论文摘要
我们较早提出的暗物质模型，由CM大小的珍珠组成，在高压下具有普通物质，并以$ 1.4 *10^8 $ kg的订单组成，用于解释来自银河系中心的神秘3.5 kev X射线线以及各种星系和星系簇。珍珠是一种新型真空的气泡，因此被提供高压的表面张力所包围。 我们有两个相当成功的数值结果： 1）3.5 keV的X射线能量是作为同余隙的3.5 keV，或者是由于珍珠内高压普通物质中电子筛选而引起的能量，并且非常合适。 ％在因子％{\ bf tbc 2}％3中正确预测的％; ％$ 40 \％$; 2）使用Cline和Frey拟合，用于碰撞或暗物质颗粒的歼灭产生的暗物质辐射，我们适合珍珠模型中辐射的总体强度。 我们发现，正如我们先前的工作\ cite {tunguska}所使用的稳定性所需的最小尺寸的珍珠与观察到的3.5 keV线的频率和强度不一致。但是，我们模型的预测对珍珠半径非常敏感，并且对于半径为2.8 cm的珍珠获得了两种实验量的极好拟合。
Our earlier put forward model of dark matter, consisting of cm-size pearls with ordinary matter inside under high pressure and with a mass of order $1.4 *10^8$ kg, is used to explain the mysterious 3.5 keV X-ray line from the galactic center and various galaxies and galaxy clusters. The pearls are bubbles of a new type of vacuum and thus surrounded by a surface tension providing the high pressure. We have two rather successful order of magnitude numerical results: 1) the X-ray energy of 3.5 keV comes out as the homolumo-gap or rather as the energy due to screening of electrons in the high pressure ordinary matter inside the pearls, and is well fitted. %predicted correctly to within a factor %{\bf tbc 2} %3; %$40 \%$; 2) Using the fitting of Cline and Frey for dark matter radiation arising from collisions or annihilations of dark matter particles we fit the overall intensity of the radiation in our pearl model. We find that a pearl of the minimal size required just by stability, as used in our previous work \cite{Tunguska}, is inconsistent with the observed frequency and intensity of the 3.5 keV line. However the predictions of our model are very sensitive to the radius of the pearls and an excellent fit to both experimental quantities is obtained for a pearl of radius of 2.8 cm.
