MWA Galactic Plane Data 2013-2022

Recently, new classes of Galactic radio transients have been discovered, some of which are entirely unexpected and are of high scientific interest. Searching back through nearly a decade of MWA data has recovered very long-term measurements of these sources -- beyond what is often even possible with other observatories, due to the MWA's wide field of view. These measurements are important for constraining the physical properties of the sources, which allows us to understand their nature and explore their astrophysics. Since we do not yet know what new transients will be discovered in the future, we should store all of these data in perpetuity, so that they can always be searched, as new techniques are developed.近年来，科研人员发现了多类全新的银河系射电暂现源，其中不乏完全出乎意料的天体，具备极高的科学研究价值。通过回溯近十年的默奇森宽场阵列（Murchison Widefield Array，MWA）观测数据，我们获取了这些暂现源的超长时程测量数据——得益于该阵列宽广的视场，这类测量的时间跨度远超其他观测台站所能实现的水平。此类测量数据对约束该类天体的物理属性至关重要，能够帮助我们明确其本质并深入探索其天体物理机制。鉴于目前我们尚无法预知未来将发现何种新型暂现源，因此应当永久留存所有此类数据，以便随着新技术的发展，始终能够对其进行检索与再分析。
