Astrophysics Seminars

We hold weekly journal-club meetings every Wednesday at 1:00pm. The format of the meetings, which take place in the 2nd floor seminar room of the Physics Bldg, is rather informal and it ranges from open discussions to presentations by members of the group or visitors.

If you are interested to lead one of these meetings or give a seminar with your recent results, or you would simply like to visit us, please contact Prof. Vasiliki Pavlidou.

A list of recent and upcoming seminars, as well as past talks, is presented in the following table:
