ZINGRS: Further understanding Hot DOGs via the Radio Continuum of galaxy W2246-0526
Abstract
We have recently observed W2246-0526 at z~4.6 with the Jansky Very Large Array as a part of the ZINGRS Radio Survey. The ZINGRS Radio Survey provides measurements of thermal free-free and non-thermal radio emission of sources from the ZEUS Investigated Galaxy Reference Sample. The survey lets us investigate the evolution of the radio continuum at high redshift and metallicity when combined with far-IR fine-structure line emission observed with ZEUS. W2246-0526 is a Hot dust obscured galaxy (Hot DOG) with active star formation along with an active galactic nucleus (AGN). It is the most luminous, un-lensed galaxy in the universe so far detected, allowing us to pilot our investigation of the radio continuum and metallicity spatially across the source. This past summer we reduced and analyzed 40 total hours of C, Ku, and Ka-band (5GHz, 15GHz and 32 GHz respectively) data revealing complex radio emission from multiple galaxies. Here we present the images, and our initial analysis of the radio continuum from galaxy W2246.
