暗物质星系晕中的切伦科夫辐射
The Cherenkov radiation in the galaxy halo of dark matter
摘要：
考虑了由Navarro-Frenk-White和Burkett剖面描述的暗物质星系晕中光折射的影响。计算了具有这些剖面的引力场折射率的切伦科夫辐射功率。结果表明，在X射线范围内，相应的辐射温度具有微开的量级。指出它的探测可能是选择星系中较好的暗物质密度分布的依据。
英文摘要：
The effect of light refraction in a galaxy halo of dark matter, described by profiles of Navarro-Frenk-White and Burkett, was considered. Powers of the Cherenkov radiation for the refractive indexes of gravitational fields with these profiles were calculated. It was shown that correspondent radiation temperature in the X-rays range have the magnitude about some microKelvins. It was also marked that its detection may be the criteria on choosing the preferable dark matter density distribution in a galaxy.
