引力波候选者的电磁跟踪：INAF的前景
Electromagnetic follow-up of gravitational wave candidates: perspectives in INAF
摘要：
伴随着引力波（GW）信号的电磁辐射是未来天文学的主要目标之一。中子星和/或黑洞的合并以及大质量恒星的核心坍缩预计会引起快速瞬变电磁信号。GW信号的EM后续将不得不处理大的位置不确定性。引力天空定位预计为数十至数百平方度。宽视场相机和快速跟踪观察对于确定第一次EM对应物鉴定的EM候选物的特征至关重要。我们提出了一些我们目前正在进行的活动，以优化INAF设施网络对预期GW触发的响应。国际原子能机构网络将是一个有效的业务框架，能够对大的错误箱触发器作出快速反应，并直接识别和描述候选人。
英文摘要：
The electromagnetic (EM) emission associated with a gravitational wave (GW) signal is one of the main goal of future astronomy. Merger of neutron stars and/or black holes and core-collapse of massive stars are expected to cause rapid transient electromagnetic signals. The EM follow-up of GW signals will have to deal with large position uncertainties. The gravitational sky localization is expected to be tens to hundreds of square degrees. Wide-field cameras and rapid follow-up observations will be crucial to characterize the EM candidates for the first EM counterpart identification. We present some of the activities that we are currently carrying on to optimize the response of the INAF network of facilities to expected GW triggers. The INAF network will represent an efficient operational framework capable of fast reaction on large error box triggers and direct identification and characterization of the candidates.
