[10.11] Diffuse Radio Emission and Large Scale Structure

L. Rudnick, K.M. Delain (University of Minnesota), S. Rawlings, K. Brand, K. Blundell (University of Oxford)

We present results from a deep, low resolution VLA observation of the TONS 6^o by 6^o field at 90cm, and a possible detection of large scale structure in diffuse radio emission. Other studies have identified >100 Mpc superstructures in this field. We present the results of pushing into the radio confusion limit by subtracting small sources detected at higher resolution. We have removed ~95% of the flux from the small sources using this method. We discuss the prospects of detecting large scale structure through the radio emission expected to be generated by structure formation shocks.
