Direct detection of axions of celestial origin

我们用轴子日光镜扫描了天球，以寻找可能的轴子点源。我们还用轴子日光镜跟踪了某些天体，如银河系中心、蝎子X-1、船帆座X-1和蟹状星云，以寻找轴子。我们首次通过地面直接搜索对来自这些天体的轴子通量进行了限制，然后将AXION HELIOSCOPE对准软伽马射线中继器SGR 1900 14，以寻找在其非常强的磁场下产生的轴子。我们第一次对来自它的轴子通量进行了限制。

We scanned the celestial sphere with the axion helioscope to search for a possible point source of axions. We also tracked with the axion helioscope certain celestial objects, the galactic ceneter, the scorpion X-1, the Vela X-1 and Crab nebula, in search of the axion. We put limits on the axion flux coming from these objects for the first time by the ground-based direct search.The AXION HELIOSCOPE is then directed toward the soft gamma ray repeater SGR 1900+14 to search for axions produced in it with its very strong magnetic field. We put a limit on the axion flux coming from it for the first time.
