报告摘要

　　Combining cosmological probes offers a powerful route to understanding cosmic expansion, structure growth, and fundamental physics. This requires fast, consistent mocks that capture their cross-correlations. I will present our progress towards an all-in-one mock framework combining galaxy and quasar clustering, the Lyman-alpha forest, and galaxy and cosmic microwave background lensing within a common lightcone. These developments aim to support multi-probe and multi-tracer analyses with next-generation cosmological surveys.

嘉宾简介

　　Cheng Zhao (赵成) is a tenure-track associate professor at Department of Astronomy, Tsinghua University. He received his PhD in astrophysics (2018) from Tsinghua University, and then spent 4 years in Switzerland as a postdoctoral fellow at EPFL. He is mainly engaged in the study of large-scale structures of the Universe based on massive galaxy spectroscopic surveys and high-fidelity cosmological simulations. To this end, he has been a key member of the extended Baryon Oscillation Spectroscopic Survey (eBOSS) and the Dark Energy Spectroscopic Instrument (DESI). He is also co-leading the science team of the MUltiplexed Survey Telescope (MUST).
