Fig. 1: A distant galaxy spectroscopically confirmed by JADES.
From: Photometric detection at 7.7 μm of a galaxy beyond redshift 14 with JWST/MIRI
This galaxy was initially selected from ultradeep NIRCam and MIRI imaging with JWST (F770W–F277W–F115W shown as an RGB false-colour mosaic in the lower right). It was targeted for NIRSpec micro shutter array follow-up observations and has been spectroscopically confirmed at redshift \(z=14.3{2}_{-0.20}^{+0.08}\)11. JADES-GS-z14-0 is to the right and the foreground galaxy NIRCam ID 183349 to the left. The apparent colour of JADES-GS-z14-0 is caused by the absorption of the NIRCam/F115W flux by the intervening IGM and the rest-frame optical nebular emission-line excess in MIRI/F770W relative to NIRCam/F277W. A scale bar of 0.6" is provided which corresponds to roughly 1.9 physical kpc (pkpc) at the observed redshift (z = 14.32).
