Sonderforschungsbereich bewilligt
DFG fördert die Forschung im RAPP Center mit ca. 11 Millionen Euro zur Untersuchung des Wechselspiels der kosmischen Materie
Am nächtlichen Sternenhimmel sehen wir mit dem bloßen Auge Jahr für Jahr die gleichen Konstellationen, so dass der Eindruck entstehen könnte, es handele sich um ein statisches Konstrukt – ein Gedanke, der sich über Jahrhunderte hielt, bevor es Anfang des 20. Jahrhunderts gelang nachzuweisen, dass das Universum ein dynamisches System ist, das mit einem „großen Knall“ entstanden ist und sich immer weiter ausdehnt.
Auch auf kleineren Skalen ist die Dynamik hoch, Sterne entstehen und vergehen in mächtigen Supernovaexplosionen und beeinflussen so die Dynamik der Galaxien, in denen sie beherbergt sind. Durch die Explosionen entstehen Wolken von Teilchen oder aus Plasma, die mit kosmischen Magnetfeldern wechselwirken. Das Wechselspiel der kosmischen Materie, das diese Prozesse antreibt, ist Leitthema des Sonderforschungsbereichs (SFBs) 1491.

Understanding the theory of particles in plasmas
On Monday, January 22nd, scientists meet at RUB for the yearly meeting "Plasma and Particle Theory Day" to discuss the theory of particles in plasmas. Understanding the collective behavior of ionized particles is in the focus of research. A particular challenge is to understand how physical collisions of particles and the interactions between ions and electromagnetic fields are included in the various equations to describe the systems. In astrophysics, often these equations are dominated by the interaction of particles with electromagnetic waves. This is the research focus of the Collaborative Research Center SFB1491, "Cosmic Interacting Matters - From Source to Signal", centered at RUB. The research department of Plasmas with Complex Interactions also hosts SFB1316, "Transient Atmospheric Plasmas: From Plasmas to Liquids to Solids". Here, non equilibrium processes in atmopsheric plasmas for species conversion are the topic of research. Compared to astrophysical plasmas, these atmopsheric plasmas are very dense and physical collisions dominate the equations. It is the goal of the Plasma and Particle Theory day to move toward exploring the region in which both terms play a significant role. This is for instance the case in molecular clouds in the Milky way, in which the degree of ionization is as low as ~30% and naturally, collisions become important in the description. Another example is the physics of lightning that can be tested in the plasma lab and for which a briding theory is needed to understand the physics of atmospheric lightning. Once the particle interactions become inelastic, i.e at high energies or at extreme densities like they exist in neutron stars, the classical description needs to be replaced by the quantum mechanical one. Scientists therefore discuss the different methods, how synergies can be build and what the next steps are to build a consistent framework to combine classical and quantum-mechanical interactions.

We mourn the loss of our founding member Bernhard Spaan
The founding and the development of the RAPP Center would not have been
the same without him. We will miss him deeply. An obituary
We mourn the loss of Prof. Maxim Polyakov
It is with great sadness that we have learned about the death of our RAPP-PI and college from the Institute of Theoretical Physics at RUB, Maxim Polyakov, who passed away unexpectedly on August 25, 2021
at the age of 55. He will be sorely missed.

PUNCH4NFDI approved
The interdisciplinary consortium "PUNCH4NFDI" will start its work in fall. "PUNCH" stands for "Particles, Universe, NuClei & Hadrons", as the consortium consists of scientists from particle-, astroparticle-, hadron-, nuclear-, and astrophysics. It is coordinated by DESY. The RAPP Center is actively involved in this large-scale effort, with Professors Johannes Albrecht, Kevin Kröninger and Bernhard Spaan from TU Dortmund as applicants, and Professors Hendrik Hildebrandt, Julia Tjus, and Ulrich Wiedner as participants. The insights gained from this interdisciplinary consortium will boost the developments to create a data science platform that serves the entire community. Technically, the platform will consist of a data lake with storage and cloud computing systems, a data transformation layer allowing the analysis of the data, and a user-friendly interface and data portal.

Anna Franckowiak accepts offer for full professorship in Multiwavelength Astronomy
The PIs of the RAPP Center welcome their newest member Anna Franckowiak, who will start as a full professor, taking over the chair "Multiwavelength Astronomy" in October 2020. She will work on the connection of optical, gamma-ray and neutrino emission from Galactic and extragalactic sources and thus contribute in many ways to answering our leading questions. Anna Franckowiak works within the IceCube, Fermi Collaborations and Zwicky Transient Facility (ZTF) Collaborations. She will, when joining Bochum, also extend and shape the Bochum CTA group.
Welcome, Anna!
