Blazars are amazing cosmic events where powerful jets shoot out from the vicinity of the extremely large black holes located at the centers of galaxies. Scientists funded by the NSF recently found a very evasive particle called a neutrino coming from a blazar named TXS 0506+056. The investigators will use advanced computer simulations to study blazars in detail to unlock the secrets of these sources and make predictions for future discoveries. Undergraduate students at Purdue University will have the chance to actively take part in this exciting research. The investigators will also engage with high school students through the Saturday Morning Astrophysics Program at Purdue University.Blazars, relativistic jets from active galactic nuclei pointing very close to our line of sight, are among the most powerful cosmic particle accelerators in the Universe. They exhibit very bright, highly variable, nonthermal-dominated emission across the entire electromagnetic spectrum, indicating extreme particle acceleration in compact regions, often referred to as the blazar zone. This proposed program will study neutrino blazars combining MHD, PIC, particle transport, and polarized radiation transfer simulations. These simulations are designed to track the cosmic ray acceleration and transport, thus identify temporal correlation between neutrinos and multi-wavelength signatures as well as characteristic radiation patterns for neutrino blazars. This approach therefore leverages current observational efforts to reveal underlying blazar zone physics, and provides solid predictions for future multi-messenger discoveries. The project will offer research opportunities for undergraduate students at Purdue University. The wide context of the proposal equally allows for analytical and numerical projects as well as comparison with observations, so that undergraduates can pick the opportunity that fits their main interest. The Co-PI will also participate in outreach with high school students via the Saturday Morning Astrophysics Program at Purdue University. A new annual activity will be introduced connected to the topic of special relativity. It will involve presentations by the faculty and graduate students where the main concepts will be highlighted. The students will then be involved with hands-on, table-top activities where they can absorb these concepts. This outreach activity will culminate with a half-day Astrophysics Camp for students in the third year of the project.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.

Blazars是令人惊叹的宇宙活动，在那里，强大的喷气式飞机从位于星系中心的极大黑洞附近射出。由NSF资助的科学家最近发现了一个非常回避的粒子，称为中微子，来自一个名为TXS 0506+056的大黄蜂。研究人员将使用高级计算机模拟详细研究Blazars，以解锁这些来源的秘密，并为未来的发现做出预测。普渡大学的本科生将有机会积极参加这项激动人心的研究。调查人员还将通过普渡大学的周六早晨的天体物理学计划与高中生互动。布拉萨尔人，来自活跃银河核的相对论喷射，非常靠近我们的视线，是宇宙中最强大的宇宙粒子加速器之一。它们在整个电磁频谱上表现出非常明亮的，高度可变的，非热为主导的发射，表明紧凑型区域中的极端颗粒加速度通常称为大黄体区。该提出的计划将研究组合MHD，PIC，颗粒传输和极化辐射转移模拟的中微子大部分。这些模拟旨在跟踪宇宙射线的加速度和运输，从而确定中微子和多波长特征之间的时间相关性以及中微子大机的特征辐射模式。因此，这种方法利用当前的观察努力来揭示基本的大弹药区域物理学，并为未来的多理智发现提供了可靠的预测。该项目将为普渡大学的本科生提供研究机会。该提案的广泛背景同样允许分析和数值项目以及与观察结果进行比较，因此本科生可以选择适合其主要兴趣的机会。 Co-Pi还将通过普渡大学的星期六早晨的天体物理学计划与高中生参加外展活动。将引入与特殊相对论主题有关的新年度活动。它将涉及教职员工和研究生的演讲，其中主要概念将得到强调。然后，学生将参与动手，桌面活动，在那里他们可以吸收这些概念。该项目的第三年，这项外展活动将以学生为学生的半天天体物理营地达到顶峰。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的评估标准来通过评估来获得支持的。
