Description

The complex dynamics of x-ray astrophysical sources is investigated by analyzing their daily light curves in four different energy bands by using three information-theoretic measures: Fisher information measure, the Shannon entropy and the disequilibrium. The obtained results suggest a universal complex behavior in the x-ray light, independent of the source and of the energy band
