The CTAO’s “Physicists On-Call” program brings very high-energy astronomy to you! There is no better way to delve into the intriguing extreme Universe, the CTAO’s innovative technology and its coming scientific achievements than hearing from an expert in the field. The CTAO’s Central Organisation and Consortium members are located in dozens of countries around the world. If you are a member of an education institution (primary, secondary, collegiate or post-graduate levels) or of an astronomical association, you can now request a talk in one of the many languages spoken within our project. Presentations are initially carried out online, but in-person talks could be possible according to the speakers’ availability. Based on the information provided through the request form, the topic will be adapted to the level agreed upon between the speaker and the educator.
