Lunch Seminar 2014

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 (, Qi Guo (, Ran Li (  For other questions about the talk (e.g., format of the talk, subscription to the mailing-list), please contact Ms. Shumei Wu (

Lunch for all attendees will be served for free.  However, please note that the price of taking food for free is that you are agreeing to participate by presenting something when asked to do so. You may expect to be asked to summarise a paper once or twice per semester.

If you will come, please order food BEFORE 10:00 am on that day. If you have any visitors who will be attending and who wish to eat lunch, please also order for them.

Lastly, the description of the talk format is here.
