CAREER: Experimental Particle Astrophysics with High Energy Neutrinos in IceCube

中微子是独特的宇宙信使，在识别和理解宇宙中最强大的宇宙加速器的过程中，它补充了宇宙射线和伽马射线。该奖项将支持将在漫射天体物理电子和tau中微子能谱及其由半球描绘的特征方面产生新见解的研究。如果发现各向异性，将为最近发现的天体物理中微子的银河系和河外起源提供证据。能谱将证实或驳斥高能扩散中微子流量可能来源的理论模型预测的特征，也可能探索非标准模型物理。通过将前沿研究与教育和推广相结合，PI寻求拓宽SBU物理学生的职业前景，并扩大和多样化STEM领域的学生队伍。她将继续与成功的SBU女性科学与工程(WISE)计划进行富有成效的合作，该计划旨在增加STEM领域、教育和外展领域的女性人数和比例。一种面向WISE本科生的新型仪器组件，旨在缩小仪器导向体验中的性别差异，将在SBU和高需求地区的当地学校的教育用突然电离层扰动(太阳耀斑)监测站中纳入微控制器和云计算的创新。该研究计划将利用IceCube中的电子和tau中微子探测，目标是最近发现的高能中微子扩散通量的能量和味道特征。这些数据将产生对扩散中微子通量的气味成分的敏感性。作为这项研究计划的一部分，大气中微子通量将被测量到对迄今未观测到的瞬发分量敏感的高能区，并将使用一种新的方法来测量覆盖迄今无法到达的TeV-PeV中微子能量范围的中微子-核子截面。

Neutrinos are unique cosmic messengers that complement cosmic rays and gamma rays in the on-going quest to identify and understand the most powerful cosmic accelerators in the Universe. This award will support research that will yield new insights in the diffuse astrophysical electron and tau neutrino energy spectrum and its characteristics delineated by hemisphere. Anisotropy, if it is found, will provide evidence for a galactic and an extragalactic origin of the recently discovered astrophysical neutrinos. The energy spectrum will confirm or refute the characteristics predicted by theoretical models on the possible sources of the high-energy diffuse neutrino flux and may also probe non-'Standard Model' physics.By integrating forefront research with education and outreach, the PI seeks to broaden the career prospects for SBU physics students and to expand and diversify the pool of students in STEM fields. She will continue her productive collaboration with the successful SBU Women in Science and Engineering (WISE) program, designed to increase the number and fraction women in STEM fields, in education and outreach. A novel instrumentation component for WISE undergraduate students, designed to narrow the gender-gap in instrumentation-oriented experiences, will incorporate innovations in micro-controllers and 'cloud-computing' in Sudden Ionospheric Disturbance (solar flare) monitoring stations for educational use at SBU and local schools in high-need districts.This research program will utilize electron and tau neutrino detection in IceCube targeting the energy and flavor characteristics of the recently discovered diffuse flux of highly energetic neutrinos. The data will yield sensitivity to the flavor composition of the diffuse neutrino flux. As part of this research program, the atmospheric neutrino flux will be measured into the high-energy region that is sensitive to the thus-far unobserved prompt component and a novel method will be used to measure the neutrino-nucleon cross section covering the thus-far inaccessible TeV - PeV neutrino energy range.
