abstract
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 mu m flux density (similar to 300 mJy). It is the only high-redshift Planck detection in the 130 deg(2) 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 mu m 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 similar to 1.6 kpc, the dust in a compact (similar to 1 kpc) region similar to 3 kpc north of the stars, and the cold molecular gas in an extended (similar to 7 kpc) disk similar to 5 kpc northeast of the stars. The emissions from the stars, dust, and gas are magnified by similar to 17, similar to 8, and similar to 7 times, respectively, by four lensing galaxies at z similar to 1. Intrinsically, the lensed galaxy is a warm (T-dust similar to 40-65 K), hyperluminous (L-IR similar to 1.7 x 10(13) L-circle dot; star formation rate (SFR) similar to 2000 M-circle dot similar to yr(-1)), gas-rich (M-gas/M-baryon similar to 70%), young (M-stellar/SFR similar to 20 Myr), and short-lived (M-gas/SFR similar to 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.
