Heating of Magnetically Dominated Plasma by Alfvén-Wave Turbulence
J. Nättilä, A. M. Beloborodov
Magnetic energy around astrophysical compact objects can strongly dominate over plasma rest mass. Emission observed from these systems may be fed by dissipation of Alfvén wave turb…
New applications for the Boris Spectral Deferred Correction algorithm for plasma simulations
Kris Smedt, Daniel Ruprecht, Jitse Niesen +2
The paper investigates two new use cases for the Boris Spectral Deferred Corrections (Boris-SDC) time integrator for plasma simulations. First, we show that using Boris-SDC as a pa…
Segmentation of turbulent computational fluid dynamics simulations with unsupervised ensemble learning
Maarja Bussov, Joonas Nättilä
Computer vision and machine learning tools offer an exciting new way for automatically analyzing and categorizing information from complex computer simulations. Here we design an e…
Coherent Electromagnetic Emission from Relativistic Magnetized Shocks
Lorenzo Sironi, Illya Plotnikov, Joonas Nättilä +1
Relativistic magnetized shocks are a natural source of coherent emission, offering a plausible radiative mechanism for Fast Radio Bursts (FRBs). We present first-principles 3D simu…
Multimessenger constraints for ultra-dense matter
Eemeli Annala, Tyler Gorda, Evangelia Katerini +4
Recent rapid progress in neutron-star (NS) observations offers great potential to constrain the properties of strongly interacting matter under the most extreme conditions. In orde…
