论文摘要
我们探索了在狭窄的线Seyfert 1 Galaxy IRAS13224-3809中看到的高蓝色，可变吸收线的光盘起源。蓝光对应于约0.25c的速度。其他活性银河核中的此类特征通常被解释为超快流出（UFO）。速度当然存在于内部磁盘的轨道运动中。当通量较低并且磁盘的反射分量相对于幂律连续体时，iras13224-3809中的吸收线最好可见。光谱与一个模型一致，在该模型中，反射分量通过内盘表面的薄薄，高度离子的吸收层，该模型在内盘的表面上通过，其蓝移侧的蓝色侧面占据了相对论畸变引起的通量（圆盘倾斜度约为70度）。除了光盘之外，没有快速流出需求。
We explore a disc origin for the highly-blueshifted, variable absorption lines seen in the X-ray spectrum of the Narrow Line Seyfert 1 galaxy IRAS13224-3809. The blueshift corresponds to a velocity of about 0.25c. Such features in other Active Galactic Nuclei are often interpreted as UltraFast Outflows (UFOs). The velocity is of course present in the orbital motions of the inner disk. The absorption lines in IRAS13224-3809 are best seen when the flux is low and the reflection component of the disk is strong relative to the power-law continuum. The spectra are consistent with a model in which the reflection component passes through a thin, highly-ionized absorbing layer at the surface of the inner disc, the blue-shifted side of which dominates the flux due to relativistic aberration (the disc inclination is about 70 deg). No fast outflow need occur beyond the disc.
