高能天体物理学与下一代射电天文学设施

High energy astrophysics with the next generation of radio astronomy facilities

Rob Fender

摘要:

高能天体物理学很好地利用了高能(X射线、伽马射线)和射电观测的结合,揭示了爆发、吸积、粒子加速和对局部环境介质的动力反馈之间的联系。在微类星体领域,这种联系尤其重要。然而,射电天文学在过去的25年里一直依赖于基本相同的设施,而高能天体物理学,特别是天基研究,有一系列更新和更强大的任务。在接下来的15年里,这种不平衡将得到纠正,一系列新的无线电设施将在2020年代进入平方公里阵列(SKA)。在这篇简短的评论中,我将总结射电天文学的未来前景,并重点介绍可能是未来十年内建造的最令人兴奋的新设施,低频阵列LOFAR及其在高能天体物理学中的应用。

英文摘要:

High energy astrophysics has made good use of combined high energy (X-ray, gamma-ray) and radio observations to uncover connections between outbursts, accretion, particle acceleration and kinetic feedback to the local ambient medium. In the field of microquasars the connections have been particularly important. However, radio astronomy has been relying on essentially the same facilities for the past ~25 years, whereas high-energy astrophysics, in particular space-based research, has had a series of newer and more powerful missions. In the next fifteen years this imbalance is set to be redressed, with a whole familiy of new radio facilities under development en route to the Square Kilometre Array (SKA) in the 2020s. In this brief review I will summarize these future prospects for radio astronomy, and focus on possibly the most exciting of the new facilities to be built in the next decade, the Low Frequency Array LOFAR, and its uses in high energy astrophysics.
