Welcome to MPIA Galaxy Coffee Wiki!
Galaxy Coffee is the informal seminar of the "Galaxies & Cosmology" Department at the MPIA. It is held each Thursday every week at 11:00 am on the third floor at the MPIA.
Currently, we run Galaxy Coffee in hybrid mode in the auditorium/Hörsaal.
If you would like to participate via zoom, please contact the organisers for the zoom link.
Please contact any of the organizers if you would like to volunteer for the free slots available:
- Nadine Neumayer (neumayer@mpia.de)
- Guillaume Guiglion (guiglion@mpia.de)
- Francesco Chiti Tegli (frchiti@mpia.de)
Galaxy Coffee rules:
- keep the talk brief - as a guideline, focus on one punchline.
- make sure to introduce the topic for the "general" audience, i.e. students and people not working in the field.
- we encourage black board presentations, (few) slides are also welcome
- talk time: 10 - 15 minutes.
- discussion time: 5 - 10 minutes (during or after the talk).
- total time per slot must not exceed 25 minutes.
- including some buffer for announcements and general discussions ('I always wondered if / how / why XYZ works' et al.), total Galaxy Coffee time is ~ 60 minutes.
