The impact of astrophysical dust grains on the confinement of cosmic rays
Jonathan Squire, Philip F Hopkins, Eliot Quataert +1
We argue that charged dust grains could significantly impact the confinement and transport of galactic cosmic rays. For sub-GeV to ~1000GeV cosmic rays, small-scale parallel Alfvén…
Sound-Wave Instabilities in Dilute Plasmas with Cosmic Rays: Implications for Cosmic-Ray Confinement and the Perseus X-ray Ripples
Philipp Kempski, Eliot Quataert, Jonathan Squire
Weakly collisional, magnetised plasmas characterised by anisotropic viscosity and conduction are ubiquitous in galaxies, halos and the intracluster medium (ICM). Cosmic rays (CRs)…
Thermal Instability of Halo Gas Heated by Streaming Cosmic Rays
Philipp Kempski, Eliot Quataert
Heating of virialized gas by streaming cosmic rays (CRs) may be energetically important in galaxy halos, groups and clusters. We present a linear thermal stability analysis of plas…
The MASSIVE Survey XIII -- Spatially Resolved Stellar Kinematics in the Central 1 kpc of 20 Massive Elliptical Galaxies with the GMOS-North Integral-Field Spectrograph
Irina Ene, Chung-Pei Ma, Nicholas J. McConnell +5
We use observations from the GEMINI-N/GMOS integral-field spectrograph (IFS) to obtain spatially resolved stellar kinematics of the central kpc of 20 early-type galaxies (…
Shearing-box simulations of MRI-driven turbulence in weakly collisional accretion discs
Philipp Kempski, Eliot Quataert, Jonathan Squire +1
We present a systematic shearing-box investigation of MRI-driven turbulence in a weakly collisional plasma by including the effects of an anisotropic pressure stress, i.e. anisotro…
