论文摘要

由于电磁观测(EM)不再是探索宇宙的唯一方法,因此多理智的天文学是一个广阔而扩大的领域。由于新的使者,带有引力波(GWS)和EM排放的天体物理事件不再是天文学界的梦想。 GW多通信天文学的突破是在Ligo-Virgo网络检测到与二进制中子星(BNS,GW170817)一致的两个低质量紧凑物体的GW信号时,这是一个产生短的伽马射线爆发(GRBS)和Kilonova的事件。虽然GW170817代表了BNS合并是至少一些GRB的祖先的证词,但预计将伴随着GWS和光子的发射。在这里,我们提出了一种使用Ligo-Virgo数据和合作伙伴望远镜观察的GWS搜索具有伽马和无线电对应物的GW的方法。我们还讨论了针对天体物理事件的最新结果,该搜索针对了第三次观察跑(O3A)的第一部分:Fermi和Swift卫星检测到的105 GRB。

Multi-messenger astronomy is a vast and expanding field as electromagnetic observations (EM) are no longer the only way of exploring the Universe. Due to the new messengers, astrophysical events with both gravitational waves (GWs) and EM emission are no longer a dream of the astronomical community. A breakthrough for GW multi-messenger astronomy came when the LIGO-Virgo network detected a GW signal of two low-mass compact objects consistent with a binary neutron star (BNS, GW170817) an event that generated a short gamma-ray burst (GRBs) and a kilonova. While GW170817 represents the testimony to BNS mergers being the progenitor of at least some GRBs, a wide range of highly energetic astrophysical phenomena is expected to be accompanied by the emission of GWs and photons. Here we present an unmodelled method to search for GWs having gamma and radio counterparts, using the LIGO-Virgo data and observations of partner telescopes. We also discuss the most recent results of the unmodelled coherent searches targeting astrophysical events during the first part of the LIGO-Virgo third observing run (O3a): 105 GRBs detected by the Fermi and Swift satellites.
