我们提出了新的XMM-牛顿数据的高红移（z = 1.883），百万pc大小的巨型射电星系6C 0905+39。我们的新数据的更大的收集面积和更长的观测时间意味着我们可以更好地表征扩展的X射线发射，特别是它的光谱，这是由宇宙微波背景光子散射到X射线波段中产生的，这些光子是由6C 0905+39的（大部分）无线电安静波瓣的废同步加速器等离子体中的高能电子散射到X射线波段中的。我们计算的能量，其喷射等离子体倾倒到周围环境中，在过去的3 × 10 - 7年，并讨论了类似的，甚至更极端的例子，花，无线电安静的叶会对他们的周围环境的影响。有趣的是，有迹象表明，从热点的发射比其余的扩展发射和核心，这意味着它是由于同步辐射。我们证实了我们先前在6C 0905+39东部热点中检测到的低能量周转。
We present new XMM-Newton data of the high-redshift (z = 1.883), Mpc-sized giant radio galaxy 6C 0905+39. The larger collecting area and longer observation time for our new data means that we can better characterize the extended X-ray emission, in particular its spectrum, which arises from cosmic microwave background photons scattered into the X-ray band by the energetic electrons in the spent synchrotron plasma of the (largely) radio-quiet lobes of 6C 0905+39. We calculate the energy that its jet-ejected plasma has dumped into its surroundings in the last 3 x 10 7 yr and discuss the impact that similar, or even more extreme, examples of spent, radio-quiet lobes would have on their surroundings. Interestingly, there is an indication that the emission from the hotspots is softer than the rest of the extended emission and the core, implying it is due to synchrotron emission. We confirm our previous detection of the low-energy turnover in the eastern hotspot of 6C 0905+39.
