论文摘要
我们已经通过新的光谱观察结果研究了星系对IRAS 05589+2828和2MasX J06021107+2828382中先前检测到的双AGN系统的核区域，以及无线电和X射线档案数据。 Our multiwavelength data strongly suggest that the Sy1 \iras\, (z=0.0330$\pm$0.0002) conforms to a dual AGN system with the Sy2 \twomas\, (z=0.0334$\pm$0.0001) with a projected separation obtained from the radio data of 20.08\arcsec\, （$ \ sim $ 13.3 \，kpc）。对光谱的分析表明，在两个AGN中，H $α$和[OIII]的狭窄狭窄延长发射，支持了正在进行的合并的证据。 \ iras \是一个双组件窄发射线AGN，具有复杂的宽Balmer发射线轮廓，显然显示出强烈的红色峰，速度转移$ \ sim $ 3500 \，km \，s $^{ - 1} $。 \ iras \和\ twomas \的黑洞质量估计值是log \，m $ \ rm_ {bh} $ \，= \，8.59 \，$ \ pm $ \，0.14（m $ _ \ odot $）和log \ f \ \，m $ $ \，$ \ $ \ $ \ \ \ \ \ 0.2 （M $ _ \ odot $）。在X射线频段中，\ iras \与类型1对象兼容，既显示光谱变化又显示。 \ chandra \，2Masx \，J06021107+2828382的数据使我们能够测量该来源的高硬度比，从而提供了2型AGN的证据。用{\ it Karl G.

We have studied the nuclear region of the previously detected dual AGN system in the galaxy pair IRAS 05589+2828 and 2MASX J06021107+2828382 through new optical spectroscopy observations, along with radio and X-ray archival data. Our multiwavelength data strongly suggest that the Sy1 \iras\, (z=0.0330$\pm$0.0002) conforms to a dual AGN system with the Sy2 \twomas\, (z=0.0334$\pm$0.0001) with a projected separation obtained from the radio data of 20.08\arcsec\, ($\sim$13.3\,kpc). Analysis of the optical spectra reveals a faint narrow extended emission from H$α$ and [OIII] amidst the two AGN, supporting evidence for an ongoing merger. \iras\, is a double component narrow emission line AGN, with complex broad Balmer emission line profiles that clearly show a strong red-peaklet with a velocity shift of $\sim$3500\,km\,s$^{-1}$. The black hole mass estimates of \iras\, and \twomas\, are log\,M$\rm_{BH}$\,=\,8.59\,$\pm$\,0.14 (M$_\odot$) and log\,M$\rm_{BH}$\,=\,8.21$\pm$0.2 (M$_\odot$), respectively. In the X-ray bands, \iras\, is compatible with a Type 1 object, showing both spectral and flux variability. \chandra\, data of 2MASX\,J06021107+2828382 allowed us to measure a high hardness ratio in this source, providing evidence for a Type 2 AGN. The 22 GHz image obtained with the {\it Karl G. Jansky Very Large Array} has revealed that both AGN are compact radio objects with spectral indices -0.26$\pm$0.03 and -0.70$\pm$0.11, confirming for the first time its dual AGN nature in the radio bands.
