论文摘要

AGN是宇宙中最有活力的现象之一,在过去的二十年中,积分在他们的研究中的贡献产生了重大影响。多亏了整体外层次的天空调查,在较高的能量上也观察到了所有类别的软X射线(在2-10 KEV带中)AGN。到目前为止,大约有450个AGN已被分类,其中一个显着的部分是首次在高碳中观察到的对象,或者是新发现的AGN。高能量结构域(20-200 KEV)代表了AGN光谱研究的重要窗口,它也是AGN人群研究的最合适的窗口,因为它几乎没有偏见,因此没有影响其他频率调查的局限性。多年来,积分数据已允许在高能量处表征AGN光谱,以研究其吸收特性,测试AGN统一方案并进行人群研究。在本综述中,主要结果报告了,并且为每类AGN强调了积分对AGN科学的贡献。最后,提供了新的观点,将Integral的科学与其他波长联系起来,尤其是GEV/TEV制度的科学,而GEV/TEV制度仍然很差。

AGN are among the most energetic phenomena in the Universe and in the last two decades INTEGRAL's contribution in their study has had a significant impact. Thanks to the INTEGRAL extragalactic sky surveys, all classes of soft X-ray detected (in the 2-10 keV band) AGN have been observed at higher energies as well. Up to now, around 450 AGN have been catalogued and a conspicuous part of them are either objects observed at high-energies for the first time or newly discovered AGN. The high-energy domain (20-200 keV) represents an important window for spectral studies of AGN and it is also the most appropriate for AGN population studies, since it is almost unbiased against obscuration and therefore free of the limitations which affect surveys at other frequencies. Over the years, INTEGRAL data have allowed to characterise AGN spectra at high energies, to investigate their absorption properties, to test the AGN unification scheme and to perform population studies. In this review the main results are reported and INTEGRAL's contribution to AGN science is highlighted for each class of AGN. Finally, new perspectives are provided, connecting INTEGRAL's science with that at other wavelengths and in particular to the GeV/TeV regime which is still poorly explored.
