摘要

我们研究了著名且研究充分的3C31类FRI射电星系的近距离，以揭示环境对河外射电源的影响。研究表明，大约1.1亿年前，星系NGC 380和NGC 386位于星系NGC 383（3C31的母星系）附近。另一方面，对无线电星系3C31中心部分无线电发射光谱特征的建模给出了中心喷流年龄约1亿年的估计。因此，可以假设NGC383星系放射性出现或恢复的可能原因之一可能是星系的三重近距离通过。

On a Possible Mechanism for the Start or Resumption of Activity of Radio Galaxies in Clusters of Galaxies

We study the close proximity of the well-known and well-studied 3C31 class FRI radio galaxy in order to reveal the influence of the environment on an extragalactic radio source. It was shown that about 110 million years ago the galaxies NGC 380 and NGC 386 were located near the galaxy NGC 383 (the parent galaxy of 3C31). On the other hand, the modeling of the spectral characteristics of the radio emission of the central part of the radio galaxy 3C31 gives an estimate of the age of the central jet of about 100 million years. Therefore, it can be assumed that one of the possible reasons for the appearance or resumption of the radioactivity of the galaxy NGC 383 may be a triple close passage of galaxies.

期刊介绍： Astrophysics (Ap) is a peer-reviewed scientific journal which publishes research in theoretical and observational astrophysics. Founded by V.A.Ambartsumian in 1965 Astrophysics is one of the international astronomy journals. The journal covers space astrophysics, stellar and galactic evolution, solar physics, stellar and planetary atmospheres, interstellar matter. Additional subjects include chemical composition and internal structure of stars, quasars and pulsars, developments in modern cosmology and radiative transfer.
