A pair of non-contact EMATs has been used for thickness measurements and imaging of metallic plates. This was performed using wide bandwidth EMATs and pulsecompression signal processing techniques, using chirp excitation. This gives a greatly improved Signal to Noise Ratio (SNR) for non-contact experiments, increasing the speed of data acquisition. A numerical simulation of the technique has co...

Among the biggest surprises revealed by COBE and confirmed by WMAP measurements of the temperature anisotropy of the CMB are the anomalous features in the 2-point angular correlation function on very large angular scales. In particular, the l = 2 quadrupole and l = 3 octopole terms are surprisingly planar and aligned with one another, which is highly unlikely for a statistically isotropic Gauss...

Using a novel suite of cosmological simulations zooming in on Mpc-scale intergalactic sheet or "pancake" at z~3-5, we conduct an in-depth study the thermal properties and HI content warm-hot medium (WHIM) those redshifts. The span nearly three orders magnitude gas-cell mass, from ~(7.7x10^6-1.5x10^4)Msun, one highest resolution such large patch inter-galactic (IGM) to date. At z~5, strong accre...
