The JWST/PASSAGE Survey: Metallicity Radial Gradients in Emission-Line Galaxy Pairs at Cosmic Noon with NIRISS
Using JWST/NIRISS slitless spectroscopy from the PASSAGE program, we analyze 17 spectroscopically confirmed emission-line galaxies in candidate interacting systems at $z \sim 1.7$--$3.2$. These galaxies span stellar masses of $7.3 \lesssim \log(M_*/M_\odot) \lesssim 10.4$ and global gas-phase metallicities of $12+\log(...
