From Hubble Space Telescope/Cosmic Origins Spectrograph spectra of five quasars, 16 outflows are detected. For 11 outflows, we are able to constrain their distances to the central source ( R ) and their energetics. In instances of multiple electron number density determinations (used in the calculation of R ) for the same outflow, the values are consistent within errors. For the 11 outflows, eight have measurements for R (between 10 and 1000 pc), one has a lower limit, another has an upper limit, and the last has a range in R . There are two outflows that have enough kinetic luminosity to be major contributors to active galactic nucleus feedback. The outflowing mass is found primarily in a very high-ionization phase, which is probed using troughs from, e.g., Ne viii , Na ix , Mg x , and Si xii . Such ions connect the physical conditions of these ultraviolet out...

HST / COS在500–1050Å静止框架中类星体流出的观测结果。七。5个类星体中11个流出的距离和能量学

从哈勃太空望远镜/宇宙起源光谱仪的五个类星体光谱中,检测到16个流出。对于11个流出,我们可以限制它们到中心源(R)的距离及其能量。对于同一流出,在多次电子数密度测定(用于R的计算中)的情况下,这些值在误差范围内是一致的。对于11个流出,有八个测量R(在10到1000 pc之间),一个具有下限,另一个具有上限,最后一个具有R范围。有两个流出物具有足够的动力学发光度,从而成为主动银河核反馈的主要贡献者。发现流出的物质主要是在非常高的电离阶段,可以使用例如Ne viii,Na ix,Mg x和Si xii的谷来探测。
