摘要:

平谱射电类星体B2 1633+382(4C 38.41)已经被监测了好几年,并在多个波长上呈现出相关的变化。在这篇文章中,我们对多个频率进行了不同的分析,从伽马射线到无线电,以及C IV $λ$ 1549飞秒发射线和$λ$ 1350飞秒连续谱。当连续谱的主要来源是吸积盘或喷流时,我们利用非热优势参数分离了CIV和连续谱光变曲线。我们发现了一个相关性在延迟一致的零之间的线和连续占主导地位的磁盘发射指示一个非常小的宽线区域(BLR)。根据15 GHz和伽马射线之间的延迟,我们估计伽马射线发射区到喷流顶点的距离为$\sim$ 37 pc。当连续谱和γ射线在某些高活动期增加时,C IV通量减小。CIV型在其蓝翼中呈现出较大的可变分量。C IV的光度与连续谱的关系并不完全遵循类星体样品的关系。我们的研究结果使我们提出了一个外流的BLR材料的喷流方向,伽马射线生产通过磁重联的耀斑事件2011年中期,并没有足够的BLR材料靠近无线电核心容易被电离的非热连续。

英文摘要:

The flat-spectrum radio quasar B2 1633+382 (4C 38.41) has been monitored for several years and has presented correlated variability in multiple wavelengths. In this article, we are performing different analyses for multiple frequencies, from gamma-rays to radio, as well as, the C IV $λ$1549 Å emission line and the $λ$1350 Å continuum. Using the non-thermal dominance parameter, we separated the C IV and the continuum light curves for when the dominant source of continuum is the accretion disk or the jet. We found a correlation at a delay consistent with zero between the line and the continuum dominated by disk emission indicating a very small broad-line region (BLR). From the resulting delay between the 15 GHz and gamma-rays, we estimated the distance of the gamma-ray emission region from the jet apex to be $\sim$37 pc. The C IV flux decreases when the continuum and gamma-rays increase at some of the high activity periods. The C IV profile presents a larger variable component in its blue wing. The relation between the luminosities of C IV and the continuum does not completely follow the relation for a quasar sample. Our results lead us to propose an outflow of BLR material in the jet-flow direction, a gamma-ray production through magnetic reconnection for the flaring event of mid-2011, and that there is not enough BLR material close to the radio core to be easily ionized by the non-thermal continuum.
