AI 中文摘要
我们利用费米伽马射线空间望远镜上大面积望远镜（LAT）收集的数据，并考虑LAT 16年源列表（FL16Y），报告了射电宁静窄线赛弗特1星系1H 1934-063的伽马射线过剩情况。在耀斑期间，在1-500 GeV波段以约5.2σ（TS = 27.12）的显著性检测到过剩，光子通量为(4.94±2.33)×10⁻¹⁰ ph cm⁻² s⁻¹，硬光子指数Γ = 1.50±0.25。最佳拟合伽马射线位置与1H 1934-063的射电位置一致，而附近源FL16Y J1936.9-0552在此期间未被显著检测到。由于缺乏同期多波长数据，宽带解释受到限制。紧凑的非热成分可产生硬GeV发射，但目前数据无法进行唯一物理解释。尽管潜在物理机制仍不确定，但该过剩为探测射电宁静NLS1星系的高能活动提供了有趣案例。
英文摘要
We report a $γ$-ray excess toward the radio-quiet narrow-line Seyfert 1 galaxy 1H 1934-063 using data collected by the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope and taking into account the LAT 16-year Source List (FL16Y). During the flare interval, the excess is detected in the 1--500 GeV band at a significance of $\sim 5.2σ$ (TS = 27.12), with a photon flux of $(4.94\pm2.33)\times10^{-10}$ ph cm$^{-2}$ s$^{-1}$ and a hard photon index of $Γ=1.50\pm0.25$. The best-fit $γ$-ray position is consistent with the radio position of 1H 1934-063, while the nearby source FL16Y J1936.9-0552 is not significantly detected during the same interval. In the absence of contemporaneous multiwavelength data, the broadband interpretation cannot be tightly constrained. A compact nonthermal component can produce the hard GeV emission, but the present data do not allow a unique physical interpretation. The excess therefore provides an interesting case for probing high-energy activity in radio-quiet NLS1 galaxies, although the underlying physical mechanism remains uncertain.
