脉冲星风云3C58的非热多波段辐射与动力学演化特性

Nonthermal multiband radiation and dynamical evolution properties of the pulsar wind nebula 3C58

脉冲星风云3C58是由脉冲星PSR J0205+6499驱动的星云,具有明显的非热多波段辐射特征.基于包含星云动力学过程的谱演化模型,拟合了该脉冲星风云的多波段非热辐射谱,探究了其多波段能谱随时间的演化特征.模型结果表明,脉冲星风云3C58的多波段辐射流量随时间具有明显的演化特征.

Pulsar wind nebula(pwn)3C58 is powered by the center pulsar PSR J0205+6449,which can emit multiband nonthermal photons ranging from radio to TeV gamma-ray bands.The nonthermal multiband radiation of the pwn is reconstructed by using the spectral evolution model,and then the temporal evolution of the multiband spectra of the nebula is investigated.The modeling results reveal significant differences in the nonthermal spectra of 3C58 as the time increases.
