We present high-resolution maps of stars, dust, and molecular gas in a strongly lensed submillimeter galaxy (SMG) at z = 3.259. HATLAS J114637.9-001132 is selected from the Herschel-Astrophysical Terahertz Large Area Survey (H-ATLAS) as a strong lens candidate mainly based on its unusually high 500 µm flux density (∼300 mJy). It is the only high-redshift Planck detection in the 130 deg² H-ATLAS Phase-I area. Keck Adaptive Optics images reveal a quadruply imaged galaxy in the K band while the Submillimeter Array and the Jansky Very Large Array show doubly imaged 880 µm and CO(1 -> 0) sources, indicating differentiated distributions of the various components in the galaxy. In the source plane, the stars reside in three major kpc-scale clumps extended over ∼1.6 kpc, the dust in a compact (∼1 kpc) region ∼3 kpc north of the stars, and the cold molecular gas in an extended (∼7 kpc) disk ∼5 kpc northeast of the stars. The emissions from the stars, dust, and gas are magnified by ∼17, ∼8, and ∼7 times, respectively, by four lensing galaxies at z ∼ 1. Intrinsically, the lensed galaxy is a warm (T_dust∼ 40-65 K), hyper-luminous (L_IR∼ 1.7x10¹³ L_☉; star formation rate (SFR) ∼2000 M_☉/yr), gas-rich (M_gas/M_baryon∼ 70%), young (M_stellar/SFR ∼ 20 Myr), and short-lived (M_gas/SFR ∼ 40 Myr) starburst. With physical properties similar to unlensed z > 2 SMGs, HATLAS J114637.9-001132 offers a detailed view of a typical SMG through a powerful cosmic microscope.
