In FY2020-2021, before I abolished the project on September 31st, I have been working on ALMA data to analyze a protoplanetary disk candidate in the Central Molecular Zone around the Galactic Center. The paper has been submitted and referees' feedback has been received. The updated draft is expected to be resubmitted by the end of the year. I joint an astrochemical study of the Sgr B2 region in the Central Molecular Zone, and detected a new organic molecule using ALMA archival data. I was the third author of the paper published by ApJ, and the result is highlighted on the ALMA-J website.I submitted two ALMA Cycle 8 proposals related to the current research topic, and got one Grade A and one Grade B. I will use them to study magnetic field and chemistry in the Central Molecular Zone.

在2020 -2021财年，在我于9月31日取消该项目之前，我一直在研究阿尔马数据，以分析银河系中心周围中央分子区的原行星盘候选者。论文已提交，并已收到审稿人的反馈。更新后的草案预计将在年底前重新提交。我参与了一项对中央分子带Sgr B2区域的天体化学研究，并利用阿尔马档案数据检测到一种新的有机分子。我是ApJ发表的论文的第三作者，结果在ALMA-J网站上突出显示。我提交了两份与当前研究主题相关的阿尔马Cycle 8提案，并获得了一个A级和一个B级。我将用它们来研究中央分子区的磁场和化学。
