最好的汤是在最古老的锅里煮的:重温类星体的档案HST/FOC观测

The best broths are cooked in the oldest pans: revisiting the archival HST/FOC observations of quasars

摘要:

哈勃太空望远镜(HST)上的暗天体照相机(FOC)在1990年至2002年期间通过紫外成像偏振测量法观测了26个单独的活动星系核(AGN)。由于这些高空间分辨率、高信噪比的观测,已经取得了巨大的进展,例如确定了隐藏的活动核的位置和围绕中央核心的前一百秒差距内的极性物质的三维排列。然而,并不是所有的活动星系核观测都被简化和分析,也没有一个标准化的框架。在这篇演讲稿中,我们提出了我们的项目下载,减少和分析所有AGN HST/FOC观测,使用一致的,新颖的和开放访问的减少管道。我们简要介绍了我们的方法,并显示了我们的还原管道的第一个初步结果:NGC 1068。

英文摘要:

The Faint Object Camera (FOC) aboard the Hubble Space Telescope (HST) observed 26 individual active galactic nuclei (AGNs) in ultraviolet imaging polarimetry between 1990 and 2002. Tremendous progresses have been made thanks to those high spatial resolution, high signal-to-noise ratio observations, such as the identification of the location of hidden active nuclei and the three dimensional arrangement of polar material within the first hundred of parsecs around the central core. However, not all AGN observations have been reduced and analyzed, and none in a standardized framework. In this lecture note, we present our project of downloading, reducing and analyzing all the AGN HST/FOC observations that were achieved using a consistent, novel and open-access reduction pipeline. We briefly present our methodology and show the first, preliminary result from our reduction pipeline: NGC 1068.
