Spatially resolved studies of galaxies offer critical insights into the physical processes that regulate star formation and stellar mass growth. In this talk, I will present results from the Next Generation Deep Extragalactic Exploratory Public (NGDEEP) Survey, which uses JWST/NIRISS Slitless Spectroscopy to study galaxies at redshifts z ~ 1–3. The deep NGDEEP spectroscopy enables measurements of [OII], [OIII], H-beta, and H-alpha emission features for galaxies with stellar masses of 10^7 solar masses, nearly a factor of a hundred lower than previous studies. I will focus on the spatially resolved H-alpha measurements, as well as integrated and resolved [O III]/[O II] ratios, to explore the connection between star formation, ionization conditions, and stellar mass.

Bio: Lu Shen is currently a postdoctoral researcher at Texas A&M University. She obtained her Ph. D in the University of California, Davis. She then worked as a postdoctoral researcher at the University of Science and Technology of China. Her research focuses on the spatially resolved star formation of galaxies in moderate-to-high redshift, and the role of clusters and protocluster environments on galaxy evolution.
