论文摘要
这份白皮书描述了很长的基线干涉法(VLBI)的科学案例,并为欧洲VLBI网络(EVN)的升级路径提供了建议。 EVN是一个分布的长基线无线电干涉阵列,在天文学研究的最前沿运行。最近的结果以及本愿景文档中概述的新科学可能性表明了EVN产生新的令人兴奋的结果的潜力,这将改变我们对宇宙的看法。 EVN与E-Merlin一起提供了一系列基线长度,可以在各种空间尺度上对微弱无线电源进行独特的研究。 在涵盖以下广泛领域的六章中审查了科学案例:宇宙学,星系形成和进化,主动银河核的最内向区域,爆炸性现象和瞬态,恒星和出色的梅尔斯,以银河系,天体的参考框架和空间应用。该文档以确定与其他广播的协同作用以及多频段/多通信器仪器的结论,并为将来的改进提供了建议。附录简要描述了其他无线电VLBI阵列,EVN发展的技术框架以及低于100 GHz的天体物理兴趣的光谱线条。该文档包括非专家的词汇表,最后是缩写词。
This white paper describes the science case for Very Long Baseline Interferometry (VLBI) and provides suggestions towards upgrade paths for the European VLBI Network (EVN). The EVN is a distributed long-baseline radio interferometric array, that operates at the very forefront of astronomical research. Recent results, together with the new science possibilities outlined in this vision document, demonstrate the EVN's potential to generate new and exciting results that will transform our view of the cosmos. Together with e-MERLIN, the EVN provides a range of baseline lengths that permit unique studies of faint radio sources to be made over a wide range of spatial scales. The science cases are reviewed in six chapters that cover the following broad areas: cosmology, galaxy formation and evolution, innermost regions of active galactic nuclei, explosive phenomena and transients, stars and stellar masers in the Milky Way, celestial reference frames and space applications. The document concludes with identifying the synergies with other radio, as well as multi-band/multi-messenger instruments, and provide the recommendations for future improvements. The appendices briefly describe other radio VLBI arrays, the technological framework for EVN developments, and a selection of spectral lines of astrophysical interest below 100 GHz. The document includes a glossary for non-specialists, and a list of acronyms at the end.
