Cross-Correlation of Diffuse Synchrotron and Large-Scale Structures (2009)
Brown, Shea, Farnsworth, Damon, Rudnick, Lawrence
We explore for the first time the method of cross-correlation of radio synchrotron emission and tracers of large-scale structure in order to detect the diffuse IGM/WHIM. We performed a...
Detecting Magnetic Fields in Large-Scale Structure with Radio Polarization (2008)
Brown, Shea, Rudnick, Lawrence, Farnsworth, Damon
We present our attempts to detect magnetic fields in filamentary large-scale structure (LSS) by observing polarized synchrotron emission emitted by structure formation shocks. Little is known about...
Diffuse cluster-like radio emission in poor environments (2008)
Brown, Shea, Rudnick, Lawrence
We present a study of the spectral, polarimetric, morphological and environmental properties of the diffuse radio source 0809+39 using observations taken with the Westerbork Synthesis Radio...
The Discovery of Diffuse Radio Polarization Structures in the NVSS (2008)
Rudnick, Lawrence, Brown, Shea
We have developed a method for recovering polarization structures from the NRAO Very Large Array Sky Survey (NVSS) on larger angular scales than the nominal 15 arc minute survey limit. The technique...
Extragalactic Radio Sources and the WMAP Cold Spot (2007)
Rudnick, Lawrence, Brown, Shea, Williams, Liliya R.
We detect a dip of 20-45% in the surface brightness and number counts of NVSS sources smoothed to a few degrees at the location of the WMAP cold spot. The dip has structure on scales of approximately...
