معرفی
Ting Li is an Assistant Professor in the Department of Astronomy & Astrophysics at the University of Toronto. Her research focuses on near-field cosmology, specifically studying stars in the Milky Way and nearby galaxies to understand galactic formation and dark matter properties. She leads the Southern Stellar Stream Spectroscopic Survey (S5), which maps stellar streams in the Southern Hemisphere to determine the Milky Way's mass profile. Li is also involved in major projects like the Dark Energy Survey (DES) and Dark Energy Spectroscopic Instrument (DESI), contributing to large-scale sky surveys and optical instrumentation.
Li holds a Ph.D. from Texas A&M University (2016) and has pioneered infrastructure for surveys like DESI. She co-chairs the Maunakea Spectroscopic Explorer’s Dark Matter Working Group and convenes the DES Milky Way Working Group. Her work bridges observational astronomy with computational analysis of vast datasets from modern telescopes.
Her research emphasizes analyzing tidal stellar streams, globular clusters, and ultra-faint dwarf galaxies to uncover galactic evolution and dark matter distribution. Collaborations include DELVE (DECam Local Volume Exploration), which has discovered new Milky Way satellites, and S5’s detailed chemical and kinematic studies of stellar debris.
Recent publications focus on baryon acoustic oscillations, Milky Way mass estimation, and the dynamics of satellite galaxies. Li’s contributions span instrumentation (e.g., DESI’s spectrographs) and theoretical modeling of galactic potentials. Her findings inform cosmological parameters and galaxy formation theories.
