Biography:
The Cosmic Microwave Background (CMB) radiation is the thermal remnant from when the universe was just 380,000 years old. The CMB radiation is highly uniform and isotropic, but upon closer inspection, traces of primordial quantum fluctuations manifest as variations of a few microkelvins (μK) in the CMB temperature sky map. The study of the statistical patterns in the CMB has laid the foundation for the current standard cosmological model—the ΛCDM model. The CMB still holds a wealth of untapped information. This report will first discuss the scientific significance of future CMB telescopes, then focus on the Ali CMB Polarization Telescope (AliCPT) currently being installed and deployed in Tibet, China.
Abstract:
Yaqiong Li earned her Ph.D. from Princeton University in 2020. From 2020 to 2023, she conducted postdoctoral research at the Kavli Institute, Cornell University. At the end of 2023, she returned to China and joined the Institute of High Energy Physics (IHEP), Chinese Academy of Sciences, as an associate professor.
Her long-term research focuses on the development of focal planes for Cosmic Microwave Background (CMB) telescopes and the analysis of observational data. She specializes in superconducting detector module packaging, testing, signal modulation techniques, and transient source analysis. Since 2014, she has contributed to cutting-edge international CMB projects—such as ACT (Atacama Cosmology Telescope), SO (Simons Observatory), and FYST/CCAT—by developing high-performance cryogenic superconducting detector modules.
