3D MHD simulations of coronal loops heated via magnetic braiding I. Continuous driving
Gabriele Cozzo, Paola Testa, Juan Martinez-Sykora +13
The nature and detailed properties of the heating of the million-degree solar corona are important issues that are still largely unresolved. Nanoflare heating might be dominant in…

The X-ray Integral Field Unit at the end of the Athena reformulation phase
Philippe Peille, Didier Barret, Edoardo Cucchetti +279
The Athena mission entered a redefinition phase in July 2022, driven by the imperative to reduce the mission cost at completion for the European Space Agency below an acceptable ta…

Coronal energy release by MHD avalanches II. EUV line emission from a multi-threaded coronal loop
G. Cozzo, J. Reid, P. Pagano +13
MHD kink instability can trigger the fragmentation of a twisted magnetic flux tube into small-scale current sheets that dissipate as aperiodic impulsive heating events. This instab…
