The hypothesis is considered that the active galactic nuclei (AGNs) are wormhole (WH) mouths rather than supermassive black holes (SMBHs). We study the difference in the physical properties of such objects from those of AGNs with SMBH, as well as the the corresponding difference in observational data. Firstly, the radiative efficiency for some types of WHs (both static and rotating) can be significantly larger than the theoretical maximal value for the Kerr SMBHs. A number of AGNs is presented, for which the observational data can be interpreted as the result of the presence of WHs in them. Secondly, a sufficiently strong gamma radiation with a characteristic spectrum noticeably differing from that of AGNs jets, can be emitted from a static WH as a result of a collision of accreting flows of matter inside the WH.

活跃银河核中可能的虫洞候选者

该假设被认为是活跃的银河核（AGNs）是虫洞（WH）口，而不是超大质量黑洞（SMBHs）。我们研究了这类物体与带有SMBH的AGN的物理性质的差异，以及观测数据的相应差异。首先，某些类型的WH（静态和旋转）的辐射效率可能明显大于Kerr SMBH的理论最大值。提出了许多AGN，其观测数据可以解释为其中存在WH的结果。其次，由于WH内部物质积聚的碰撞，可以从静态WH发出足够强的，具有与AGN射流不同的特征光谱的伽马射线。
