The XMM Large-Scale Structure Survey (XMM-LSS) is a major project to map the large-scale structure of the universe out to cosmological distances. An 8 deg. x 8 deg. region will be surveyed by XMM with planned optical follow-up to produce a three-dimensional map of many hundreds of clusters out to a redshift of z - 1. To explore the relation of the large-scale structure to the location and properties of ...

High resolution, low frequency observations are very efficient for surveying radio galaxies because of: 1) the wide field of view and 2) the bias toward steep spectrum (lobe dominated) emission. Here I present preliminary results from two ongoing low frequency radio surveys: the 4 Meter All Sky Survey (4MASS) and the low frequency counterpart to the XMM-Large Scale Structure (XMM-LSS) survey. 4MASS is an NRL-NRAO project to survey the entire ...
