活动星系核和微类星体中的喷流-喷流联系:中心热耀斑的可能性
Disk-Jet Connection in Agns and Microquasars: The Possibility of Thermal Flares in the Center
摘要:
我们讨论了活动星系核和微类星体中心热耀斑的可能性。我们目前正在进行的一项研究的初步结果,试图评估一个假设的可行性,表明在这些来源中观察到的某些耀斑起源于系统的中心,而不是在相对论射流。使用一个简单的玩具模型,我们再现光学耀斑的光变曲线非常相似的源中观察到的。该模型特别适合那些只有双峰光学耀斑的后一个峰有射电对应物的情况。
英文摘要:
We discuss the possibility of thermal flares in centers of AGNs and microquasars. We present preliminary results of an ongoing study trying to assess the feasibility of a hypothesis suggesting that certain flares observed in these sources originate in the very centers of the systems and not in the relativistic jets. Using a simple toy model we reproduce optical flares with lightcurves very similar to those observed in the sources. The model suits especially well those cases where only the latter peak of a double-peaked optical flare has a radio counterpart.
