论文摘要
我们提出了一种自谐的方式,它在伽马射线爆发余潮中建模同步体自我compton(SSC)效应,有和没有近似的klein-nishina抑制散射。我们提供了结果的分析近似,以便可以将其合并到余辉建模代码\ texttt {boxfit}中,该{BoxFit}目前基于纯同步子发射。我们讨论了由于SSC效应而引起的光谱形状和演变的变化,并评论这些变化如何影响宽带建模的物理参数。我们表明,使用包括这些效果在内的模拟,SSC效应可以对X射线光曲线的形状产生深远的影响。这会导致数据在考虑仅同步加速器拟合时不能同时拟合的X射线和无线电频段,并且无法恢复正确的物理参数,而某些拟合参数则与模拟的输入参数偏离数量级。这可能会根据以前的宽带建模工作对物理参数分布产生重大影响。
We present a self-consistent way of modeling synchrotron self-Compton (SSC) effects in gamma-ray burst afterglows, with and without approximated Klein-Nishina suppressed scattering. We provide an analytic approximation of our results, so that it can be incorporated into the afterglow modeling code \texttt{boxfit}, which is currently based on pure synchrotron emission. We discuss the changes in spectral shape and evolution due to SSC effects, and comment on how these changes affect physical parameters derived from broadband modeling. We show that SSC effects can have a profound impact on the shape of the X-ray light curve using simulations including these effects. This leads to data that cannot be simultaneously fit well in both the X-ray and radio bands when considering synchrotron-only fits, and an inability to recover the correct physical parameters, with some fitted parameters deviating orders of magnitude from the simulated input parameters. This may have a significant impact on the physical parameter distributions based on previous broadband modeling efforts.
