Dear colleagues, we would like to draw your attention to IFA's Ole Rømer Colloquium Series for the upcoming semesters 2019/20. Making a dedicated effort to attract more students, the colloquium also aims at displaying the breadth of IFA's research to our young as well as future scientists. To maintain such a venue we would like to call on all of you for your help in finding excellent speakers for the Ole Rømer Colloquium. Please, submit your proposals via a short email to Grete Flarup (flarup@phys.au.dk), including the speaker's name, affiliation and keywords for the prospective topic of the talk. Above all, the priority is, of course, to find engaging speakers with an ability to deliver captivating presentations that will likely draw broad interest within our Department. The colloquium will take place Wednesdays 14:00, and free spots are currently available starting from October 2019 until June 2020. Thank you very much and best regards, Jill Miwa Thomas Tauris Thomas Pohl Ulrik I. Uggerhøj
