We present a detailed analysis of the velocity structure of the Virgo cluster using XMM-Newton observations. Using a novel technique which uses uses the Cu Kα instrumental line to calibrate the EPIC-pn energy scale, we are able to obtain velocity measurements with uncertainties down to Δv ∼ 100 km/s. We created 2D projected maps for the velocity, temperature, metallicity, density, pressure and entropy with an spatial resolution of 0.25′. We have found that in the innermost gas there is a high… 

The Merger Dynamics of the X-ray Emitting Plasma in Clusters of Galaxies

As the formation of cosmic structure continues to proceed, we observe one of the latest stages of this process in mergers of clusters of galaxies with other clusters, groups, and galaxies. The X-ray
