A Systematic Search for Galaxies with Extended Emission Line and Potential Outflows in JADES Medium-Band Images

Understand

For the first time, we present a systematic search for galaxies with extended emission line and potential outflow features using \textit{JWST} medium-band images in the GOODS-S field.

• This is done by comparing the morphology in medium-band images to adjacent continuum and UV bands.
• We look for galaxies that have a maximum extent 50\% larger, an excess area 30\% greater, or an axis ratio difference of more than 0.3 in the medium band compared to the reference bands.
• After visual inspection, we find 326 candidate galaxies at $1.4 < z < 8.4$, with a peak in the population near cosmic noon, benefiting from the good coverage of the medium-band filters.
