论文摘要

在本文中,我们对暗物质(DM)和中微子之间相互作用的可能影响进行了彻底的研究。我们使用21 cm宇宙学限制了相互作用强度,并发现与标准的,非相互作用的$λ$ CDM方案可能偏离。将结果与当前宇宙学观察的现有约束进行比较表明,21 cm的观察结果更有能力以几个数量级来限制相互作用强度。我们还搜索了通过进行预测分析和误差估计,在即将到来的21 cm任务SKA1-LOW中检测任何此类相互作用的前景。

In this article, we have done a thorough investigation of the possible effects of interaction between dark matter (DM) and neutrinos on reionization history. We have constrained the interaction strength using 21 cm Cosmology and found out possible deviations from standard, non-interacting $Λ$CDM scenario. Comparing the results with the existing constraints from present cosmological observations reveals that 21 cm observations are more competent to constrain the interaction strength by a few orders of magnitude. We have also searched for prospects of detecting any such interaction in the upcoming 21 cm mission SKA1-Low by doing a forecast analysis and error estimation.
