We investigate the observational signatures and physical origin of ram-pressure stripping (RPS) in 63 massive galaxy clusters at z = 0.3–0.7, based on images obtained with the Hubble Space Telescope. Using a training set of a dozen ‘jellyfish’ galaxi... Read More about Jellyfish: The origin and distribution of extreme ram-pressure stripping events in massive galaxy clusters.

Deep Chandra observation and numerical studies of the nearest cluster cold front in the sky (2015)
Journal Article
Werner, N., ZuHone, J. A., Zhuravleva, I., Ichinohe, Y., Simionescu, A., Allen, S. W., Markevitch, M., Fabian, A. C., Keshet, U., Roediger, E., Ruszkowski, M., & Sanders, J. S. (2016). Deep Chandra observation and numerical studies of the nearest cluster cold front in the sky. Monthly notices of the Royal Astronomical Society, 455(1), 846-858. https://doi.org/10.1093/mnras/stv2358

We present the results of a very deep (500 ks) Chandra observation, along with tailored numerical simulations, of the nearest, best resolved cluster cold front in the sky, which lies 90 kpc (19 arcmin) to the north-west of M 87. The northern part of... Read More about Deep Chandra observation and numerical studies of the nearest cluster cold front in the sky.

S., Pandey-Pommier, M., Randall, S., Churazov, E., Bonafede, A., Kraft, R., David, L., Andrade-Santos, F., Merten, J., Zitrin, A., Umetsu, K., Goulding, A., …Vikhlinin, A. (2015). Frontier fields clusters: Chandra and JVLA view of the pre-merging cluster MACS J0416.1-2403. The Astrophysical journal, 812(2), 153. https://doi.org/10.1088/0004-637X/812/2/153

Merging galaxy clusters leave long-lasting signatures on the baryonic and non-baryonic cluster constituents, including shock fronts, cold fronts, X-ray substructure, radio halos, and offsets between the dark matter (DM) and the gas components. Using... Read More about Frontier fields clusters: Chandra and JVLA view of the pre-merging cluster MACS J0416.1-2403.

Stripped elliptical galaxies as probes of ICM physics: I. Tails, wakes, and flow patterns in and around stripped ellipticals (2015)
Journal Article
Roediger, E., Kraft, R. P., Nulsen, P. E. J., Forman, W. R., Machacek, M., Randall, S., Jones, C., Churazov, E., & Kokotanekova, R. (2015). Stripped elliptical galaxies as probes of ICM physics: I. Tails, wakes, and flow patterns in and around stripped ellipticals. The Astrophysical journal, 806(1), Article ARTN 103. https://doi.org/10.1088/0004-637X/806/1/103

Elliptical cluster galaxies are progressively stripped of their atmospheres due to their motion through the intra-cluster medium (ICM). Deep X-ray observations reveal the fine-structure of the galaxy's remnant atmosphere and its gas tail and wake. Th... Read More about Stripped elliptical galaxies as probes of ICM physics: I.

Stripped elliptical galaxies as probes of ICM physics: II. Stirred, but mixed? Viscous and inviscid gas stripping of the Virgo elliptical M89 (2015)
Journal Article

Elliptical galaxies moving through the intra-cluster medium (ICM) are progressively stripped of their gaseous atmospheres. X-ray observations reveal the structure of galactic tails, wakes, and the interface between the galactic gas and the ICM. This...
