Power laws and distributions with heavy tails are common features of many complex
systems. Examples are the distribution of earthquake magnitudes, solar flare intensities and …

Shortly after the seminal paper “Self-Organized Criticality: An explanation of 1/f noise” by
Bak et al.(1987), the idea has been applied to solar physics, in “Avalanches and the …

Inhomogeneous temporal processes, like those appearing in human communications,
neuron spike trains and seismic signals, consist of high-activity bursty intervals alternating …

Bursty dynamics is a common temporal property of various complex systems in nature but it
also characterises the dynamics of human actions and interactions. At the …

The statistics of quiescent times τ L between successive bursts of solar flares activity,
performed using 20 years of data, displays a power law distribution with exponent α≃ 2.4 …

It was recently pointed out that the distribution of times between solar flares (the flare waiting-
time distribution) follows a power law for long waiting times. Based on 25 years of soft X-ray …

We study the statistics of soft gamma repeater (SGR) bursts using a database of 187 events
detected with BATSE and 837 events detected with the Rossi X-Ray Timing Explorer …

This paper is a pedagogical introduction to avalanche models of solar flares, including a
comprehensive review of recent modeling efforts and directions. This class of flare model is …

This review surveys the statistics of solar X-ray flares, emphasising the new views that
RHESSI has given us of the weaker events (the microflares). The new data reveal that these …

Non-Poissonian bursty processes are ubiquitous in natural and social phenomena, yet little
is known about their effects on the large-scale spreading dynamics. In order to characterize …
