Did you know about the prestigious NAC poster prize? This is a tradition that goes back almost 40 years. If you take notice of the following tips you might just win it!

  • The purpose of the poster is foremost to catch the attention from the distance, keep that attention alive for at least one minute and make the reader wanting to talk to you.
  • Specify motivation, main question, method and result of your study. Make sure these are quickly understandable to a broad audience.
  • Present a straightforward logical flow through the poster, to avoid the reader asking for directions. Arrows can do the trick.
  • Use appealing color schemes without overdoing it.
  • Be concise. Try to convey the message graphically (2 or 3 simple plots plus perhaps 1 or 2 cartoons/artist impressions) with a minimum amount of text. Be creative, but not at the expense of science.
  • Use of equations/jargon/acronyms with explanation and in moderation!
  • Include a picture of yourself, to help people find you for a chat.
  • QR codes with links to additional material (e.g., paper, website, and pdf of poster) are a bonus.


  • Please upload your slides prior to the meeting.
  • Presentations can be shown in PowerPoint (version 16.12), Keynote (version 8.0.1), and Adobe Reader (version 18.011), all running on macOS High Sierra (version 10.13.4). In addition the VLC media player (version 2.2.8) is available.
  • The screen has a 4:3 ratio. The beamer supports 16:9 and projection fits the screen.

Maybe the following helps preparing your talk:

  • Provide an intro. Astrophysics covers many specialties and you can assume that an arbitrary astrophysicist is unfamiliar with the specifics of your field and methodology.
  • Keep the total amount of information limited. An audience can cope with only a few results, explanations, breakthroughs or topics. Even if you have achieved great results in the past year, do not be tempted to present “everything”.
  • Keep the amount of information per slide limited.
  • Keep the total amount of slides limited. A rule of the thumb is: one to two minutes per slide.
  • Pay special attention to figures and diagrams. Never ever forget to explain what is on the axes (physical quantity, dimensions). Never assume that the audience is familiar with “standard” diagrams . The audience needs your help and sufficient time to absorb and appreciate a figure.
  • Put a great deal of effort in remaining within the allocated time, 15 minutes, to allow 3-5 minutes for questions and discussion.
  • Put at least as much effort in your oral as your visual presentation.
  • Strong suggestion: rehearse the talk, preferably with an audience (containing if possible a person working in a different astrophysics field).
