| Description |
Using data from the NASA Wide-field Infrared Survey Explorer (WISE) mission coupled with deep optical spectroscopy, we have discovered a new population of dusty zvirgul2 galaxies surrounded by large spatially extended Lyman-alphaemission (40-100kpc). These galaxies have redder mid-IR colors than any other high-z dusty populations, inferred IR luminosities of L_FIR>10^13, are unlensed, and are experiencing intense AGN/supernova feedback. These unique properties, and rarity on the sky, make them strong candidates for being one of the ..missing links. in the evolution of massive ellipticals. They have opened up a new regime where spatially extended Ly-alpha and large amounts of dust are likely linked at the key transition from a dusty starburst to a QSO. We request 5.6 hours to obtain Herschel-PACS and SPIRE imaging of *all* 18 spectroscopically confirmed WISE Ly-alpha blobs. Herschel is the only facility that fully probes the peak of the bolometric emission at this redshift. These observations are required in order to 1) derive precise FIR luminosities 2) place robust constraints on the starburst and AGN components 3) study how feedback effects the shape of far-IR seds at high-z 4) uncover what is driving the winds responsible for powering the Ly-alpha clouds around these dusty galaxies and 5) place this new class of extreme object in context with the other well studied zvirgul2 dusty galaxies. |
