论文摘要
我们用核光谱望远镜阵列（NUSTAR）进行了光谱分析，该示波器阵列（Nustar）具有四个分离的星系，该星系具有活性银河系核，从2MIG目录中选择：NGC 5347，ESO 438-009，MCG-02-09-09-040，以及IGR J11366-6002。我们还使用Swift/爆发警报望远镜（BAT）数据最高$ \ sim $ 150 KEV，用于MCG 02-09-040，ESO 438-009和IGR J11366-6002，以及NGC 5347，ESO 4388-338-009，J11的0.3---10 KeV Energe ins in 0.3----10 KeV Energe ins的Swift/XRT数据。除了主要的幂律连续体外，所有来源似乎都具有不同反射部分的反射频谱分量。我们发现这些来源的幂律指数位于1.6至1.8之间。 NGC 5347和MCG-02-09-040的两个来源的光谱显示了Fe $K_α$发射线。对于这两个来源，fe $k_α$线都具有巨大的ew $ \ sim $ 1 kev。 NGC 5347的X射线频谱是使用$ e_ {cut} \ sim 117 $ keV的纯反射模型最好拟合的，并且没有任何其他主要的幂律组件。我们还发现，MCG -02-09-040的X射线频谱显示出$ N_ {H} \ SIM10^{24} 〜CM^{ - 2} $的沉重中性模糊。但是，在情况下，这提供了反射的非物理值，并通过简单的反射模型拟合。采用基于蒙特卡洛的模型作为bntorus获得了更合适的拟合。它允许我们确定n $ _ {h} \ sim1.04 \ times10^{24} 〜cm^{ - 2} $的吸收值和$γ\的合理幂律索引约1.63 $。首次提出MCG -02-09-040的结果。
We present the spectral analysis with the Nuclear Spectroscopic Telescope Array (NuSTAR) of four isolated galaxies with active galactic nuclei selected from 2MIG catalogue: NGC 5347, ESO 438-009, MCG-02-09-040, and IGR J11366-6002. We also used the Swift/Burst Alert Telescope (BAT) data up to $\sim$ 150 keV for MCG 02-09-040, ESO 438-009, and IGR J11366-6002 as well as the Swift/XRT data in 0.3--10 keV energy band for NGC 5347, ESO 438-009, and IGR J11366-6002. All the sources appear to have the reflected spectrum component with different reflection fractions in addition to the primary power-law continuum. We found that power-law indices for these sources lie between 1.6 to 1.8. The spectra of two sources, NGC 5347 and MCG-02-09-040, show the Fe $K_α$ emission line. For both of these sources, the Fe $K_α$ lines have a large value of EW $\sim$ 1 keV. The X-ray spectrum of NGC 5347 is being best fitted by a pure reflection model with $E_{cut} \sim 117$ keV and without the presence of any additional primary power-law component. We also found that X-ray spectrum of MCG -02-09-040 shows the presence of heavy neutral obscuration of $N_{H}\sim10^{24}~cm^{-2}$. However, this provides a non-physical value of reflection in the case with fitting by a simple reflection model. A more appropriate fit is obtained with adopting the physical Monte Carlo based model as BNTorus. It allowed us to determine the absorption value of N$_{H}\sim1.04\times10^{24}~cm^{-2}$ and reasonable power-law index of $Γ\approx 1.63$. Results for MCG -02-09-040 are presented for the first time.
