Knowledge from the time series of quasar radio‐wave flux density

Abstract

SUMMARYTime series of radio waves attributable to synchrotron radiation from quasars, that is, extragalactic systems at cosmological distances, were analyzed in an attempt to find an informational structure expressing the evolution and self-organization of the quasar system. The methods we used were power law analysis of the time series and phase space map analysis of the reconstructed time series.From the power law analysis we found that the dynamical structure of the system is likely to have evolved over the cosmic time scale. From the reconstructed phase space map analysis we obtained patterns similar to attractors in three-dimensional phase space, which may reflect the system's dynamical structure, and by applying the GP algorithm with the correlation integral we inferred that the dynamical system is of system dimension.
