AI 中文摘要
我们提议开发一个工作在100 - 350MHz频段的低频甚长基线干涉测量(VLBI)网络,纳入平方公里阵列低频段(SKA-LOW)。SKA-LOW预计在此频段实现极高灵敏度。通过将SKA-LOW与亚太地区其他高灵敏度射电望远镜整合,该网络灵敏度预计比现有甚长基线阵列(VLBA)提高两个数量级。虽已有利用低频VLBI的科学主题提议,但我们特别提倡用现有VLBI站进行天体测量研究以证明该频段的可行性和科学潜力。此外,SKA-LOW与其他射电望远镜结合将实现高保真成像观测,显著提升低频VLBI科学的质量和范围。
英文摘要
We propose the development of a low-frequency Very Long Baseline Interferometry (VLBI) network operating in the 100-350 MHz range, incorporating the Square Kilometre Array Low (SKA-LOW). SKA-LOW is expected to achieve exceptionally high sensitivity within this frequency band. By integrating SKA-LOW with other high-sensitivity radio telescopes located across the Asia-Pacific region, the proposed network is anticipated to deliver up to two orders of magnitude improvement in sensitivity compared to the existing VLBA. While several scientific themes utilizing low-frequency VLBI have already been proposed, we specifically advocate for astrometric studies employing existing VLBI stations to demonstrate the feasibility and scientific potential of this frequency regime. Furthermore, the combination of SKA-LOW with additional radio telescopes will enable high-fidelity imaging observations, significantly enhancing the quality and scope of low-frequency VLBI science.
