Global holographic VLBI capability for the Alqonquin Radio Observatory

加拿大曾经在射电天文学和VLBI的发展方面处于世界领先地位，VLBI是一种先进的射电技术，它将分散的望远镜组合成一个仪器，大于其各部分的总和。由Thoth Technologies Inc.运营的阿尔冈昆射电观测站(ARO)仍有大量基础设施。我们建议发展ARO能力，使其再次成为世界领先的VLBI节点，使Thoth能够在科学、技术和经济上进行竞争。科学上，我们将开发全息VLBI新技术，将VLBI的分辨率与星际闪烁的分辨率结合起来，以获得更高的分辨率。最近对脉冲星的VLBI分析表明，亚纳弧秒位置探测是可能实现的。这项提议将推进VLBI的前沿。

Canada was once world leader in radio astronomy and the development of VLBI, an advanced radio technique which combines widely separated telescopes into a single instrument, greater than the sum of its parts. Substantial infrastructure still remains at the Algonquin Radio Observatory (ARO), operated by Thoth Technologies Inc. We propose to develop ARO capability to again become a world leading VLBI node, enabling Thoth to compete scientifically, technically and economically. Scientifically, we will be developing the new technique of holographic VLBI, which combines the resolution of VLBI with that of interstellar scintillation to obtain increased resolution. Recent VLBI analysis of pulsars indicates that sub nano-arcsecond position detection may be achievable. This proposal will advance the VLBI frontier.
