Dr. Ke Wang - ESO fellow - Astronomer

Dr. Ke Wang

ESO Fellow	Welcome to my home page! I am a postdoctral fellow at the European Southern Observatory (ESO) Garching Headquarters in Germany. I study the formation of high-mass stars by observing their parent molecular clouds at high angular resolution, using submm/mm/cm interferometers including ALMA, SMA, VLA, CARMA, plus space- and ground-based single dish telescopes including Herschel, IRAM 30m, GBT, APEX, CSO, and KOSMA. I spend 25% of my working time at the European ALMA Regional Center (EU ARC) for my functional work. I enjoy serving as an astronomer on duty (AoD), contact scientist (CS), and data analyst (QA2) at the EU ARC, which means I visit the ALMA site in Chile regularly, communicate with ALMA observers about updates of their observing projects, reduce fresh ALMA data right after observations, and make data products deliverable to PIs.

Public Outreach

I am enthusiastic to tell the general public about the beauty of our Universe and to share fresh, exciting research results of my own. My wife, Dr. Xiaojin An is always my first listener and reader.

I am lucky to have my recent research highlighted to the general public, by Harvard CfA and Royal Astronomical Society of UK, among many other medias word wide.
I have translated a National Geographic Kids popular science book "Super Stars" into Chinese (original author: David A. Aguilar, Harvard CfA). The book is available on Amazon, Taobao, JD, and many other book stores online and offline.
On October 30, 2006, merely one year after my first taste of astronomy, I was invited to give a public talk to 3,000 freshmen at BIT, sharing my view on developing a career as a professional astronomer.

Spare Time

When I am not doing astronomy, I love cooking, skiing, running, and writting (basically food, sports, and sort of literature :-). From 2003 to 2008 I have run the Beijing Marathon yearly, achieved my personal record 3h32m29s in 2006. Since 2013 I started to participate in the Garchinger Runde, exploring the lovely town we live in. In winter 2013/14, I learned skiing and immediately fell in love with the Alps.
