Ingo Allekotte is an Argentinian physicist who is currently the Project Manager of the Pierre Auger Cosmic Ray Observatory, the world’s largest cosmic ray observatory at approximately 3,000 square kilometers in area. He is also an Associate Professor at the Balseiro Institute in Bariloche, within beautiful Patagonia, and a researcher at the National Atomic Energy Commision of Argentina (CNEA).

In our Interdialogue, we spoke about Cosmic Rays – what they are, the fascinating decades-long history of their detections, the risks that they pose for space travel, and the intersection between cosmic ray astrophysics, particle physics and even cosmology. 

We then spoke more specifically about the Pierre Auger Cosmic Ray Observatory and how this interdisciplinary “Big Science” project in Argentina, which incorporates hundreds of scientists from 17 different countries, came to be. Ingo explained some of the exciting discoveries made so far of Ultra High Energy Cosmic Rays (UHECRs), and how they have conclusively demonstrated extragalactic origins. We also spoke about future exciting research objectives, parallel lines of research and Multi-Messenger astronomy.

We concluded our conversation by focusing on science advocacy and the wide-ranging social value of large scientific collaborations like Pierre Auger, while also touching on the importance of maintaining balance and perspective in life by frequently connecting with nature, family and friends.
