Small-scale magnetic reconnection processes , in the form of nanoflares , have become increasingly hypothesized as important mechanisms for the heating of the solar atmosphere , for driving propagating disturbances along magnetic field lines in the Sun ’ s corona , and for instigating rapid jet-like bursts in the chromosphere .
Unfortunately , the relatively weak signatures associated with nanoflares places them below the sensitivities of current observational instrumentation .
Here , we employ Monte Carlo techniques to synthesize realistic nanoflare intensity time series from a dense grid of power-law indices and decay timescales .
Employing statistical techniques , which examine the modeled intensity fluctuations with more than 10 ^ { 7 } discrete measurements , we show how it is possible to extract and quantify nanoflare characteristics throughout the solar atmosphere , even in the presence of significant photon noise .
A comparison between the statistical parameters ( derived through examination of the associated intensity fluctuation histograms ) extracted from the Monte Carlo simulations and SDO/AIA 171 Å and 94 Å observations of active region NOAA 11366 reveals evidence for a flaring power-law index within the range of 1.82 \leq \alpha \leq 1.90 , combined with e -folding timescales of 385 \pm 26 s and 262 \pm 17 s for the SDO/AIA 171 Å and 94 Å channels , respectively .
These results suggest that nanoflare activity is not the dominant heating source for the active region under investigation .
This opens the door for future dedicated observational campaigns to not only unequivocally search for the presence of small-scale reconnection in solar and stellar environments , but also quantify key characteristics related to such nanoflare activity .
