» On the intrinsic simplicity of spectral variability of GRBs

Presentation duration: 20 minutes

Presenter: Anton Chernenko

Relativistically expanding sources produce radiation that manifest rich spectral evolution and diverse light curve structures. Even if individual emitting regions have similar and simple geometry and rest frame spectra, spectral and temporal evolution within any period of observer's time would be very diverse, since many of individual emitters would contribute to this period at different viewing angles, Lorentz factors and at different stages of development. In this paper I present multi-scale correlation analysis of light curves recorded in different energy ranges, which allows one to determine number of emitters and recover simple spectral properties of each emitter.
