Abstract：
Integral field spectroscopy provides a powerful way to study the spatially resolved properties of galaxies, including stellar populations, ionized gas, chemical abundances, and kinematics. In this talk, I will introduce three complementary instruments: CHILI on the Lijiang 2.4-m Telescope, the Integral Field Spectrograph onboard the China Space Station Telescope (CSST-IFS), and CUBWISE, a proposed blue-optimized wide-field IFS for the future 14.5-m telescope. I will highlight science applications enabled by their different strengths. CHILI provides a flexible platform for nearby-galaxy studies; CSST-IFS will exploit space-based high angular resolution to resolve compact physical structures; and CUBWISE will combine large collecting area, wide field of view, and strong blue sensitivity to probe weak diagnostic lines and low-surface-brightness structures. Together, these efforts are building a sustained capability in integral field spectroscopy in China, spanning instrumentation, observations, and scientific exploitation.

Biography:
Dr. Lei Hao is a Professor at the Shanghai Astronomical Observatory, Chinese Academy of Sciences. Her research focuses on galaxy evolution, supermassive black holes, and spatially resolved spectroscopy. She serves as the Science Lead of the Integral Field Spectrograph onboard the China Space Station Telescope (CSST-IFS) and is the Principal Investigator of CHILI, the first integral field spectrograph developed in China for nighttime astronomical observations. She is also leading the development of CUBWISE, a next-generation, blue-optimized wide-field integral field spectrograph proposed for China’s future 14.5-m optical/infrared telescope. Her work bridges astrophysical research and the development of advanced spectroscopic instrumentation.
