论文摘要
在以暗物质为主物体的光谱中检测到3.5 keV约3.5 keV的一条身份不明的线。甜点等的最新工作。 [1812.06976]使用30毫秒的XMM-Newton空白观测来限制可允许的线路通量，从而挑战了其暗物质衰减的起源。我们证明，由于背景建模不当，这些界限被超过一个数量级的数量级高估了。因此，3.5 KEV信号的暗物质解释仍然可行。
An unidentified line at energy around 3.5 keV was detected in the spectra of dark matter-dominated objects. Recent work of Dessert et al. [1812.06976] used 30 Msec of XMM-Newton blank-sky observations to constrain the admissible line flux, challenging its dark matter decay origin. We demonstrate that these bounds are overestimated by more than an order of magnitude due to improper background modeling. Therefore the dark matter interpretation of the 3.5 keV signal remains viable.
