In July 2018, IceCube announced compelling evidence of the first astronomical high-energy neutrino source. Through this multi-messenger effort, one learns that in order to become a true partner in multi-messenger astronomy, neutrinos need to resolve more than a handful of sources to understand which source types are dominant, and neutrinos must be sensitive enough on their own to make statements about these sources. With those goals in mind, this award develops a new channel of source localization analysis using IceCube data, namely cascade events, that is completely independent of the ones used in traditional source searches. This has the potential of doubling IceCube's source search capacity. A planned upgrade of the detector will further enhance the sensitivities of cascade analyses, making the development of this analysis channel an urgent priority. Establishing the first catalog of high-energy neutrino sources will make neutrinos a powerful and integral part of multi-messenger astronomy.The IceCube experiment provides diverse, yet accessible science topics suitable for undergraduate and post-bac research. The PI has a long record of public outreach that will continue with this program. The PI recognizes that the practice of inclusion in a research environment, such as a large collaboration, will ultimately result in better science. She understands the impact she can have, particularly on young women and girls, by simply being a visible face of a physicist. She is committed to carrying out an effective and meaningful science program as well as an impactful broader impacts program through IceCube.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.

2018年7月，IceCube宣布了第一个天文高能中微子源的令人信服的证据。 通过这种多信使的努力，人们了解到，为了成为多信使天文学的真正合作伙伴，中微子需要解决超过少数的来源，以了解哪些来源类型是占主导地位的，中微子必须足够敏感，自己对这些来源作出声明。考虑到这些目标，该奖项使用IceCube数据开发了一种新的源本地化分析渠道，即级联事件，完全独立于传统源搜索中使用的源。这有可能使IceCube的源搜索能力翻一番。计划中的探测器升级将进一步提高级联分析的灵敏度，使开发这一分析通道成为当务之急。建立第一个高能中微子源目录将使中微子成为多信使天文学的一个强大而不可或缺的组成部分。IceCube实验提供了适合本科生和后bac研究的多样化但可访问的科学主题。PI有一个长期的公共宣传记录，将继续与这个计划。PI认识到，在研究环境中的包容性实践，如大型合作，最终将导致更好的科学。她明白自己可以产生的影响，特别是对年轻妇女和女孩，仅仅是作为一个物理学家的可见面孔。她致力于通过IceCube开展有效且有意义的科学计划以及有影响力的更广泛影响计划。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响力进行评估而被认为值得支持。审查标准。
