Extreme emission line galaxies (EELGs), where nebular emissions contribute 30%–40% of the flux in certain photometric bands, are ubiquitous in the early Universe ( z > 6). We utilize deep NIRCam imaging from the JWST Advanced Deep Extragalactic Survey ( JADES ) to investigate the properties of companion galaxies (projected distance 6.
