Chaotic Feature in the Light Curve of 3 C 273

نویسنده

  • Lei Liu
چکیده

Some nonlinear dynamical techniques, including state-space reconstruction and correlation integral, are used to analyze the light curve of 3C 273. The result is compared with a chaotic model. The similarities between them suggest that there is a low-dimensional chaotic attractor in the light curve of 3C 273.

Investigating the Chaotic Nature of Flow the Upstream and Downstream of Zayandehrud-Dam Reservoir Using Chaotic Systems’ Criteria

River discharge is among the influential factors on the operation of water resources systems and the design of hydraulic structures, such as dams; so the study of it is of great importance. Several effective factors on this non-linear phenomenon have caused the discharge to be assumed as being accidental. According to the basics the chaos theory, the seemingly random and chaotic systems have re...

Attractor Based Analysis of Centrally Cracked Plate Subjected to Chaotic Excitation

The presence of part-through cracks with limited length is one of the prevalent defects in the plate structures. Due to the slight effect of this type of damages on the frequency response of the plates, conventional vibration-based damage assessment could be a challenging task. In this study for the first time, a recently developed state-space method which is based on the chaotic excitation is ...

The blue - bump of 3 C 273

We present optical and ultraviolet observations of 3C 273 covering the whole life of the IUE satellite. We analyze the variability properties of the light curves, and find that two variable components, written B and R respectively, must contribute to the blue-bump emission in this object. The B component produces most of the variability in the ultraviolet domain. A maximum time scale of variabi...
