Over the past year, the discovery of the first electromagnetic counterparts to sources of gravitational waves and high-energy neutrinos has brought us to the new era of ”multi-messenger” astrophysics (MMA). These new events provide deep insights into astrophysics, meanwhile, lead to the development of astronomical data fusion techniques. Each messenger carries information from different observation process and fusing all messengers can therefore provide the best understanding of the celestial objects’ attributes and expose various astrophysical phenomena. Over the decades, for the full exploitation of multi-band astronomical data, advanced unified platforms and data fusion techniques have been developed and become a research topic of interest for the astronomical community. In this paper, we present a systematic review of the popular and state-of-the-art fusion methods and platforms in different formats of astronomical data, aiming to give a comprehensive introduction to the current progress in this field; at the same time, we put forward insightful prospects for future study of multi-messenger data fusion, hoping to provide new thoughts for researchers in MMA era.

天文数据融合：近期进展与未来展望——调查

在过去的一年里，引力波和高能中微子来源的第一个电磁对应物的发现将我们带入了“多信使”天体物理学（MMA）的新时代。这些新事件提供了对天体物理学的深刻见解，同时也促进了天文数据融合技术的发展。每个信使携带来自不同观测过程的信息，融合所有信使可以最好地了解天体的属性并揭示各种天体物理现象。几十年来，为了充分利用多波段天文数据，开发了先进的统一平台和数据融合技术，并成为天文界感兴趣的研究课题。在本文中，我们对不同格式的天文数据的流行和最先进的融合方法和平台进行了系统回顾，旨在全面介绍该领域的当前进展；同时，我们对多信使数据融合的未来研究提出了深刻的展望，希望为MMA时代的研究人员提供新的思路。
