Selection of postage stamp images of the candidate z ∼ 7.7 RL AGN, COSW-106725. Top row, from left to right: HSC-g, HST Advanced Camera for Surveys F814W, JWST F115W. Middle row: JWST F150W, JWST F277W, JWST F444W. Bottom row: JWST MIRI F770W, ALMA 343 GHz, and VLA 1.4 GHz. The ALMA extent is overlaid on each image (in white). The 3σ upper limits are reported for the non-detections. The upper left source in the UV/Optical/NIR images is a low-z interloper (Weaver et al. 2022).
