The Energy-Duration Relationship in Astrophysical Self-Organized Criticality Systems
Markus J. Aschwanden, Alexandre Araujo
Scaling laws in astrophysical systems that involve the energy, the geometry, and the spatio-temporal evolution, provide the theoretical framework for physical models of energy diss…
New Trends in Astrophysical Self-Organized Criticality
Markus J. Aschwanden
This review is focused on recent {\sl Self-Organized Criticality (SOC)} literature of astrophysical phenomena, covering the last decade of (2015-2025), while previous SOC literatur…
Power Laws Associated with Self-Organized Criticality: A Comparison of Empirical Data with Model Predictions
Markus J. Aschwanden, Felix Scholkmann
We investigate the relevance of {\sl self-organized criticality (SOC)} models in previously published empirical datasets, which includes statistical observations in astrophysics, g…
Self-Organized Criticality Across Thirteen Orders of Magnitude in the Solar-Stellar Connection
Markus J. Aschwanden, Carolus, J. Schrijver
The observed size distributions of solar and stellar flares is found to be consistent with the predictions of the fractal-diffusive self-organized criticality (FD-SOC) model, which…
Universal Constants and Energy Integral in Self-Organized Criticality Systems
Markus Aschwanden
The occurrence frequency distributions of fluxes (F) and fluences or energies (E) observed in astrophysical observations are found to be consistent with the predictions of the frac…
Testing the Universality of Self-Organized Criticality in Galactic, Extra-Galactic, and Black-Hole Systems
Markus Aschwanden, Ersin Gogus
In this study we are testing whether the power law slopes (, ) of fluxes , fluences or energies are universal in their size distributions, $N(F) \propto F^{-…
