Propagation of weak shocks in cool-core galaxy clusters in two-temperature magnetohydrodynamics with anisotropic thermal conduction
S. Komarov, C. Reynolds, E. Churazov
We investigate how different magnetohydrodynamic models of propagation of a weak (Mach number ~1.2) shock in the core of a galaxy cluster affect its observational appearance, using…
Polarization of Sunyaev-Zeldovich signal due to electron pressure anisotropy in galaxy clusters
I. Khabibullin, S. Komarov, E. Churazov +1
We describe polarization of the Sunyaev-Zel'dovich (SZ) effect associated with electron pressure anisotropy likely present in the intracluster medium (ICM). The ICM is an astrophys…
Self-inhibiting thermal conduction in high-beta, whistler-unstable plasma
S. Komarov, A. Schekochihin, E. Churazov +1
A heat flux in a high- plasma with low collisionality triggers the whistler instability. Quasilinear theory predicts saturation of the instability in a marginal state characteri…
Polarization of thermal bremsstrahlung emission due to electron pressure anisotropy
S. Komarov, I. Khabibullin, E. Churazov +1
Astrophysical plasmas are typically magnetized, with the Larmor radii of the charged particles many orders of magnitude smaller than their collisional mean free paths. The fundamen…
Suppression of thermal conduction in a mirror-unstable plasma
S. V. Komarov, E. M. Churazov, M. W. Kunz +1
The ICM plasma is subject to firehose and mirror instabilities at scales of order the ion Larmor radius. The mirror instability generates fluctuations of magnetic-field strength $δ…
Suppression of local heat flux in a turbulent magnetized intracluster medium
S. Komarov, E. Churazov, A. Schekochihin +1
X-ray observations of hot gas in galaxy clusters often show steeper temperature gradients across cold fronts -- contact discontinuities, driven by the differential gas motions. The…
