项目摘要
AST 0307365PI: GonthierUntil now the Compton Gamma-Ray Observatory has detected pulsed gamma-ray emission from about 10 isolated pulsars, and more than a dozen X-ray pulsars have been detected by other satellites. Simulations of these emission processes in neutron star magnetospheres have not been able to pin down the location of the acceleration and emission regions whether the acceleration of particles occurs near the neutron star surface (polar cap models) or many stellar radii from the surface near the light cylinder (outer gap models). The team will improve current simulations by introducing realistic luminosities and geometries of radio and gamma-ray beams for both the polar cap and outer gap models. These calculations will put the polar cap and outer gap models on the same footing within the same calculation normalized by the comparison of the simulated radio pulsars with those observed by a selected group of radio surveys. The team will investigate further discriminating signatures by studying the correlations between the radio profiles and the gamma-ray profiles. There is growing evidence for the existence of a new class of isolated neutron stars with ultra-strong magnetic fields that includes soft gamma-ray repeaters (SGRs) in which photon splitting and Compton scattering play a significant role in the magnetospheric physics. As in the previously accomplished work for Compton scattering in the polar cap model, the team will develop magnetic Compton scattering required in these near or supra critical magnetic fields applicable to the SGR environments. These projects have broad impacts primarily on the education of undergraduate students by providing an environment and challenging topics that lead to the enhancement of their knowledge and skills. The PI will take students for a month to Goddard Space Flight Center where the undergraduates will interact with NASA scientists discussing their findings as well as attending talks given in a wide variety of areas of investigation. The students are respected as fellow colleagues in the pursuit of the project and are encouraged to excel. The experience instills in the students the confidence in their quest and encourages them to train and discipline themselves. The students also gain oral and presentation skills as they prepare and present a poster at the end of their summer experience, later presented in a yearly research symposium at Hope College.
到目前为止,康普顿伽玛射线天文台已经探测到大约10颗孤立脉冲星的脉冲伽玛射线发射,其他卫星已经探测到十多颗x射线脉冲星。对中子星磁球中这些发射过程的模拟还不能确定加速和发射区域的位置,无论粒子的加速是发生在中子星表面附近(极帽模型)还是发生在离光柱表面附近的许多恒星半径处(外间隙模型)。该团队将通过为极帽和外隙模型引入真实的亮度和射电和伽马射线光束的几何形状来改进当前的模拟。通过将模拟的射电脉冲星与一组选定的射电巡天观测到的脉冲星进行比较,这些计算将使极帽和外层间隙模型在相同的计算中处于相同的基础上。研究小组将通过研究射电谱图和伽马射线谱图之间的相关性来进一步研究鉴别特征。越来越多的证据表明,存在一类具有超强磁场的新型孤立中子星,其中包括软伽玛射线中继器(sgr),其中光子分裂和康普顿散射在磁层物理中起着重要作用。正如之前在极帽模型中完成的康普顿散射工作一样,该团队将开发适用于SGR环境的近临界或超临界磁场所需的磁性康普顿散射。这些项目通过提供一个环境和具有挑战性的主题来提高他们的知识和技能,主要对本科生的教育产生广泛的影响。PI将带学生们去戈达德太空飞行中心一个月,在那里,本科生们将与美国宇航局的科学家们互动,讨论他们的发现,并参加各种调查领域的讲座。在追求项目的过程中,学生们被尊重为同事,并被鼓励超越。这种经历让学生们对自己的追求充满信心,并鼓励他们训练和约束自己。在暑期实习结束时,学生们准备并展示一幅海报,随后在霍普学院的年度研究研讨会上展示,这也提高了学生们的口语和演讲技巧。
