我们提出了一个随时间变化的星云3C 58的光谱模型，并与现有的数据进行比较。该模型是一个轻子星云中的粒子受到同步加速器，逆康普顿，自同步康普顿，绝热和韧致辐射过程。我们发现3C 58是一个粒子主导的星云，磁场为35 μG。破幂律注入与多频数据非常吻合，破幂能量约为40 GeV。我们发现3C 58不会出现在VERITAS或MAGIC II中，除非当地的红外背景是银河系模型平均值的20倍。对于宇宙微波背景辐射占主导地位的逆康普顿贡献的情况下，我们发现，3C 58将是不可见的切伦科夫望远镜阵列。
We present a time-dependent spectral model of the nebula 3C 58 and compare it with available data. The model is for a leptonic nebula in which particles are subject to synchrotron, inverse Compton, self-synchrotron Compton, adiabatic, and bremsstrahlung processes. We find that 3C 58 is compatible with being a particle-dominated nebula, with a magnetic field of 35 μG. A broken power-law injection fits well the multi-frequency data, with a break energy at about 40 GeV. We find that 3C 58 is not expected to appear in VERITAS or MAGIC II, unless the local IR background is a factor of ∼20 off Galactic models' averages. For cases in which the cosmic microwave background dominates the inverse Compton contribution, we find that 3C 58 will not be visible either for the Cherenkov Telescope Array.
