Our scientist Rainer Grauer was involved in the development of a new approach to describe turbulence mathematically, together with his student Sumeja Bureković and long-term collaborator Tobias Schäfer (City University of New York).
In particular, irregular fluctuations, so-called intermittency, which cannot be described with a normal Gaussian distribution, are addressed.
They developed an approach using instantons - represent the probabilities of turbulence as a spatio-temporal path integral. This method allows for the first time to describe and calculate isolated and localized fluctuations, which is a major step in solving one of the big open questions in classical physics.

We are delighted that Dr. Elisa Pueschel (AIRUB) has joined our CRC as a new PI!
Elisa's research focuses on very-high-energy gamma-ray astronomy, including gamma-ray cosmology, blazar science, and the search for astrophysical dark matter. She is particularly interested in heavy dark matter above 100 TeV. She will use current and future generation gamma-ray instruments - including the Dark100 array, which her group focuses on - to probe this interesting dark matter phase space.

About 300 astronomy enthusiasts came to the RUB on Saturday evening (19.10.24) to explore with us and our amateur astronomer colleagues from Ad Astra the wonders of the night sky:
watch comet Comet C/2023 A3 (Tsuchinshan-ATLAS),
investigate Saturn and the moon with optical telescopes,
and make first observations with the radio telescope of the new Campus Observatory.
