HEA: Lunch Talks
 
 Previous talks (2004-present)
Last modified: 2008-10-14 14:51:57

The High Energy Astrophysics Division of the Harvard-Smithsonian Center for Astrophysics hosts a weekly series of informal lunch talks on Wednesdays at 12:30pm. The purpose of the talks is to stimulate discussion on a wide variety of topics related to High Energy Astrophysics and to broaden the horizons of staff and visitors. Talks will be in Pratt at 60 Garden St. Talks that take place at a different location and/or date/time will be marked in red text.

We encourage all HEAD members to be on the lookout for interesting potential speakers and to communicate their ideas to the coordinators Anca Constantin (aconstantin@cfa) and Gijs Roelofs (groelofs@cfa).
