论文摘要
我们基于从高海拔水分Cherenkov(HAWC)天文台的6。1年的数据基于6。1年的数据,该数据首次从太阳能磁盘(6.3 $σ$)报告了TEV Gamma-ray通量。 0.5--2.6 TEV频谱非常适合Power Law,DN/DE = $ a(E/1 \ text {tev})^{ - γ} $,$ a =(1.6 \ pm 0.3)\ times 10^{ - 12} { - 12} $ tev $ tev $ tev $^{ - 1} $ cm $ cm $ cm $ cm $ cm $^$^ - 2} $^ - 2} $^{ - 2} $^{ - 2} $^{ - 2} $^{ - } $^{ - 2} $^{ - 1} - 和2} - 2 \ pm 0.14 $。通量显示出与太阳活性的强大相关指示。这些结果扩大了从Fermi-Lat观察到的磁盘的明亮,硬GEV发射,似乎是由于太阳大气中的核对核上淋浴的黑室银河宇宙射线造成的。但是,当前的理论模型无法解释太阳磁场如何塑造这些相互作用的细节。因此,HAWC的TEV检测加深了太阳能发射的奥秘。
We report the first detection of a TeV gamma-ray flux from the solar disk (6.3$σ$), based on 6.1 years of data from the High Altitude Water Cherenkov (HAWC) observatory. The 0.5--2.6 TeV spectrum is well fit by a power law, dN/dE = $A (E/1 \text{ TeV})^{-γ}$, with $A = (1.6 \pm 0.3) \times 10^{-12}$ TeV$^{-1}$ cm$^{-2}$ s$^{-1}$ and $γ= -3.62 \pm 0.14$. The flux shows a strong indication of anticorrelation with solar activity. These results extend the bright, hard GeV emission from the disk observed with Fermi-LAT, seemingly due to hadronic Galactic cosmic rays showering on nuclei in the solar atmosphere. However, current theoretical models are unable to explain the details of how solar magnetic fields shape these interactions. HAWC's TeV detection thus deepens the mysteries of the solar-disk emission.
