Cavities comma strong shocks and AGN heating in galaxy groups

Outbursts of SMBHs have significant impact on structure formation and evolution.Their imprint on ICM (cavities, shocks and ^ated entropy) provides anhistorical chronicle of the SMBH activity. However, AGN heating has not beenwell studied in groups (especially for groups hosting strong radio AGN),although it should affect the group gas much more than the cluster gas. Wepropose XMM observations of two groups with strong radio AGN. Both have clearfeatures indicative of heating from the radio AGN in short XMM or Chandraexposures. The results will fill the little explored regime of the L_radio L_power plane for groups. One galaxy also has a mysterious emission line in thespectrum of its AGN, which needs to be tested and studied with deeper data. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]

超大质量黑洞的爆发对结构形成与演化具有重要影响。其在星系际介质（空洞、冲击波及增熵）上的烙印，构成了一部关于超大质量黑洞活动的编年史。然而，活动星系团中的 AGN 加热现象尚未得到充分研究（尤其是对于拥有强大射电 AGN 的星系团），尽管其应比团簇气体对团簇气体产生更大的影响。我们提议对两个拥有强大射电 AGN 的星系团进行 XMM 观测。这两个星系团在短时间的 XMM 或 Chandra 暴露下均展现出明显的 AGN 加热特征。这些结果将填补星系 L_radio-L_power 平面中尚未充分探索的区域。其中一颗星系在其 AGN 的光谱中还存在一条神秘的发射线，需要通过更深入的数据进行测试和研究。详细内容请参阅实际数据。[内容截断，请参阅实际数据获取全文]
