局域宇宙中的Seyfert星系:从BeppoSAX到Simbol- X

The Seyfert galaxies in the local Universe: from BeppoSAX to Simbol-X

Mauro Dadina

摘要:

$BeppoSAX$在观测附近(z $\leq$ 0.1)Seyferts时发现的操作条件被复制用于$Simbol$ - $X$,以模拟任务的真实最终数据库。结果表明,即使在最坏的条件下,点的$Simbol$ - $X$档案将允许充分表征附近的塞弗特的高能光谱,最重要的是,获得坚实的结果R和Ec(基本模型的宇宙X射线背景,CXB)。对于$\sim$ 15天体,吸积盘倾角的测量将成为可能,从而可以直接测试活动星系核的统一模型。最后,将在至少$\sim$ 25个物体中研究反射分量的随时间变化的特征。

英文摘要:

The operational conditions found by $BeppoSAX$ in observing nearby (z$\leq$0.1) Seyferts were reproduced for $Simbol$-$X$ in order to simulate a realistic final database of the mission. The results indicate that, even in the worst conditions, the $Simbol$-$X$ archive of pointings will allow to fully characterize the high-energy spectrum of nearby Seyferts and, most importantly, to obtain solid results on R and Ec (fundamental to model the cosmic X-Ray background, CXB). The measurement of the inclination angle of the accretion disk will be possible for $\sim$15 objects allowing to directly test the unified models for AGN. Finally, the time-dependent characteristics of the reflected component will be studied in at least $\sim$25 objects.
