quantify the clustering signal ; extending the analysis to TNG100 hydrodynamic simulations to verify whether standard galaxy formation models can reproduce this anomaly across different mass ranges.
  • Mechanism Study: Exploring the physical origins of the signal by analyzing secondary dependencies (e.g., color, Sérsic index) ; testing the impact of Halo Assembly Bias in low-density environments to refine the galaxy-halo connection model.

• Research on Dark Energy Model Department of Astronomy, USTC

  🧑‍🏫 Supervisor: Prof. Wenjuan Fang

  • Member of the DESI Collaboration: Recently reading 2508.17955 and 2511.05653 for future research.
