3C390.3双峰宽H $α$吸积盘起源的进一步证据

Further Evidence for the Accretion Disk Origination of the Double-Peaked Broad H$α$ of 3C390.3

摘要:

在这封信中,在广泛接受的理论吸积盘模型的双峰发射体3C390.3,扩展的盘状BLR可以很好地分裂成10个环,然后从环的线和连续辐射之间的时间滞后估计,根据1995年左右的观测光谱。我们发现,在所测得的时滞(单位为光日)与环的通量加权半径(单位为${\rm R_G}$)之间存在一个很强的相关性,这与理论吸积盘模型的预期结果是一致的。此外,通过强相关性,独立地估计了3C390.3的黑洞质量为$\sim10^9{\rm M_{\odot}}$,与文献报道的黑洞质量相同.这为3C390.3双峰宽巴耳末线的吸积盘起源提供了进一步的有力证据。

英文摘要:

In the letter, under the widely accepted theoretical accretion disk model for the double-peaked emitter 3C390.3, the extended disk-like BLR can be well split into ten rings, and then the time lags between the lines from the rings and the continuum emission are estimated, based on the observed spectra around 1995. We can find one much strong correlation between the determined time lags (in unit of light-day) and the flux weighted radii (in unit of ${\rm R_G}$) of the rings, which is well consistent with the expected results through the theoretical accretion disk model. Moreover, through the strong correlation, the black hole masses of 3C390.3 are independently estimated as $\sim10^9{\rm M_{\odot}}$, the same as the reported black hole masses in the literature. The consistencies provide further evidence to strongly support the accretion disk origination of the double-peaked broad balmer lines of 3C390.3.
