On the cool nature of coronal nanojets
Gabriele Cozzo, Paola Testa, Juan Martinez-Sykora +5
Reconnection-driven nanoflares are widely considered a leading mechanism for coronal-loop heating, but their direct fingerprints in the tenuous coronal plasma remain elusive. The r…

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…
