标题： Latest developments in wide-field VLBI

摘要： 甚长基线干涉测量（VLBI）将分布在数千公里的望远镜信号结合起来，以提供一些最高角分辨率的天体物理现象图像。 由于计算成本，典型的VLBI观测通常仅限于一个目标和每次指向的小（几角秒）视场。 宽视场VLBI技术的出现是为了实现对多个源的定位，并已在提供活动星系核、星际介质、超新星、引力透镜等的新见解方面取得了成功。 然而，该技术目前仅在少数实验中使用，限制了VLBI观测的科学潜力。 在本次会议论文中，我们概述了宽视场VLBI的新发展，包括端到端的相关性和校准工作流程、分布式相关性以及新的校准程序。 这些发展旨在使宽视场VLBI成为所有主要VLBI阵列的标准观测模式。 显示英文摘要

摘要： Very Long Baseline Interferometry (VLBI) combines the signals of telescopes distributed across thousands of kilometres to provide some of the highest angular resolution images of astrophysical phenomena. Due to computational expense, typical VLBI observations are restricted to a single target and a small (few arcseconds) field-of-view per pointing. The technique of wide-field VLBI was born to enable the targeting of multiple sources and has been successful in providing new insights into Active Galactic Nuclei, the interstellar medium, supernovae, gravitational lenses and much more. However, this technique is still only employed in a few experiments, restricting the scientific potential of VLBI observations. In this conference proceeding, we outline new developments in wide-field VLBI, including an end-to-end correlation and calibration workflow, distributed correlation, and new calibration routines. These developments aim to enable wide-field VLBI to be a standard observing mode on all major VLBI arrays.
