银河系超新星遗迹高能观测普查

A Census of High-Energy Observations of Galactic Supernova Remnants

Gilles Ferrand, Samar Safi-Harb

摘要:

我们提出了第一个公共数据库的所有已知的银河系超新星遗迹(SNRs)的高能量观测。在第1节中,我们介绍了这项工作的基本原理,主要是通过研究SNRs中的粒子加速,其目的是将现有的银河系SNRs普查(主要是在无线电波长下进行的)与这些物体在高能量(X射线和伽马射线制度)下不断增长但多样化的观测结果联系起来。在第2节中,我们展示了用户如何使用专用的Web前端(http://www.physics.umanitoba.ca/snr/SNRcat)浏览数据库。在第3节中,我们给出了一些关于我们迄今为止收集到的记录的基本统计数据,这些数据提供了我们目前对银河系SNR的看法的摘要。最后,在第4节中,我们讨论了这项工作的一些可能的扩展。我们相信,这一目录将是有用的观察员和理论家,并及时与无线电/高能信噪比研究的协同作用,以及即将到来的新的高能任务。网站上提供的反馈表将使用户能够提供评论或投入,从而帮助我们不断更新数据库,使其掌握最新的观察结果。

英文摘要:

We present the first public database of high-energy observations of all known Galactic supernova remnants (SNRs). In section 1 we introduce the rationale for this work motivated primarily by studying particle acceleration in SNRs, and which aims at bridging the already existing census of Galactic SNRs (primarily made at radio wavelengths) with the ever-growing but diverse observations of these objects at high-energies (in the X-ray and gamma-ray regimes). In section 2 we show how users can browse the database using a dedicated web front-end (http://www.physics.umanitoba.ca/snr/SNRcat). In section 3 we give some basic statistics about the records we have collected so far, which provides a summary of our current view of Galactic SNRs. Finally, in section 4, we discuss some possible extensions of this work. We believe that this catalogue will be useful to both observers and theorists, and timely with the synergy in radio/high-energy SNR studies as well as the upcoming new high-energy missions. A feedback form provided on the website will allow users to provide comments or input, thus helping us keep the database up-to-date with the latest observations.
