论文摘要

奶奶是全球合作,其主要科学目标是研究重力波来源,发现其电磁对应物并表征其排放。奶奶涉及天文学家,天体物理学家,引力波物理学家和理论家。奶奶现在是一个真正的全球望远镜网络,到目前为止,两个半球都有30个望远镜。它结合了一项公民科学计划(Kilonova-Catcher),该计划构成了传播对时间域天文学兴趣的机会。望远镜网络是一组已经存在的观测设施,该设施作为单个天文台进行了协调。在网络中,有宽大的成像仪可以观察天空的大面积,以寻找光学对应物,狭窄场仪器,这些仪器在预定义的宿主 - 高拉克斯候选者列表中进行有针对性的搜索,以及用于表征和随访的较大望远镜的望远镜。在这里,我们在2019-2020美元的第三次观察中介绍了Ligo/处女座重力波观察站的第三次观察之后,概述了奶奶,并为即将到来的第四次观察运动(O4)进行了持续的准备。此外,我们回顾了奶奶对其他类型的天文瞬变的发现和随访的潜力。

GRANDMA is a world-wide collaboration with the primary scientific goal of studying gravitational-wave sources, discovering their electromagnetic counterparts and characterizing their emission. GRANDMA involves astronomers, astrophysicists, gravitational-wave physicists, and theorists. GRANDMA is now a truly global network of telescopes, with (so far) 30 telescopes in both hemispheres. It incorporates a citizen science programme (Kilonova-Catcher) which constitutes an opportunity to spread the interest in time-domain astronomy. The telescope network is an heterogeneous set of already-existing observing facilities that operate coordinated as a single observatory. Within the network there are wide-field imagers that can observe large areas of the sky to search for optical counterparts, narrow-field instruments that do targeted searches within a predefined list of host-galaxy candidates, and larger telescopes that are devoted to characterization and follow-up of the identified counterparts. Here we present an overview of GRANDMA after the third observing run of the LIGO/VIRGO gravitational-wave observatories in $2019-2020$ and its ongoing preparation for the forthcoming fourth observational campaign (O4). Additionally, we review the potential of GRANDMA for the discovery and follow-up of other types of astronomical transients.
