项目摘要
The High-Altitude Water Cherenkov Observatory (HAWC) is located at 4100 m above sea level near Puebla, Mexico. The detector has monitored the gamma-ray and cosmic-ray sky in the energy range from 100 gigaelectronvolts (Gev) to 100 teraelectronvolts (Tev) with a nearly 100% duty cycle and a sensitivity unprecedented for a survey instrument, offering an exceptional view into the cosmos. This award provides funding for the UW–Madison HAWC group to research scientific areas in which HAWC can make unique contributions: a search for TeV halos surrounding middle-aged pulsars identified by radio and GeV gamma-ray observations and a search for microquasars. The key questions motivating these studies include: Are TeV halos a universal feature of middle-aged pulsars? What drives the formation of TeV halos? How do microquasars produce high-energy emissions? Can they emit other high-energy messengers such as neutrinos?The HAWC group is in the Wisconsin IceCube Particle Astrophysics Center (WIPAC), a scientific center at UW-Madison with researchers involved in a range of Particle Astrophysics projects, including the IceCube Observatory, the Askaryan Radio Array, the HAWC experiment, and the Cherenkov Telescope Array. The PI will join the vibrant education and outreach activities of the center and contribute to educating and training future leaders in the field of Particle Astrophysics. She will lead an effort to support women and gender minorities at the center. Along with other colleagues, she will initiate monthly or bi-monthly social events to gather up female and gender minority (such as people who are transgender or nonbinary) students, postdocs, and researchers at WIPAC. These diversity meetings will also be open and will facilitate interactions between the local undergraduates, graduate students, and researchers working in Particle Astrophysics.The study of TeV halos and microquasars is closely related to the understanding of high-energy neutrinos. A population of TeV–PeV neutrinos with astrophysical origin has been observed by the IceCube Observatory since 2013. The origin of the bulk of the IceCube neutrinos remains a mystery. Recent multi-messenger follow-up observations provide hints toward the first neutrino sources, including the blazar TXS 0506+056 and the VHE gamma-ray emitting region surrounding the pulsar PSR J1907.9+0602, MGRO J1908+06. With an overlapping energy window, HAWC’s observation of these two types of sources will provide important information for neutrino studies. The gamma-ray analyses will be combined with the study of high-energy neutrinos. Microquasars are also candidate neutrino sources. The PI will work with the IceCube group on the multi-messenger study of the VHE gamma-ray sources, and in particular, to explore the possibility of a joint analysis of HAWC and IceCube observations of the potential sources. As a first attempt, they will use the HAWC spectra to derive the number of expected neutrinos from each source, assuming that protons produce the gamma-ray emission. The results will be compared with the IceCube observation of these sources to understand the role of microquasars as high-energy neutrino emitters.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.
高海拔切伦科夫水观测站(HAWC)位于墨西哥普埃布拉附近海拔4100米的地方。该探测器监测了100吉电子伏(Gev)到100太电子伏(Tev)能量范围内的伽马射线和宇宙射线天空,其占空比接近100%,灵敏度对于测量仪器来说是前所未有的,提供了一个独特的宇宙视图。该奖项为威斯康星大学麦迪逊分校HAWC小组提供资金,用于研究HAWC可以做出独特贡献的科学领域:通过无线电和GeV伽玛射线观测发现的中年脉冲星周围的TeV晕,以及搜索微类星体。推动这些研究的关键问题包括:TeV光晕是中年脉冲星的普遍特征吗?是什么驱动了TeV光晕的形成?微类星体是如何产生高能辐射的?它们能发射出其他高能信使,比如中微子吗?HAWC小组位于威斯康星冰立方粒子天体物理中心(WIPAC),这是威斯康星大学麦迪逊分校的一个科学中心,研究人员参与了一系列粒子天体物理项目,包括冰立方天文台、阿斯卡扬射电阵列、HAWC实验和切伦科夫望远镜阵列。PI将加入该中心充满活力的教育和推广活动,并为教育和培训粒子天体物理学领域的未来领导者做出贡献。她将在该中心领导一项支持女性和少数性别群体的工作。她将与其他同事一起,发起每月或每两个月一次的社交活动,聚集WIPAC的女性和性别少数群体(如跨性别者或非二元性别者)学生、博士后和研究人员。这些多样性会议也将是开放的,并将促进当地本科生,研究生和粒子天体物理学研究人员之间的互动。TeV晕和微类星体的研究与高能中微子的认识密切相关。自2013年以来,冰立方天文台已经观测到一群具有天体物理起源的TeV-PeV中微子。大部分冰立方中微子的来源仍然是个谜。最近的多信使后续观测为第一批中微子源提供了线索,包括blazar TXS 0506+056和脉冲星PSR J1907.9+0602, MGRO J1908+06周围的VHE伽马射线发射区。利用重叠的能量窗口,HAWC对这两种源的观测将为中微子研究提供重要信息。伽马射线分析将与高能中微子的研究结合起来。微类星体也是候选的中微子源。PI将与冰立方小组合作,对VHE伽玛射线源进行多信使研究,特别是探索联合分析HAWC和冰立方对潜在源的观测的可能性。作为第一次尝试,他们将使用HAWC光谱,假设质子产生伽马射线发射,从每个源得出预期的中微子数量。这些结果将与冰立方对这些源的观测结果进行比较,以了解微类星体作为高能中微子发射器的作用。该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
