A search for chaos in the blazar: W2R 1926+42 and its possible consequence |
|
Abstract |
By using publicly available data, we search for signatures of low-dimensional chaos in the temporal behavior of the Kepler-field blazar W2R 1946+42. We use an ~160000 points long and mostly equally spaced light curve and apply the correlation integral method to both -- real datasets and phase randomized "surrogates". However, we are not able to confirm the presence of low-dimensional chaos in the light curve. Although not entirely conclusive, these results may suggest for the mechanism of particle acceleration. Models, based on a ”single engine”, operating perhaps close to the jet base seem unlikely. Models, relying on the presence of many independent active zones, like multiple magnetic reconnections or turbulence within the jet, are more plausible. |
