Abstract

Tidal disruption events (TDEs) are typically discovered in previously quiescent galaxies. However, earlier studies have revealed a handful of TDEs occurring in pre-existing active galactic nuclei (AGN). We discuss AT2019aalc, a promising TDE candidate in an AGN, and compare it to similar sources. We also explore Bowen fluorescence flares, a newly identified class of flaring supermassive black holes, as potential members of the TDE in AGN transient class. We aim to connect the observed properties of these flares with the expectations of TDE-in-AGN simulations.

不再隐藏：聚焦于活动星系核的潮汐破坏事件

潮汐破坏事件（TDEs）通常在以前静止的星系中发现。然而，早期的研究表明，少数tde发生在已经存在的活动星系核（AGN）中。我们讨论了AT2019aalc，这是AGN中一个很有前途的TDE候选源，并将其与类似源进行了比较。我们还探索了Bowen荧光耀斑，这是一种新发现的耀斑超大质量黑洞，作为AGN瞬态类TDE的潜在成员。我们的目标是将这些耀斑的观测特性与TDE-in-AGN模拟的期望联系起来。

期刊介绍： Astronomische Nachrichten, founded in 1821 by H. C. Schumacher, is the oldest astronomical journal worldwide still being published. Famous astronomical discoveries and important papers on astronomy and astrophysics published in more than 300 volumes of the journal give an outstanding representation of the progress of astronomical research over the last 180 years. Today, Astronomical Notes/ Astronomische Nachrichten publishes articles in the field of observational and theoretical astrophysics and related topics in solar-system and solar physics. Additional, papers on astronomical instrumentation ground-based and space-based as well as papers about numerical astrophysical techniques and supercomputer modelling are covered. Papers can be completed by short video sequences in the electronic version. Astronomical Notes/ Astronomische Nachrichten also publishes special issues of meeting proceedings.
