In memoriam: Maolin Zhang
19 January 2019
We are grief-stricken that our PhD student Maolin Zhang passed away during the early morning of January 17th 2019. He died during a terrible fire that took place at his house in Hillegom.
Maolin was born on July 25th 1991 and grew up in the countryside near Yangtang Village, Shuangqiao Town, Qidong County, Hunan Province, China. After graduating from secondary school, he was admitted to the prestigious Tsinghua University in Beijing. He obtained a Masters degree in Engineering from the Department of Engineering Physics there in July 2016. His Masters thesis was entitled Interferometric imaging and data processing.
During the summer of 2014 he participated in a student program at the Netherlands Institute for Radio Astronomy (ASTRON) at Dwingeloo, the Netherlands. Supervised by Tom Oosterloo he used observations taken by the Westerbork radio telescope to study the distribution of hydrogen gas in galaxies. His exposure to radio astronomy motivated Maolin to apply for a scholarship from the Chinese Scholarship Council (CSC) to pursue a PhD in radio astronomy at Leiden Observatory. After being awarded this prestigious scholarship, Maolin travelled to Leiden in mid-2017 and started on a PhD project supervised by Prof. Huub Röttgering that involved observations of the distant Universe by the LOFAR radio telescope. During his first year at Leiden Maolins research concentrated on the analysis of LOFAR results on the formation and evolution of massive galaxies and black holes. He reduced data for a sample of radio sources whose properties indicate that they are located at extremely large distances. The results provided an important contribution to a paper that was led by Aayush Saxena, another Leiden PhD student.
During his second year, Maolin helped develop a new Bayesian technique to select large and well-defined samples of quasars from a multi-wavelength combination of data from recent surveys from optical telescopes and radio surveys from the LOFAR telescope. Working closely with Ken Duncan, Jonah Wagenveld and his promotor Huub Röttgering, he was well on his way to publishing his first paper.
Maolin was an extremely intelligent, hardworking and dedicated student with a passion for astronomy. He was eager to learn, always seeking to develop his skills, knowledge and experience further. We know Maolin as friendly, always smiling, modest and grateful for his chances in life. He had many interests outside of astronomy, including table tennis, tennis, Chinese chess, cooking and fishing. As a board member of the Leiden Science China community (LSC), he was an active member of the Chinese community at Leiden University. In his enthusiastic, diligent, and helpful way he was responsible for promoting various events organized by the LSC. He designed the nice logo of the LSC.
The loss of Maolin leaves a deep hole at the heart of our institute. It has been a privilege to know Maolin and to work with him, and it is hard to realise that he is not among us any more. Maolins journey to unravel the mysteries of the universe has come to a shocking and unexpected end. We will always remember Maolin as a bright star in our universe.
In memory of Maolin, we have created a special place in the Oort building, (Oortkamer, room 531).
It offers a place to think about him, to leave a message in a condolence book and to share your grief with colleagues, students and friends.
There was a home for you
in an exciting, cold and exotic place
with statistics and machines
dissecting the seemingly lifeless universe
probing galaxies
so far out
You
a living bubble surrounded by alien words
your lampoon brightening the ocean
preying on fish
fish and discovery
discovery and science
warming all bubbles in sight
the communal hot tub of life
a strange ride
encounter and adventure on your way
somehow something popped your bubble
way too soon
how can we grapple with something
so far out
The path of least resistance is straight up
from the place you first opened your eyes
from the place you first gazed up
some travel farther than others
explore further than others
so far out
You are one of them
You are one of us
We miss you Maolin

茂林，于1991年7月25日出生，在中国湖南省启东县双桥镇杨塘村附近的农村长大。从中学毕业后，他被录取到着名的北京清华大学。他于2016年7月在那里获得了工程物理系的工程硕士学位。他的硕士论文题为“干涉成像和数据处理”。
2014年夏天，他参加了荷兰Dwingeloo的荷兰射电天文学研究所（ASTRON）的学生项目。在Tom Oosterloo的监督下，他利用Westerbork射电望远镜拍摄的观测资料来研究星系中氢气的分布。他接触射电天文学，促使茂林申请中国奖学金理事会（CSC）的奖学金，以便在莱顿天文台攻读射电天文学博士学位。在获得这一着名奖学金后，茂林于2017年中期前往莱顿，开始了由HuubRöttgering教授监督的博士项目，该项目涉及LOFAR射电望远镜对遥远宇宙的观测。在莱顿茂林的第一年，他的研究主要集中在对大质量星系和黑洞的形成和演化的LOFAR结果进行分析。他减少了无线电源样本的数据，这些无线电源的属性表明它们位于极远的距离。结果为另一位Leiden博士生Aayush Saxena领导的论文做出了重要贡献。
在他的第二年，茂林帮助开发了一种新的贝叶斯技术，从最近的光学望远镜调查和LOFAR望远镜的无线电测量数据的多波长组合中选择大型和明确定义的类星体样本。与Ken Duncan，Jonah Wagenveld及其发起人HuubRöttgering密切合作，他正在出版他的第一篇论文。
茂林是一位非常聪明，勤奋，敬业的学生，对天文学充满热情。他渴望学习，总是寻求进一步发展自己的技能，知识和经验。我们知道茂林是友好的，总是微笑，谦虚和感激他的人生机会。他在天文学之外有许多兴趣，包括乒乓球，网球，中国象棋，烹饪和钓鱼。作为莱顿科学中国社区（LSC）的董事会成员，他是莱顿大学华人社区的积极成员。他热情，勤奋，乐于助人，负责推动LSC组织的各种活动。他设计了LSC的漂亮标志。
失去茂林在我们学院的中心留下了深深的空洞。能够认识茂林并与他合作是一种荣幸，很难意识到他不再是我们中间的人。茂林的解开宇宙奥秘的旅程已经到了令人震惊和意想不到的结局。我们将永远铭记茂林是我们大学中的一颗璀璨明星。
2019年1月25日，下午4点到7点。荷兰-莱顿大学在学术楼的中心，举办了纪念张茂林的活动，
后荷兰-莱特大学考虑到张茂林的父母是湖南省启东县双桥镇杨塘村附近的农村的村民，于是设立了一个4万5欧元的给张茂林父母的退休计划。
现在已经完成募捐超过了6万欧元。
希望茂林，在天之灵，安息。
轩辕法侠提醒大家，出国留学生在国外一定要好好保护自己，同时不要被国外的犯罪份子所利用。
