论文摘要
假定宇宙中缺少的重子被认为是一种暖热的播种培养基（WHIM）。找到它们是现代宇宙学的重要主题之一。在本文中，我们指出，根据改进的伯特·赫特勒公式，由于异常的bremsstrahlung，高能电子/正电子射线可能会点亮偶然的。可以通过直接测量方法观察到产生的过量背景光（EBL）。还提出了关于EBL直接测量和间接测量之间差异的可能解释。因此，我们找到了一个新窗口，可以通过EBL探测异想天开的属性。
The missing baryons in the universe are assumed to be hidden in the whole space as a warm-hot intergalactic medium (WHIM). Finding them is one of the important subjects in modern cosmology. In this paper, we point out that the very high energy electron/positron rays may light up the WHIM due to the anomalous bremsstrahlung according to an improved Bethe-Heitler formula. The resulting excess of the extragalactic background light (EBL) can be observed by the direct measurement method. A possible explanation on the difference between the direct and indirect measurements of EBL is also proposed. Thus, we find a new window to probe the WHIM properties via the EBL.
