Abstract: We propose that topological order can replace sterile neutrinos as dark matter candidates to cancel the Standard Model global gravitational anomalies. Standard Model (SM) with 15 Weyl fermions per family (lacking the 16th, the sterile right-handed neutrino nuR) suffers from mixed gauge-gravitational anomalies tied to baryon number plus or minus lepton number B+(-)L symmetry. Including nuR per family can cancel these anomalies, but when B+(-)L symmetry is preserved as discrete finite subgroups…

Abstract: How scientists explore the universe, establish new laws of nature, and confront a dazzling array of new questions.  This talk is particularly aimed at students.

Abstract: Welcome to the Indico page of the ORIGINS PhD Days 2025! The PhD workshop will take place at Hotel Alpenrose in Kufstein, Austria from May 14th to 16th. During this event the ORIGINS PhD students can present their work (a presentation of 12+3 min) and exchange ideas to further their research and socialize in a safe environment at the lovely Hotel Alpenrose. Conference costs, lodging, and meals, (excl. additional drinks etc.) will be funded by the ORIGINS Excellence Cluster. Please be…

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: 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: 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…
