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.

最近对中子星合并产生的引力波和光的探测开启了多信使天体物理学的时代，提供了短伽马射线爆发、重元素产生以及致密塌缩物体（中子星）合并所引发的相对论流出起源的直接证据。和黑洞）。 这个新的发现空间将通过提高北半球引力波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。 这将通过在发出警报后使用卡特琳​​娜巡天系统快速定位这次发射的位置来实现，将其位置告知天文学界，并立即使用亚利桑那州天文台 (SAGURAO) 望远镜网络进行引力波搜索。 6.5mMMT、2x8 m LBT 以及夏威夷的 10 m Keck 等）通过深度成像和积分现场单元 (IFU) 监测这些事件光谱学。将开发一套优先考虑 EM 对应候选人进行后续观察的算法，以及一个提供集中位置的网站，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。 PI 将与芝加哥哈罗德华盛顿大学合作，为两名代表性不足的少数族裔社区学院学生提供为期两年的天文研究夏季课程，以培养他们的 STEM 技能。这笔赠款满足了北部地区 WoU-MMA 项目的需求半球。 它将组织亚利桑那州的天文观测资源，对用于观测引力波和中子星合并的光电磁窗口进行探测和定位。在收到 Ligo/Virgo 或 IceCube 的事件通知后，Catalina Sky Survey 将用于发现并快速定位光学对应物，并立即向天文学界发出警报。随后将使用亚利桑那州天文台引力波搜索 (SAGURAO) PI 联盟的观测，该联盟由位于亚利桑那州和夏威夷的望远镜设施以及其他设施组成，对光学对应物及其环境进行成像和光谱研究。将开发一套优先考虑 EM 对应候选者进行后续观察的算法，以及一个提供集中位置以实时组织候选者并向科学界传播信息的网站，以确保协调这项研究的资源。该计划推进了 NSF 宇宙大创意之窗的目标。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
