论文摘要
我们提出了$ z \ sim 2.5 $镜头2mass 2mass J1042+1641的新宽带X射线观察，结合了$ xmm $ - $ xmm $ - $ newton $，$ chandra $和$ chandra $和$ nustar $，以覆盖0.3 $ $ $ $ $ $ $ $ $ $ $ $ $ $ 14的X射线频谱的报道， 2MASS J1042+1641。 The X-ray data show clear evidence for strong (but still Compton-thin) X-ray absorption, $N_{\rm{H}} \sim 3-4 \times 10^{23}$ cm$^{-2}$, in addition to significant reprocessing by Compton-thick material that must lie away from our line-of-sight to the central X-ray source.我们对后者测试了两种不同的解释：首先，重新处理发生在经典的AGN圆环中，正如统一模型中所调用的那样，其次是重新处理发生在积聚盘中。这两种模型都可以成功地重现观测到的光谱，并且都暗示，尽管吸收了沉重的吸收线，但仍以中等低的倾向（$ i <50^{\ circ} $）观看来源。将X射线数据与来自$ Wise $的红外数据相结合，从2MASS J1042+1641中看到的结果进一步支持了最近的建议，即大型X射线和IR调查可能会共同能够在详细的成像研究之前识别出良好的镜头类星体候选者。
We present new broadband X-ray observations of the $z \sim 2.5$ lensed quasar 2MASS J1042+1641, combining $XMM$-$Newton$, $Chandra$ and $NuSTAR$ to provide coverage of the X-ray spectrum over the 0.3$-$40 keV bandpass in the observed frame, corresponding to the $\sim$1$-$140 keV band in the rest-frame of 2MASS J1042+1641. The X-ray data show clear evidence for strong (but still Compton-thin) X-ray absorption, $N_{\rm{H}} \sim 3-4 \times 10^{23}$ cm$^{-2}$, in addition to significant reprocessing by Compton-thick material that must lie away from our line-of-sight to the central X-ray source. We test two different interpretations for the latter: first that the reprocessing occurs in a classic AGN torus, as invoked in unification models, and second that the reprocessing occurs in the accretion disc. Both models can successfully reproduce the observed spectra, and both imply that the source is viewed at moderately low inclinations ($i < 50^{\circ}$) despite the heavy line-of-sight absorption. Combining the X-ray data with infrared data from $WISE$, the results seen from 2MASS J1042+1641 further support the recent suggestion that large X-ray and IR surveys may together be able to identify good lensed quasar candidates in advance of detailed imaging studies.
