论文摘要
我们介绍了X射线光谱的结果和最接近的伽马射线发射窄线Seyfert 1（$γ$ -NLS1）Galaxy，1H 0323+342的结果。我们使用了最近的同时XMM-Newton/Nustar活动中的观察结果。与Radio-Quiet NLS1中一样，频谱在低能（$ \ lyssim2 $ keV）和反射特征（例如宽铁K发射线）中揭示了柔软的多余。我们还发现证据表明，超过$ \ sim35 $ keV的能量艰难，这可能是喷射排放的结果。我们的分析表明，相对论反射是统计上需要的，并且使用包括宽带光谱的反射模型relxill的组合，我们发现$ i = 63^{+7} _ { - 5} $程度的倾斜度在无线电观察中所推断的值较低，其值较低。我们还发现平坦（$ q = 2.2 \ pm0.3 $）发射率概况，这意味着比磁盘外部区域发出的反射助剂更多的助焊剂反射，这反过来表明偏离了薄磁盘模型假设。我们讨论了可能的原因，例如从厚的积聚磁盘几何形状中反射。
We present the results of X-ray spectral and timing analyses of the closest gamma-ray emitting narrow-line Seyfert 1 ($γ$-NLS1) galaxy, 1H 0323+342. We use observations from a recent, simultaneous XMM-Newton/NuSTAR campaign. As in radio-quiet NLS1s, the spectrum reveals a soft excess at low energies ($\lesssim2$ keV) and reflection features such as a broad iron K emission line. We also find evidence of a hard excess at energies above $\sim35$ keV that is likely a consequence of jet emission. Our analysis shows that relativistic reflection is statistically required, and using a combination of models that includes the reflection model relxill for the broadband spectrum, we find an inclination of $i=63^{+7}_{-5}$ degrees, which is in tension with much lower values inferred by superluminal motion in radio observations. We also find a flat ($q=2.2\pm0.3$) emissivity profile, implying that there is more reflected flux than usual being emitted from the outer regions of the disk, which in turn suggests a deviation from the thin disk model assumption. We discuss possible reasons for this, such as reflection off of a thick accretion disk geometry.
