Lyα narrowband image extracted using a 25 Å wide band centered on the approximate centroid of the Lyα emission. The cross represents the brightest pixel, which is the assumed AGN position, and corresponds to the Δα = 0″, Δδ = 0″ position. The dashed circle represents the upper limit on the size of the radio emission under the same assumption of AGN position. The green contours represent the 2σ detection limits. The image has been smoothed with a Gaussian 2D kernel.
