a: EVN 1.6 GHz VLBI image of the field associated with J123600.10 (undetected). The white cross on the map presents the position of the source as measured in the re-processed eMERGE image. The map size corresponds to the 2σ uncertainties in the VLA position. This image was plotted with contour levels −3 and 3× the rms noise level. b: Hubble NICMOS NIC2 F160W image of J123600 in which the source shows a disc-like structure with close projected companions. For clarity, the image was smoothed with a 2D Gaussian convolution with a FWHP of ∼0.15″. The overlaid contour was plotted at 3, 6, 12, and 24× the rms noise level of the eMERGE-JVLA moderate resolution image at 1.5 GHz. The red box shows the FoV of (a). As shown in (b), the radio and optical images have similar morphologies with reasonable position offset of ∼0.7″. In each panel, the beam pattern of the contours is illustrated with a black ellipse.
