Interview with Julia Tjus in "AufRuhr"

06.12.2024

Our speaker Julia Tjus was recently interviewed for the magazine “Aufruhr” by the Mercator Foundation.
She had the opportunity to talk about her research, with a particular focus on cosmic rays. Furthermore, she had the chance to share insights about her scientific career and provided helpful tips for young scientists.

The full interview (in German) can be found here.

Student Project Week October 2024

07.11.2024

SFB1491 was a partner once again for the Student Project Week at the Faculty of Physics and Astronomy of RUB in October 2024!

By that, we are contributing to the effort of inspiring and engaging young people with the fascinating world of physics through hands-on experiences.
The kids experienced an exciting week investigating a broad range of physical effects, from gold coating with plasmas and uncovering the true colors of stars, to learning how ultrasound and X-rays help us see inside the human body.

More information on the program can be found here.

Physical Review Letter on turbulence

28.10.2024

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.

The full publication can be found here:

Welcome to our new PI Elisa Pueschel

24.10.2024

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.

Long Night of Astronomy - Impressions

23.10.2024

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.
