Revealing the most highly-accreting CT AGN in the local Universe with XMM-Newton

Heavily obscured accretion is believed to be an extremely important phase in thegrowth of supermassive black holes. However, so far only a few CT AGN are knownin the local Universe, and most of them have luminosities log(Lx) < 44.4. Wepropose here to observe the 5 most luminous CT AGN at redshift z <0.2 with nohighquality 0.310keV observation available. This will increase the sample oflocal highluminosity CT AGN by a factor of 3.5, greatly improving our knowledgeof CT obscuration at the highest accretion rates. These observations will allowto constrain the brightest end of the luminosity function of CT AGN and theevolution of the covering factor of the CT material, besides serving as abenchmark to study luminous CT AGN at higher redshifts. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]

高度遮蔽的积聚过程被认为是在超大质量黑洞成长过程中极为关键的阶段。然而，迄今为止，仅在局部宇宙中发现了少数CT AGN（连续谱活动星系核），其中大部分的亮度对数(log(Lx))小于44.4。在此，我们提议观测5个亮度最高的CT AGN，其红移z小于0.2，且目前尚未进行高质量0.310keV的观测。这将使局部高亮度CT AGN的样本量增加3.5倍，极大地提升我们对最高积聚速率下CT遮蔽的了解。这些观测将有助于约束CT AGN亮度函数的最亮端以及CT物质覆盖率的演变，同时亦将作为研究更高红移下明亮CT AGN的基准。请参阅实际数据以获取全文[截断，请参阅实际数据以获取全文]
