Research Opportunities in Plasma Astrophysics
Stuart Bale, Amitava Bhattacharjee, Fausto Cattaneo +13
Major scientific questions and research opportunities are described on 10 unprioritized plasma astrophysics topics: (1) magnetic reconnection, (2) collisionless shocks and particle…
Magnetic Helicities and Dynamo Action in Magneto-rotationally Driven Turbulence
G. Bodo, F. Cattaneo, A. Mignone +1
We examine the relationship between magnetic flux generation, taken as an indicator of large-scale dynamo action, and magnetic helicity, computed as an integral over the dynamo vol…
Laboratory evidence of dynamo amplification of magnetic fields in a turbulent plasma
P. Tzeferacos, A. Rigby, A. Bott +27
Magnetic fields are ubiquitous in the Universe. Extragalactic disks, halos and clusters have consistently been shown, via diffuse radio-synchrotron emission and Faraday rotation me…
Numerical modeling of laser-driven experiments aiming to demonstrate magnetic field amplification via turbulent dynamo
P. Tzeferacos, A. Rigby, A. Bott +29
The universe is permeated by magnetic fields, with strengths ranging from a femtogauss in the voids between the filaments of galaxy clusters to several teragauss in black holes and…
Global Properties of Fully Convective Accretion Disks from Local Simulations
G. Bodo, F. Cattaneo, A. Mignone +2
We present an approach to deriving global properties of accretion disks from the knowledge of local solutions derived from numerical simulations based on the shearing box approxima…
A Model of Plasma Heating by Large-Scale Flow
P. Pongkitiwanichakul, F. Cattaneo, S. Boldyrev +2
In this work we study the process of energy dissipation triggered by a slow large scale motion of a magnetized conducting fluid. Our consideration is motivated by the problem of he…
