UNCOVER: Candidate Red Active Galactic Nuclei at 3 < z < 7 with JWST and ALMA

Examples of Sersic profile fits to the F444W image. From left to right: NIRCam SW color image (based on F115W, F150W, F200W), NIRCam LW color image (F277W,F356W,F444W), F444W image, GALFIT best-fit model, residual, and a star scaled to the same flux placed in the residual map. The top row shows an unresolved source modeled with a single Sersic component that is indistinguishable from a star, the middle row shows a source that is better modeled by a two-component PSF+Sersic model, but is dominated by the PSF component. The bottom row shows an extended source without evidence for a bright point source. These are removed from the sample.
