The primary objective of this U.S.-Poland research project between Dr. Mitchell Begelman of the University of Colorado, Boulder, and Dr. Marek Sikora of the Copernicus Astronomical Center, Warsaw, is to improve our understanding of the workings of active galactic nuclei. The researchers will do this by studying the astrophysical consequences of their hypothesis that relativistic protons are produced in quasars and other active galactic nuclei (AGNs). Their work should yield quantitative predictions about the fluxes of very high energy gamma rays and neutrinos. Detections of these particles would demonstrate the significance of relativistic hadrons in AGNs and potentially support the theory that they play a key role in formation of strong quasar winds. Results may solve several theoretical problems related to the observed galactic phenomena of BEL (broad emission line) and BAL (broad absorption line) regions. This project in extragalactic astronomy fulfills the program objective of advancing scientific knowledge by enabling leading experts in the United States and Eastern Europe to combine complimentary talents and pool research resources in areas at strong mutual interest and competence.

科罗拉多大学博尔德大学米切尔·贝格曼（Mitchell Begelman）博士和华沙哥白尼天文中心的马雷克·西科拉（Marek Sikora）博士之间的美国 - 波兰研究项目的主要目标是提高我们对活跃银河系核的工作的理解。 研究人员将通过研究其假设的天体物理后果来做到这一点，即相对论质子是在类星体和其他活跃的银河核（AGN）中产生的。 他们的工作应产生有关非常高能量伽马射线和中微子通量的定量预测。 对这些颗粒的检测将证明相对论黑龙在AGN中的重要性，并有可能支持它们在形成强类星体风中起关键作用的理论。 结果可能解决了与观察到的BEL（宽发射线）和BAL（宽吸收线）区域的银河系现象有关的几个理论问题。 该项目在阿拉加河外天文学中实现了计划的目标，即通过使美国和东欧的主要专家能够在浓厚的共同利益和能力的领域中结合免费人才和汇总研究资源来推进科学知识。
