Mrk 509上的多波长活动。III。600 k S RGS谱：解开AGN的内部区域
Multiwavelength campaign on Mrk 509. III. The 600 ks RGS spectrum: unravelling the inner region of an AGN
摘要：
我们目前的结果，我们的600 KS RGS观测的一部分，Mrk 509的多波长运动。由于长时间曝光和使用RGS多点模式，非常高质量的光谱使我们能够以前所未有的精度研究电离流出。我们探测到来自星际介质和Mrk 509电离吸收体的多条吸收线。还检测到许多发射分量，包括与宽线区域中的原点一致的宽发射线、窄OVII禁止发射线以及（窄）辐射复合连续体。电离吸收体由两个速度分量组成（v = -13 \pm 11 km/s和v = -319 \pm 14 km/s），这两个分量与包括紫外数据在内的早期结果一致。另外还有一个实验性的高速流出分量，-770 \pm 109 km/s，这只在少数几条高电离吸收线中看到。外流显示离散电离组件，跨越四个数量级的电离参数。由于我们的光谱的出色的统计，我们证明了第一次，流出Mrk 509在1-3之间的重要范围内的log xi不能描述一个平滑的，连续的吸收测量分布，而是显示出两个强大的，离散的峰。在最高和最低电离参数下，我们无法区分光滑和分立元件。
英文摘要：
We present the results of our 600 ks RGS observation as part of the multiwavelength campaign on Mrk 509. The very high quality of the spectrum allows us to investigate the ionized outflow with an unprecedented accuracy due to the long exposure and the use of the RGS multipointing mode. We detect multiple absorption lines from the interstellar medium and from the ionized absorber in Mrk 509. A number of emission components are also detected, including broad emission lines consistent with an origin in the broad line region, the narrow OVII forbidden emission line and also (narrow) radiative recombination continua. The ionized absorber consists of two velocity components (v = -13 \pm 11 km/s and v = -319 \pm 14 km/s), which both are consistent with earlier results, including UV data. There is another tentative component outflowing at high velocity, -770 \pm 109 km/s, which is only seen in a few highly ionized absorption lines. The outflow shows discrete ionization components, spanning four orders of magnitude in ionization parameter. Due to the excellent statistics of our spectrum, we demonstrate for the first time that the outflow in Mrk 509 in the important range of log xi between 1-3 cannot be described by a smooth, continuous absorption measure distribution, but instead shows two strong, discrete peaks. At the highest and lowest ionization parameters we cannot differentiate smooth and discrete components.
