The \emph{JWST} Emission Line Survey (JELS): The sizes and merger fraction of star-forming galaxies during the Epoch of Reionization
We used observations from the \emph{JWST} Emission Line Survey (JELS) to measure the half-light radii ($r_{e}$) of 23 H$α$-emitting star-forming (SF) galaxies at $z=6.1$ in the PRIMER/COSMOS field. Ga...
