We detected a compact H$\\alpha$-emitting (i.e., star-forming) region in the galaxy, which has a much smaller angular size [$< 0\".57$ (1.9 kpc) at full width at half maximum (FWHM)] than the extended stellar continuum emission region determined by the Gemini/GMOS z'-band image [$\\simeq 1\".4$ (4.6 kpc) at FWHM with ellipticity b/a=0.45].
