Understanding shape and centroid deviations in 39 strong lensing galaxy clusters in various dynamical states [PDF]
EPJ Web of ConferencesThrough observational tests of strong lensing galaxy clusters, we can test simulation derived structure predictions that follow from Λ Cold Dark Matter (ΛCDM) cosmology.

NGC 7421: Surfing the Intracluster Medium?
, 1997 NGC 7421 is a barred spiral that is displaced from the centre of its optical envelope, and has a ‘bow-shock’-like western boundary, both suggestive of interaction with an intracluster medium.

The Magnetothermal Instability in the Intracluster Medium [PDF]
The Astrophysical Journal, 2008 The electron mean free path in the intracluster medium (ICM) of galaxy clusters is much larger than the gyroradius; thus, heat is transported anisotropically along magnetic field lines. We show that the intracluster medium is unstable to the magnetothermal instability (MTI) using MHD simulations with anisotropic thermal conduction.

Resolved magnetic dynamo action in the simulated intracluster medium [PDF]
, 2017 Faraday rotation and synchrotron emission from extragalactic radio sources give evidence for the presence of magnetic fields extending over ˜ Mpc scales. However, the origin of these fields remains elusive.

The Impact of Radio AGN Bubble Composition on the Dynamics and Thermal Balance of the Intracluster Medium [PDF]
Astrophysical Journal, 2018 Feeding and feedback of active galactic nuclei (AGNs) are critical for understanding the dynamics and thermodynamics of the intracluster medium (ICM) within the cores of galaxy clusters.

Cosmic-Ray Feedback Heating of the Intracluster Medium [PDF]
, 2017 Active galactic nuclei (AGNs) play a central role in solving the decades-old cooling-flow problem. Although there is consensus that AGNs provide the energy to prevent catastrophically large star formation, one major problem remains: How is the AGN energy

THE NON-THERMAL INTRACLUSTER MEDIUM [PDF]
The Astrophysical Journal, 2010 WMAP's detection of the Sunyaev-Zel'dovich effect at a much reduced level among several large samples of rich clusters is interpreted in terms of conventional physics. It has been suggested that the central soft X-ray and EUV excess found in some clusters cannot be of thermal origin, due to problems with rapid gas cooling and the persistent non ...
