The Pencil Code, a modular MPI code for partial differential equations and particles: multipurpose and multiuser-maintained
A. Brandenburg, A. Johansen, P. A. Bourdin +34
The Pencil Code is a highly modular physics-oriented simulation code that can be adapted to a wide range of applications. It is primarily designed to solve partial differential equ…
Stabilizing effect of magnetic helicity on magnetic cavities in the intergalactic medium
Simon Candelaresi, Fabio Del Sordo
We investigate the effect of magnetic helicity on the stability of buoyant magnetic cavities as found in the intergalactic medium. In these cavities, we insert helical magnetic fie…
Is there a left-handed magnetic field in the solar neighborhood? Exploring helical magnetic fields in the interstellar medium through dust polarization power spectra
Andrea Bracco, Simon Candelaresi, Fabio Del Sordo +1
The full-sky Planck polarization data at 850um revealed unexpected properties of the E and B mode power spectra of dust emission in the interstellar medium (ISM). The positive cros…
Estimating the rate of field line braiding in the solar corona by photospheric flows
Simon Candelaresi, David Pontin, Anthony Yeates +2
In this paper we seek to understand the timescale on which the photospheric motions on the Sun braid coronal magnetic field lines. This is a crucial ingredient for determining the…
Calculations for the Practical Applications of Quadratic Helicity in MHD
Petr M. Akhmet'ev, Simon Candelaresi, Alexandr Yu Smirnov
For the quadratic helicity we present a generalization of the Arnol'd inequality which relates the magnetic energy to the quadratic helicity, which poses a lower bound. W…
Small-scale magnetic helicity losses from a mean-field dynamo
Axel Brandenburg, Simon Candelaresi, Piyali Chatterjee
Using mean-field models with a dynamical quenching formalism we show that in finite domains magnetic helicity fluxes associated with small-scale magnetic fields are able to allevia…
