What Sets Temperature Gradients in Galaxy Clusters? Implications for non-thermal pressure support and mass-observable scaling relations
Michael McCourt, Eliot Quataert, Ian J. Parrish
We present a spherically symmetric model for the origin and evolution of the temperature profiles in the hot plasma filling galaxy groups and clusters. We find that the gas in clus…
On the Structure of Hot Gas in Halos: Implications for the Lx-Tx Relation & Missing Baryons
Prateek Sharma, Michael McCourt, Ian J. Parrish +1
We present one-dimensional models of the hot gas in dark-matter halos, which both predict the existence of cool cores and explain their structure. Our models are directly applicabl…
Resonance Broadening and Heating of Charged Particles in Magnetohydrodynamic Turbulence
Jacob W. Lynn, Ian J. Parrish, Eliot Quataert +1
The heating, acceleration, and pitch-angle scattering of charged particles by MHD turbulence are important in a wide range of astrophysical environments, including the solar wind,…
The Dynamics of Rayleigh-Taylor Stable and Unstable Contact Discontinuities with Anisotropic Thermal Conduction
Daniel Lecoanet, Ian J. Parrish, Eliot Quataert
We study the effects of anisotropic thermal conduction along magnetic field lines on an accelerated contact discontinuity in a weakly collisional plasma. We first perform a linear…
The Effects of Anisotropic Viscosity on Turbulence and Heat Transport in the Intracluster Medium
Ian J. Parrish, Michael McCourt, Eliot Quataert +1
In the intracluster medium (ICM) of galaxy clusters, heat and momentum are transported almost entirely along (but not across) magnetic field lines. We perform the first fully self-…
