论文摘要
我们介绍了Swift BAT AGN光谱调查（Bass DR2）的第二个数据释放的AGN目录和光谱。在此DR2发行版中，我们提供了1425个光谱，其中首次发布了1181个光谱，其中858个硬X射线选择的AGN在Swift BAT 70个月的样本中选择了AGN。大多数光谱（813/1425，57％）是从VLT/Xshooter或Palomar/Doublespec新获得的。许多光谱都具有较高的分辨率（R> 2500，N〜450）和/或非常宽的波长覆盖率（3200-10000 A，N〜600），这对于各种AGN和宿主星系研究都很重要。我们包括新修订的AGN对应物，用于完整样本，并查看人口研究的重要问题，首次确定了44个AGN红移，并估计了780个黑洞质量和增值率。对于所有AGN（100％，858/858），该版本在光谱上完成，其中99.8％的红移测量值（857/858）和96％的未打印AGN的黑洞质量估计值（在银河平面之外）中完成了96％。该AGN样本代表了天空中最亮的X射线X射线AGN的独特人口普查，涵盖了Eddington比率的许多数量级（LEDD = 10^-5-100），黑洞质量（MBH = 10^5-10^10 MSUN），以及AGN抛光光度（LBOL = 10^40-10^40-10^47 ERGS/S）。
We present the AGN catalog and optical spectroscopy for the second data release of the Swift BAT AGN Spectroscopic Survey (BASS DR2). With this DR2 release we provide 1425 optical spectra, of which 1181 are released for the first time, for the 858 hard X-ray selected AGN in the Swift BAT 70-month sample. The majority of the spectra (813/1425, 57%) are newly obtained from VLT/Xshooter or Palomar/Doublespec. Many of the spectra have both higher resolution (R>2500, N~450) and/or very wide wavelength coverage (3200-10000 A, N~600) that are important for a variety of AGN and host galaxy studies. We include newly revised AGN counterparts for the full sample and review important issues for population studies, with 44 AGN redshifts determined for the first time and 780 black hole mass and accretion rate estimates. This release is spectroscopically complete for all AGN (100%, 858/858) with 99.8% having redshift measurements (857/858) and 96% completion in black hole mass estimates of unbeamed AGN (outside the Galactic plane). This AGN sample represents a unique census of the brightest hard X-ray selected AGN in the sky, spanning many orders of magnitude in Eddington ratio (Ledd=10^-5-100), black hole mass (MBH=10^5-10^10 Msun), and AGN bolometric luminosity (Lbol=10^40-10^47 ergs/s).
