Magnetic winding: what is it and what is it good for?
Chris Prior, David MacTaggart
Magnetic winding is a fundamental topological quantity that underpins magnetic helicity and measures the entanglement of magnetic field lines. Like magnetic helicity, magnetic wind…
Field line winding of braided vector fields in tubular subdomains
Christopher B Prior, Anthony R Yeates
Braided vector fields on spatial subdomains homeomorphic to the cylinder play a crucial role in applications such as solar and plasma physics, relativistic astrophysics, fluid and…
Spatial Scales and Locality of Magnetic Helicity: Part 1
Christopher Prior, Gareth Hawkes, Mitch Berger
Magnetic helicity is approximately conserved in resistive MHD models. It quantifies the entanglement of the magnetic field within the plasma. The transport and removal of helicity…
Helicity and winding fluxes as indicators of twisted flux emergence
David MacTaggart, Chris Prior
Evidence for the emergence of twisted flux tubes into the solar atmosphere has, so far, come from indirect signatures. In this work, we investigate the topological input of twisted…
Observational signatures of magnetic field structure in relativistic AGN jets
Christopher Prior, Konstantinos N. Gourgouliatos
Context. Active Galactic Nuclei (AGN) launch highly energetic jets sometimes outshining their host galaxy. These jets are collimated outflows that have been accelerated near a supe…
On the Helicity of Open Magnetic Fields
C. Prior, A. R. Yeates
We reconsider the topological interpretation of magnetic helicity for magnetic fields in open domains, and relate this to the relative helicity. Specifically, our domains stretch b…
