Student Project Week October 2024
The 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.

Welcome to our new PI Elisa Pueschel
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
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.

Open house with the mouse
On 3th October, the Faculty of Physics at the Ruhr University Bochum invited children to the Mouse Day. After the physics show, the children experimented in numerous workshops and explored the world of physics. Participants learned about plasmas and their important applications in the plasma workshop, such as coating surfaces. They were able to ignite plasmas, experiment and coat samples using the sputter coater.

Plasma School
The 27th International Plasma School on "Low Temperature Plasma Physics: Basics and Applications," took place from October 5 to October 10, 2024, in Bad Honnef, Germany. The Master Class titled “Plasmas, Liquids, and Nanomaterials,” was held from October 11th to October 12th, 2024. For more information , please visit our website: www.plasma-school.org.

Physical Review Letter on turbulence
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:

Long Night of Astronomy 2024
On Saturday 19.10.2024 the “Long Night of Astronomy” will take place all over Germany.
There will be lots of fun with comets, planets and solar observations at our Campus Observatory!
We will meet at the Audimax of the RUB at 5 pm. The event will last until 10 pm.
Please check this webpage for more information!
We are looking forward to seeing you on Saturday!
Important: The observations only take place in good weather.
You can find further activities during the long night of astronomy here.

We are pleased to invite you to the public lecture “Zwerggalaxien: Zeugen und Treiber der kosmischen Evolution" (in German).
In his talk, Adam Enders will focus on dwarf galaxies and their unique properties, highlighting their crucial role in the evolution of our cosmos. You will discover how these small galaxies play a decisive part in shaping the universe.
When 23.10.24 at 20:00
Where Planetarium Bochum
For registration and further information, please have a look at the Planetarium’s homepage.

Investigating the neighbourhood of galaxies
Our Universe is expanding, and this goes even faster with time. But the cause of that - the mysterious Dark Energy - is still unknown.
To understand these fundamental processes better, is it important to know the distribution of matter in the universe.
An international team, including CRC members Hendrik Hildebrandt and Anna Wittje is carrying out the „Physics of the Accelerating Universe“ Survey (PAU Survey). This survey aims to map the distance and surrounding of 1.8 million galaxies.
The picture shows roughly half of the sample, with the distance colour-coded - revealing nicely the large-scale structures of the Universe.
These data will help to constrain galaxy parameters which are essential for solving the Dark Energy puzzle.
The full RUB press release can be found here (in German).

"Türen auf mit der Maus"
On October 3, it has become a nice tradition that many doors to companies and institutes are opened with the help of the “Sendung mit der Maus” show, giving children an insight into many exciting areas.
Together with the Faculty of Physics and Astronomy and the AIRUB, we once again took part and were able to offer a varied program. Around 80 children between the ages of 4 and 16 spent a fun-filled day at our faculty with experiments on flying rockets, shining stars, delicious physicist ice cream and much more.
More on the "Maus Türöffner Tag" can be found here.

Two PhD Students at Hakone conference
Soad Mohsenimehr and Henrik van Impel (A6) gave presentations on their latest research at the 18th Hakone Conference, which took place in Padua, Italy, from September 1st to 6th, 2024. The event featured numerous insightful presentations dealing with low-temperature plasmas at atmospheric pressure and their applications in plasma chemical processes. One of the highlights of the conference was the active participation of students: 22 of the 56 presentations were given by PhD students, which created a very appealing environment for young researchers. In particular, dielectric barrier discharges were discussed in terms of their efficiency when used with catalysts and the basic physical dynamics of the discharges. Other topics included plasma applications in agriculture and food processing as well as the interaction between plasma and liquid. In addition to the scientific findings, the conference provided an excellent platform for PhD students to network with international participants from 24 countries, promoting collaboration between disciplines.
