Lunch Seminar 2013

2012 | 2013 | 2014 | 2015

The lunch talk at Galaxy and Cosmology (G&C) Division of NAOC is held on Wednesdays (except holidays), starting from 12:00pm at A508. It is an informal seminar, discussing the recent progress on almost all the aspects of the astronomy and astrophysics, covering from the small scale structure and its dynamics of the star and galaxy, to the large scale of the Universe. All the G&C members are encouraged to attend, and the other NAOC members are also welcome. We also welcome the volunteer as a speaker volunteer, especially from other institutes. In case you are willing to do the talk, please feel free to contact either Dr. Lijun Gou (, or Dr. Stephen Justham ( For other questions about the talk (e.g., format of the talk, subscription to the mailing-list), please contact Ms. Jie Ma (

The (normal/vegetarian) lunch box will be served for free for the attendees on request, but one will have to ORDER the lunch before 10:00am on the day the talk is happening, following the link provided in the email alert.

Lastly, the description of the talk format is here.
