论文摘要
最近，有人提出，当热BREMSSTRAHLUNG发射在重组之前将其解散时，在亚GHz频率下会产生过量的Planck宇宙微波背景频谱。这本身很引人注目，这也可以解释在乳清外无线电背景的预测中长期无法解释的赤字。在此简短说明中，我们重申，当物质和辐射保持动力学耦合时，不会自行出现这种非热成分。
Recently it has been suggested that thermal bremsstrahlung emission, when it decouples prior to recombination, creates an excess over the Planck cosmic microwave background spectrum at sub-GHz frequencies. Remarkable by itself, this would also explain a long-standing unexplained deficit in the predictions of the extragalactic radio background. In this brief note we reiterate that no such non-thermal component can arise by itself when matter and radiation remain kinetically coupled.
