LBA observations for project V596 semester 2021APRS

We have discovered over 20 multiply-imaged lensed quasars (QSOs) using data from the Gaia mission. These candidates have been confirmed using spectroscopy obtained using the ESO/NTT, Gemini-South, Palomar Hale and Keck-I telescopes. We plan to carry out a high-resolution radio survey of these lensed QSOs using Very Long Baseline Interferometry, which will enable us to constrain mass models of the lensing galaxies and make cosmological inferences.

我们基于盖亚（Gaia）任务的观测数据，发现了超过20个多重成像引力透镜类星体（QSO）候选体。该批候选体已通过欧洲南方天文台/新技术望远镜（ESO/NTT）、南双子座望远镜（Gemini-South）、帕洛玛海尔望远镜（Palomar Hale）以及凯克-I望远镜（Keck-I）获取的光谱数据完成确认。我们计划采用甚长基线干涉测量（Very Long Baseline Interferometry）技术对这批透镜类星体开展高分辨率射电巡天观测，借此约束透镜星系的质量模型并开展宇宙学推断。
