FERO(寻找极端相对论天体):AGN中相对论性宽Fe K α谱线的统计

FERO (Finding Extreme Relativistic Objects): statistics of relativistic broad Fe K alpha lines in AGN

A. L. Longinotti, I. de La Calle, S. Bianchi, M. Guainazzi, M. Dovciak

摘要:

活动星系核(AGN)中相对论性增宽的Fe K α线的性质在活动星系核学界仍有争议。最近的工作似乎排除了宽Fe线是活动星系核的共同特征。本文分析了由157个XMM-牛顿射电静活动星系核观测资料组成的大样本。这个正在进行的项目是Guainazzi等人2006年报告的工作的发展。

英文摘要:

The properties of the relativistically broadened Fe K alpha line emitted in Active Galactic Nuclei (AGN) are still debated among the AGN community. Recent works seem to exclude that the broad Fe line is a common feature of AGN. The analysis of a large sample composed by 157 XMM-Newton archival observations of radio quiet AGN is presented here. This ongoing project is a development of the work reported in Guainazzi et al. 2006.
