SNR CTB87 14.7GHz and 17.3GHz total intensity maps

Breaks in the radio spectra of supernova remnants (SNRs) reflect the maximum energy of either shock-accelerated electrons or - in the case of pulsar wind nebulae - of electrons...超新星遗迹（supernova remnants, SNRs）的射电频谱断裂，可反映两类情况：其一为激波加速电子的最高能量；其二在脉冲星风云（pulsar wind nebulae）的情形下，则为电子的……
