AbstractWe present an Atacama Large Millimeter/submillimeter Array observation of the Submillimeter galaxy ID 141 at z = 4.24 in the [N II] 205 mu m line (hereafter [N II]) and the underlying continuum at (rest-frame) 197.6 mu m. Benefiting from lensing magnification by a galaxy pair at z = 0.595, ID 141 is one of the brightest z > 4 SMGs. At the angular resolutions of similar to 1.'' 2-1.'' 5 (1 '' similar to 6.9 kpc), our observation clearly separates and moderately resolves the two lensed images in both continuum and line emission at a signal-to-noise ratio >5. Our continuum-based lensing model implies an averaged amplification factor of similar to 5.8 and reveals that the delensed continuum image has a Sersic index similar or equal to 0.95 and Sersic radius of similar to 0.'' 18 (similar to 1.24 kpc). Furthermore, the reconstructed [N II] velocity field in the source plane is dominated by a rotation component with a maximum velocity of similar to 300 km s(-1) at large radii, indicating a dark matter halo mass of similar to 10(12)M(circle dot). This, together with the reconstructed velocity dispersion field being smooth and modest in value (<100 km s(-1)) over much of the outer parts of the galaxy, favors the interpretation of ID 141 being a disk galaxy dynamically supported by rotation. The observed [N II] /CO (7-6) and [N II] /[C II] 158 mu m line-luminosity ratios, which are consistent with the corresponding line ratio versus far-infrared color correlation from local luminous infrared galaxies, imply a delensed star formation rate of (1.8 +/- 0.6) x 10(3)M(circle dot) yr(-1) and provide an independent estimate of the size of the star-forming region 0.7(-0.3)(+0.3) kpc in radius.
