Abstract: The origin and propagation of cosmic rays (CRs) is a multi-disciplinary problem in which plasma (astro)physics plays a major role. Plasma processes are indeed determining how these charged particles are injected and accelerated at their astrophysical sources, as well as the type of turbulence that CRs encounter as they propagate through different Galactic environments; cosmic-ray propagation itself is defined by plasma processes underlying their non-linear interaction with turbulence. More than…

Abstract: A richly illustrated tour of a century of high-energy collisions featuring people, ideas, and stories, free of dense equations and impenetrable jargon.

Abstract: The study of the different flavors of quarks and leptons may answer some of the most interesting questions of particle physics, including explaining why the visible universe is built only of matter, not antimatter and discovering new particles and forces not yet known to us. The Belle and Belle II experiments, located at KEK in Tsukuba, Japan precisely measure flavor phenomena using their large data sets. I will present an accessible overview of the experiments, their measurement techniques, and…

Abstract: 1) The nature of life: what must fine-tuning allow?  2) Physics issues: the emergence of atoms and molecules   3) Cosmological issues: how structure arises, the role of dark matter and dark energy 4) The multiverse option: observational and physical issues 5) Do we need observational evidence? The No Alternatives Argument (NAA) proposes not. But is it convincing?   6) Fine tuning and philosophy: what are the options? How satisfactory are they?   7) Supporting evidence: the…

Abstract: A 1-day workshop will bring together local experts in the field of galactic winds to discuss the latest advancements in understanding the role of outflows in galaxy formation and evolution. Topics will include the mechanisms driving galactic winds, their interaction with the circumgalactic medium, and their impact on star formation, chemical enrichment, and large-scale structures. The event aims to foster collaboration and stimulate discussions on pressing questions in the field, focusing on…

Abstract: Overview Understanding the neutrino is a global scientific priority. The search for neutrinoless double-beta decay is one of the most promising approaches to addressing fundamental questions about this elusive particle. Worldwide efforts are actively driving progress in the quest for this rare phenomenon. The discovery of this decay would have far-reaching consequences in particle physics and cosmology and could answer some of the most fundamental questions in astroparticle physics. …

Abstract: Our understanding of the evolving population of supermassive black holes (SMBHs) beyond the local universe is limited to actively growing SMBHs, where relatively stable accretion of gas is thought to persist over hundreds of millions of years. A growing number of transient phenomena in galaxy nuclei have recently begun to shed new light on SMBH demographics and the physics of gas accretion onto these objects, tracing events where this accretion has drastically intensified, diminished, and/or…

Abstract: The ORIGINS Turbulence day should bring together researcher working on turbulence on different scales. The event will feature presentations from various research projects within our connector, with a special focus on giving early career scientists the opportunity to showcase their work. Depending on the number of registrations, the precise time of the meeting will be adjusted. In the evening after the meeting we plan to have a barbecue to encourage more informal discussions.

Abstract: The study of the dynamic Universe on all astronomical scales allows us to pinpoint the underlying physical processes that not only lead to the formation of stars and planets from the turbulent interstellar medium, but also determine the structure of the Universe on the largest observable scales.  The symposium is organised in honour of Professor Andi Burkert, to celebrate his long career. The symposium highlights the various dynamical processes covered by Andi's work and brings together…

Abstract: In 2025, the HERA workshop series, which is generously supported by the Wilhelm and Else Heraeus Foundation, will carry on with its mission by organizing the next workshop in Pisa, Italy. These workshops serve as a platform for early career scientists to receive training, engage in interactive discussions, conceptualize research projects, broaden their perspectives, and initiate international collaborations. The third workshop in this series is scheduled for the week of September 22nd-26th,…

Abstract: The purpose of the Large Scale Structure Day is to bring together all the people in southern Germany and beyond who are interested in the LSS of the Universe with the aim of fostering fruitful exchanges and collaborations among them. The big question for this year will be the transition from stage 3 to stage 4 surveys. Where do we stand with and what did we learn from stage 3 surveys, and where are we going with and what are the challenges for stage 4 surveys? Some topics that will be…
