From underground experiments on earth to virtual laboratories in the sky - this episode of FNWI College Tour will focus on energy in our universe. What can we learn from/about the accelerator at CERN, black holes and the Big Bang when it comes to energy research? With: Sera Markoff and David Berge.
Subatomic particle interactions are at the heart of most physical processes in the Universe, and energetic collisions in particular are at the bounds of what we can study here on Earth. We thus use objects in space as another form of laboratory, which together with our human-made experiments can probe the range of relevant interactions.
Through a tour of our state-of-the-art research, we will (among other things) address the following questions: How are particle collisions in the most powerful human-made accelerator at CERN related to the beginning of the universe or near black holes? What are the most powerful engines in the Universe and what powers them? How can a single particle receive enough kinetic energy to equal that of a moving tennis ball? And how do you use the whole atmosphere like a telescope? Can you actually see the event horizon of a black hole?
NB. This lecture will be held in English.
Sera Markoff (USA) is an astrophysicist and UHD at the UvA. She is involved in observational projects from the radio through gamma-ray frequencies, and leads a research group to develop models for how black holes are powered via the gravitational capture of material, eventually creating relativistic particles and light.
David Berge is a lecturer at the Faculty of Science of the UvA, at both the astronomical institute Anton Pannekoek (API) and the high-energy physics institute (IHEF) and Nikhef. He is working at the interface of astrophysics and high-energy particle physics. At API, he is involved in telescope projects to measure very high energy photons from space. At IHEF/Nikhef he is a member of the ATLAS experiment at CERN searching for dark matter particles.
