ITP / ITA Journal Club

* This page refers to Journal Club meetings up to the Winter Semester 2016/17. *

Tuesday, Phil 12, Room 056

13:00 - 15:00

The ITP/ITA Journal Club is a joint Journal Club from the Cosmology groups of ITA and ITP.

Every two weeks, some recent papers in the literature are presented by our members and afterwards we have a short discussion session.

We use the Heidelberg VoxCharta platform in order to suggest interesting literature and list the papers to be presented in the next meeting.

In VoxCharta you can also find our previously discussed papers.

Here you can access our Google Calendar to check future dates and the name of the speakers.
