The recent detection of Gravitational Waves and light from a neutron star merger opens up the era of multimessenger astrophysics with direct evidence for the origin of short gamma ray bursts, heavy element production, and relativistic outflows launched from the mergers of compact collapsed objects (neutron stars and black holes). This new discovery space will be optimized by increasing the detection rate and monitoring of the electromagnetic (EM) counterparts of GW and high energy neutrino events in the northern hemisphere. This will be accomplished by rapidly locating the position of this emission using the Catalina Sky Survey after an alert, informing the astronomical community of its location and immediately bringing on-line the Searches After Gravitational-waves Using Arizona's Observatories (SAGURAO) network of telescopes ( 6.5mMMT, 2x8 m LBT, as well as the 10 m Keck in Hawaii and others) to monitor these events with deep imaging and integral field unit (IFU) spectroscopy. A set of algorithms to prioritize EM counterpart candidates for follow-up observation and a website to provide a centralized location to organize candidates in real time to disseminate the information to the scientific community will be developed to insure coordination of resources for this research. The PIs will partnership with Harold Washington University in Chicago to mentor two underrepresented minority community college students by providing them with a two year summer course on astronomical research to develop their STEM skills.The grant addresses the needs of the WoU-MMA program in the northern hemisphere. It will organize the astronomical observational resources in Arizona to detect and localize the optical electromagnetic window for the observation of gravitational waves and neutron star mergers. After being informed of an event by Ligo/Virgo or IceCube, the Catalina Sky Survey will be used to discover and quickly localize the optical counterpart and immediately send out an alert to the astronomical community. This will be followed by observations using the Searches After Gravitational-waves Using Arizona's Observatories (SAGURAO) PIs consortium of telescope facilities in Arizona and Hawaii as well as other facilities to image and spectroscopically study the optical counterparts and their environments. A set of algorithms to prioritize EM counterpart candidates for follow-up observation and a website to provide a centralized location to organize candidates in real time and disseminate the information to the scientific community will be developed to insure coordination of resources for this research. This program advances the goals of the NSF Windows on the Universe Big-Idea.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

最近探测到的引力波和来自中子星合并的光开启了多信使天体物理学的时代，为短伽马射线爆发、重元素产生和致密坍塌物体(中子星和黑洞)合并引发的相对论外流的起源提供了直接证据。这一新的发现空间将通过提高对北半球GW和高能中微子事件的电磁(EM)对应物的探测率和监测来优化。这将通过在警报后使用Catalina Sky Survey快速定位该辐射的位置，通知天文学团体其位置，并立即使用亚利桑那州天文台(SAGURAO)望远镜网络(6.5mMMT、2x8m LBT以及夏威夷的10米Keck望远镜等)在引力波之后进行搜索，以利用深度成像和积分场单元(IFU)光谱学监测这些事件。将制定一套算法，为后续观察确定新兴市场对应候选人的优先次序，并建立一个网站，提供一个集中地点，以实时组织候选人向科学界传播信息，以确保协调这项研究的资源。PIS将与芝加哥的哈罗德·华盛顿大学合作，通过为两名未被充分代表的少数族裔社区大学生提供为期两年的天文研究暑期课程来发展他们的STEM技能，以指导他们。这笔赠款满足了Wou-MMA项目在北半球的需求。它将组织亚利桑那州的天文观测资源，以探测和定位观测引力波和中子星合并的光学电磁窗口。在收到LIGO/处女座或IceCube的事件通知后，Catalina Sky Survey将被用来发现光学对应物并快速定位，并立即向天文学社区发出警报。随后将利用亚利桑那州天文台(SAGURAO)PI集团在亚利桑那州和夏威夷的望远镜设施以及其他设施对光学对应物及其环境进行成像和光谱研究，进行引力波后的观测。将开发一套算法，为后续观察确定新兴市场对应候选人的优先顺序，并建立一个网站，提供一个集中地点，实时组织候选人并向科学界传播信息，以确保协调这项研究的资源。这项计划推进了NSF宇宙大理想之窗的目标。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
