Title: The Astrophysics of extreme feedback in WISE-radio selected AGN

Abstract: This is a continuation of our 2011B and 2012A program to obtain spectra of extremely powerful obscured QSOs with powerful young radio jets. The most luminous and obscured AGN are likely crucial to understanding the processes that establish the mass functions of massive galaxies and their central supermassive blackholes. These short-lived events should show the most powerful feedback at work. By combining the large-area NVSS/FIRST radio surveys with the all-sky WISE infrared (IR) survey, we highlight candidate hyperluminous AGNs by excess radio and mid-IR power. WISE provides estimates of the total mid-IR power of the AGN, while the radio flux highlights the presence of energy and momentum being fed into the interstellar medium (ISM) via powerful radio jets. We have 345GHz ALMA data for half of our sample of 49 targets and SOAR spectra demonstrating that these sources are amongst the most luminous systems known, with one having L_bol over 10^14 L_suns. We seek SOAR imaging and spectra to find redshifts and to derive AGN and star-formation diagnostics of outstanding examples of this sample, many of which have scheduled EVLA and Herschel observations, in addition to the ongoing ALMA observations. Here we request time to observe the 30 remaining targets in our sample in the 3-13 hr range that lack redshifts.
