Three examples of LOFAR images at 150 MHz of galaxies not classified as extended sources (that is, whose 3σ level contours do not reach a radius of 15″ but whose FWHM, measured by fitting a 2D Gaussian to the central portion of the images, exceeds 15″. The radio contours are superposed to the optical images from Pan-STARRS.
