CAREER:Towards the First Astronomical Catalog of Neutrino Sources

2018年7月，冰立方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，中微子需要解析不止几个源才能了解哪些源是主导的，而且中微子必须自己足够敏感，才能对这些源发表声明。考虑到这些目标，该奖项开发了一种使用IceCube数据进行来源本地化分析的新渠道，即级联事件，完全独立于传统来源搜索中使用的渠道。这有可能使IceCube的源搜索能力翻一番。探测器的计划升级将进一步提高级联分析的灵敏度，使这一分析渠道的发展成为当务之急。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强大而不可或缺的一部分。冰立方实验提供了适合本科生和后BAC研究的各种但可访问的科学主题。PI有着长期的公众宣传记录，并将继续这一计划。国际和平研究所认识到，纳入研究环境的做法，例如大型合作，最终将带来更好的科学。她明白，仅仅是作为物理学家的一张明显的面孔，她就可以产生影响，特别是对年轻妇女和女孩。她致力于通过冰立方开展有效和有意义的科学计划以及有影响力的更广泛的影响计划。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。

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.
