A textbook example of ram-pressure stripping in the Hydra A/A780 cluster. Astronomy and Astrophysics, 592, A154. https://doi.org/10.1051/0004-6361/201526641

In the current epoch, one of the main mechanisms driving the growth of galaxy clusters is the continuous accretion of group-scale halos. In this process, the ram pressure applied by the hot intracluster medium on the gas content of the infalling grou...

Cold fronts: probes of plasma astrophysics in galaxy clusters (2016)
Journal Article
ZuHone, J. A., & Roediger, E. (2016). Cold fronts: probes of plasma astrophysics in galaxy clusters. Journal of Plasma Physics, 82(3), 535820301-1-535820301-48. https://doi.org/10.1017/s0022377816000544

The most massive baryonic component of galaxy clusters is the “intracluster medium” (ICM), a diffuse, hot, weakly magnetized plasma that is most easily observed in the X-ray band. Despite being observed for decades, the macroscopic transport properti... Read More about Cold fronts: probes of plasma astrophysics in galaxy clusters.

The Hubble Space Telescope Frontier Fields cluster MACS J1149.6+2223 is one of the most complex merging clusters, believed to consist of four dark matter halos. We present results from deep (365 ks) Chandra observations of the cluster, which reveal t...

Jupiter's X-ray auroral emission in the polar cap region results from particles which have undergone strong field-aligned acceleration into the ionosphere. The origin of precipitating ions and electrons and the time variability in the X-ray emission...
