论文摘要

本文报告了$γ$ ray的2018年nova v392 v392 v392的$ \ sim $ \ sim $ 0.1 $ 0.1 GEV至100 TEV，通过结合Fermi Gamma-ray Space望远镜和HAWC天文台的观测值。在NOVA尚未观察到的最快发展的$γ$ ray信号之一中，GEV $γ$射线具有索引$γ= 2.0 \ pm 0.1 $的功率法频谱，在V392每次光学最大值之后八天内检测到了八天。 HAWC的观察结果在此期间以及之前和之后限制了TEV $γ$ ray信号。我们没有观察到TEV $γ$ ray从V392的v392，但目前的通量限制没有统计学上的显着证据。 FERMI/LAT光谱向高于5 TEV的能量的扩展的测试不受2个标准偏差（95 \％）或更多。我们将V392 PER的GEV $γ$射线与HADRONIC加速模型拟合，结合了光学观测，并将计算与HAWC限制进行了比较。

This paper reports on the $γ$-ray properties of the 2018 Galactic nova V392 Per, spanning photon energies $\sim$0.1 GeV to 100 TeV by combining observations from the Fermi Gamma-ray Space Telescope and the HAWC Observatory. In one of the most rapidly evolving $γ$-ray signals yet observed for a nova, GeV $γ$ rays with a power law spectrum with index $Γ= 2.0 \pm 0.1$ were detected over eight days following V392 Per's optical maximum. HAWC observations constrain the TeV $γ$-ray signal during this time and also before and after. We observe no statistically significant evidence of TeV $γ$-ray emission from V392 Per, but present flux limits. Tests of the extension of the Fermi/LAT spectrum to energies above 5 TeV are disfavored by 2 standard deviations (95\%) or more. We fit V392 Per's GeV $γ$ rays with hadronic acceleration models, incorporating optical observations, and compare the calculations with HAWC limits.
