Kavli Affiliate: Linhua Jiang | First 5 Authors: Linhua Jiang, Shuqi Fu, Feige Wang, Sarah E. I. Bosman, Zheng Cai | Summary: We present constraints on the spacetime variation of the fine-structure constant $alpha$ at redshifts $2.5le z<9.5$ using JWST emission-line galaxies. The galaxy sample consists of 621 high-quality spectra with strong and narrow [O […]
