A comprehensive view of a strongly lensed planck-associated submillimeter galaxy.

Abstract: We present hig h-resolutio n maps of stars, dust, and molecular gas in astrongl y le nsed submillimeter galaxy (SMG) at z = 3.259. HATLAS J11 4637.9- 00 1132 is se lecte d from the Hersche/-Astrophysical Te rahertz Large Area Survey CH-ATLAS) as a strong le ns cand idate mainly based on its unusually hig h 500 µ.m flux density (~ 300 mJy ). It is the only hig h-red shift Plan ck detection in the 130 deg 2 H-ATLAS Phase-I area. Keck Adaptive Optic s images revea! a quadruply im aged galaxy in the K band while the Submillimeter Array and the Jansky Yery Large Array showdoubly im aged 880 µ.m and CO(I O) so urces, indicating differentiated dis tributions of the variou s compone nts in the galaxy. In the source pla ne, 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 northea st of the stars. The emissions from the stars, dust, and gas are mag nified by ~ 17 , ~ 8 , and ~ 7 times, respectively, by four len s ing ga la xies at z ~ 1. Intrinsically, the lensed galaxy is a warm (T:iust ~ 40-65 K), hyper­ luminous ( LIR ~ 1. 7 x 10 13 L0 ; star formation rate (SFR) ~ 2000 M0 yr- 1), gas-ric h (Mgas/ Mb aryon ~ 70 %), young (Mstellar/ S í-R ~ 20 Myr), and short-lived (Mgas/ SFR ~ 40 Myr) starburst. .Vith physical properties simi lar to unlensed z > 2 S MGs, HATLAS J1 14 6 3 7.9 - 001132 o ffers a detailed view of a typical SMG throug h a powerful co s mic microscope.
