Evidence of Outflow Induced Soft Lags of Galactic Black Holes

摘要:

银河系黑洞滞后变化的本质仍然是谜,主要是因为非线性和非局域的物理机制,这有助于从靠近中心黑洞的区域来的光子的滞后。被广泛接受的硬滞后的主要来源之一是逆康普顿化机制。然而,软滞后的确切原因尚待确定。在本文中,我们报告了几个爆发的银河系黑洞候选者的无线电强度和软滞后量之间的可能相关性。相关性表明,存在的主要流出或射流也改变磁盘形态沿视线的观察者产生软滞后。

英文摘要:

The nature of lag variation of Galactic black holes remains enigmatic mostly because of nonlinear and non-local physical mechanisms which contribute to the lag of the photons coming from the region close to the central black holes. One of the widely accepted major sources of the hard lag is the inverse Comptonization mechanism. However, the exact reason or reasons for soft lags is yet to be identified. In this paper, we report a possible correlation between radio intensities of several outbursting Galactic black hole candidates and amounts of soft lag. The correlation suggests that the presence of major outflows or jets also change the disk morphology along the line of sight of the observer which produces soft lags.
