Constraints on the Variation of the Fine-structure Constant at 3 < z < 10 with JWST Emission-line Galaxies

Constraints on the Variation of the Fine-structure Constant at 3 < z < 10 with JWST Emission-line Galaxies

We present constraints on the spacetime variation of the fine-structure constant α at redshifts 2.5 ≤ z  < 9.5 using JWST emission-line galaxies (ELGs). The galaxy sample consists of 621 high-quality spectra with strong and narrow [O  iii ] λλ 4959,5007 doublet emission lines from 578 galaxies, i...
