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…
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-…
Turbulent Pressure Support in the Outer Parts of Galaxy Clusters
Ian J. Parrish, Michael McCourt, Eliot Quataert +1
We use three-dimensional MHD simulations with anisotropic thermal conduction to study turbulence due to the magnetothermal instability (MTI) in the intracluster medium (ICM) of gal…
Thermal Instability & the Feedback Regulation of Hot Halos in Clusters, Groups, and Galaxies
Prateek Sharma, Michael McCourt, Eliot Quataert +1
Observations of clusters and groups imply that such halos are roughly in global thermal equilibrium, with heating balancing cooling when averaged over sufficiently long time- and l…
Cosmological MHD simulations of cluster formation with anisotropic thermal conduction
M. Ruszkowski, D. Lee, M. Bruggen +2
(abridged) The ICM has been suggested to be buoyantly unstable in the presence of magnetic field and anisotropic thermal conduction. We perform first cosmological simulations of ga…
Can conduction induce convection? The non-linear saturation of buoyancy instabilities in dilute plasmas
Michael McCourt, Ian J. Parrish, Prateek Sharma +1
We study the effects of anisotropic thermal conduction on low-collisionality, astrophysical plasmas using two and three-dimensional magnetohydrodynamic simulations. For weak magnet…
