Multi-wavelength observations of the JWST-dark radio source. Top Left: JWST NIRCam color image (blue: F090W+F115W+F150W; green: F200W+F277W; red: F356W+F410M+F444W) with VLA 3 GHz contours overlaid at 5σ, 15σ, 25σ in yellow, where σ = 2.3 μJy beam⁻¹. Top Middle: the stacked HST ACS (F475W+F606W+F814W) image, JWST MIRI image (F770W+F1280W+F1500W+F1800W+F2100W), and radio imaging data from 144 MHz to 3 GHz with dashed circles indicating the corresponding beam size. Top Right: radio spectral fit, yielding α = −0.99 ± 0.03 for S_ν ∝ ν^α. Bottom: photometric measurements and spectral energy distribution. Gray shadows show the 3σ upper limits from HST, JWST, Herschel, and ALMA, together with the radio detections denoted by black diamonds. Blue circles and lines represent a model SED of a heavily obscured radio-loud AGN (R. Endsley et al. 2023) at z ∼ 7 for comparison.
