The magnetic breakout model, in which reconnection in the corona leads to destabilization of a filament channel, explains numerous features of eruptive solar events, from small-scale jets to global-scale coronal mass ejections (CMEs). The underlying... Read More about From Pseudostreamer Jets to Coronal Mass Ejections: Observations of the Breakout Continuum.

Wave-averaged balance: a simple example (2021)
Journal Article
Kafiabad, H. A., Vanneste, J., & Young, W. R. (2021). Wave-averaged balance: a simple example. Journal of Fluid Mechanics, 911, Article R1. https://doi.org/10.1017/jfm.2020.1032

In the presence of inertia-gravity waves, the geostrophic and hydrostatic balance that characterises the slow dynamics of rapidly rotating, strongly stratified flows holds in a time-averaged sense and applies to the Lagrangian-mean velocity and buoya...

(Mis-)matching type-B anomalies on the Higgs branch (2021)
Journal Article
Niarchos, V., Papageorgakis, C., Pini, A., & Pomoni, E. (2021). (Mis-)matching type-B anomalies on the Higgs branch. Journal of High Energy Physics, 2021, Article 106. https://doi.org/10.1007/jhep01%282021%29106

Building on [1], we uncover new properties of type-B conformal anomalies for Coulomb-branch operators in continuous families of 4D N = 2 SCFTs. We study a large class of such anomalies on the Higgs branch, where conformal symmetry is spontaneously br... Read More about (Mis-)matching type-B anomalies on the Higgs branch.

Plumelets: Dynamic Filamentary Structures in Solar Coronal Plumes (2021)
Journal Article
Uritsky, V., DeForest, C., Karpen, J., DeVore, C., Kumar, P., Raouafi, N., & Wyper, P. (2021). Plumelets: Dynamic Filamentary Structures in Solar Coronal Plumes. Astrophysical Journal, 907(1), https://doi.org/10.3847/1538-4357/abd186

Solar coronal plumes long seemed to possess a simple geometry supporting spatially coherent, stable outflow without significant fine structure. Recent high-resolution observations have challenged this picture by revealing numerous transient, small-sc... Read More about Plumelets: Dynamic Filamentary Structures in Solar Coronal Plumes.

Instability thresholds for thermal convection in a Kelvin–Voigt fluid of variable order (2021)

We present numerical techniques for calculating instability thresholds in a model for thermal convection in a complex viscoelastic fluid of Kelvin–Voigt type. The theory presented is valid for various orders of an exponential fading memory term, and... Read More about Instability thresholds for thermal convection in a Kelvin–Voigt fluid of variable order.

We introduce the Writhe Application Software Package (WASP) which can be used to characterisze the topology of ribbon structures, the underlying mathematical model of DNA, Biopolymers, superfluid vorticies, elastic ropes and magnetic flux ropes. This... Read More about WASP: a software package for correctly characterizing the topological development of ribbon structures.

Resurgent expansion of Lambert series and iterated Eisenstein integrals (2021)
Journal Article

We consider special Lambert series as generating functions of divisor sums and determine their complete transseries expansion near rational roots of unity. Our methods also yield new insights into the Laurent expansions and modularity properties of i... Read More about Resurgent expansion of Lambert series and iterated Eisenstein integrals.
