Kompaneets方程的相对论修正
Relativistic corrections to the Kompaneets equation
摘要：
我们研究星系团的Sunyaev-Zeldovich效应。我们探讨了Kompaneets方程在两种不同的展开近似方案，即Fokker-Planck展开近似和δ函数展开近似下的相对论修正。我们表明，两个膨胀近似形式主义是等价的汤姆逊近似下，这是非常好的近似的CMB光子能量。这将澄清现有的理论方法来分析观测数据的情况。
英文摘要：
We study the Sunyaev-Zeldovich effect for clusters of galaxies. We explore the relativistic corrections to the Kompaneets equation in terms of two different expansion approximation schemes, namely, the Fokker-Planck expansion approximation and delta function expansion approximation. We show that two expansion approximation formalisms are equivalent under the Thomson approximation, which is extremely good approximation for the CMB photon energies. This will clarify the situation for existing theoretical methods to analyse observation data.
