Astrophysics on GPUs: introducing AGILE 1.0
Oliver Porth, Adrian Kelly, Olaf Willocx +10
We present AGILE, a GPU-enabled adaptive mesh refinement (AMR) framework for the solution of (near-) conservation laws which occur in astro- and solar-physical applications. AGILE…
Once more: Leaky MHD waves in coronal magnetic flux tubes
Hans Goedbloed, Rony Keppens
By a detailed comparison of leaky magnetohydrodynamic waves in coronal magnetic flux tubes with leaky electromagnetic waves in dielectric media it is shown that the latter kind may…
High-energy Particle Transport in Three-dimensional Anisotropic Turbulent Magnetic Fields
Daniela Maci, Rony Keppens, Fabio Bacchini
The understanding and modeling of high-energy particles transport in turbulent magnetic fields is an important open question in space- and astrophysics. The multiscale, nonlinear n…
Thermal instability in coronal loops: linking eigenvalue spectra to time-dependent evolution
Adrian Kelly, Rony Keppens, Jordi De Jonghe
Cool, dense condensations such as coronal rain and prominences suggest that coronal plasma can undergo runaway radiative cooling. Connecting this behaviour to linear thermal modes…
On the dynamics, thermodynamics and fine structure of virtual erupting filaments
Dion Donné, Yuhao Zhou, Hebe Cremades +1
It is not fully understood why some solar filaments erupt while others do not. Those that do typically undergo a slow rise followed by an acceleration phase, though this transition…
Nonthermal electron acceleration in turbulent post-flare coronal loops
Clarissa Mora, Fabio Bacchini, Rony Keppens
The generation of nonthermal electrons during solar flares plays a critical role in energy transport from the corona to the chromosphere, producing regions of observed intense X-ra…
