Observations of occultations of bright -ray sources by the Sun may reveal predicted pair halos around blazars andor new physics, such as, e.g., hypothetical light dark matter particles-axions. We use () data to analyze four occultations of blazar 3C 279 by the Sun on October 8 each year from 2008 to 2011. A combined analysis of the observations of these occultations allows a point-like source at the position of 3C 279 to be detected with significance of ≈3, but does not reveal any significant excess over the flux expected from the quiescent Sun. The likelihood ratio test rules out complete transparency of the Sun to the blazar -ray emission at a 3 confidence level.
对太阳遮挡明亮射线源的观测可能会揭示耀变体周围预测的双晕以及/或者新物理现象，例如假设的轻暗物质粒子——轴子。我们利用（）数据来分析2008年至2011年每年10月8日太阳对耀变体3C 279的四次掩星情况。对这些掩星观测结果的综合分析使得能在3C 279位置探测到一个点状源，显著性约为3，但未发现相对于静止太阳预期通量有任何显著过量。似然比检验在3置信水平下排除了太阳对耀变体射线发射完全透明的情况。
