Numerical experiments on dynamo action in sheared and rotating turbulence
T. A. Yousef, T. Heinemann, F. Rincon +5
Numerical simulations of forced turbulence in elongated shearing boxes are carried out to demonstrate that a nonhelical turbulence in conjunction with a linear shear can give rise…
Nonlinear growth of firehose and mirror fluctuations in turbulent galaxy-cluster plasmas
A. A. Schekochihin, S. C. Cowley, R. M. Kulsrud +2
In turbulent high-beta astrophysical plasmas (exemplified by the galaxy cluster plasmas), pressure-anisotropy-driven firehose and mirror fluctuations grow nonlinearly to large ampl…
Astrophysical gyrokinetics: kinetic and fluid turbulent cascades in magnetized weakly collisional plasmas
A. A. Schekochihin, S. C. Cowley, W. Dorland +4
We present a theoretical framework for plasma turbulence in astrophysical plasmas (solar wind, interstellar medium, galaxy clusters, accretion disks). The key assumptions are that…
Numerical demonstration of fluctuation dynamo at low magnetic Prandtl numbers
A. B. Iskakov, A. A. Schekochihin, S. C. Cowley +2
Direct numerical simulations of incompressible nonhelical randomly forced MHD turbulence are used to demonstrate for the first time that the fluctuation dynamo exists in the limit…
Fast growth of magnetic fields in galaxy clusters: a self-accelerating dynamo
A. A. Schekochihin, S. C. Cowley
We propose a model of magnetic-field growth in galaxy clusters whereby the field is amplified by a factor of about 10^8 over a cosmologically short time of ~10^8 yr. Our model is b…
A Hot Helium Plasma in the Galactic Center Region
R. Belmont, M. Tagger, M. Muno +2
Recent X-ray observations by the space mission Chandra confirmed the astonishing evidence for a diffuse, hot, thermal plasma at a temperature of 9. K (8 keV) found by previo…
