Abstract

Several years ago a series of powerful millisecond radio bursts with close dispersion measures was detected toward the galaxy M31. Taking the hypothesis about the possible association of these radio bursts with a magnetar in M31 as a starting point, we have searched for periodic X-ray signal sources using data from the XMM-Newton X-ray telescope. As a result of our data analysis, we have identified a signal from the already known periodic X-ray source 3XMM J004301.4+413017, an accreting pulsar in a binary system. However, we have failed to detect new candidates. In particular, we have revealed no object that could be associated with the hypothetical magnetar responsible for the observed radio bursts that could have a luminosity \(L_{X}>10^{36}\) erg s\({}^{-1}\).

基于XMM-牛顿数据在银河M31中搜索磁铁作为周期性X射线源

摘要

几年前，朝着星系M31探测到一系列强大的毫秒无线电爆发，并采取了紧密的分散措施。以这些无线电脉冲可能与M31中的磁星相关联的假设为出发点，我们使用来自XMM-Newton X射线望远镜的数据搜索了周期性X射线信号源。数据分析的结果是，我们从已知的周期性X射线源3XMM J004301.4 + 413017中识别出一个信号，该信号是二进制系统中的积聚脉冲星。但是，我们没有发现新的候选人。特别是，我们没有发现与假设的磁星有关的物体，该磁星负责观察到的无线电脉冲，其发光度为\（L_ {X}> 10 ^ {36} \） erg s \（{} ^ {- 1} \）。
