We are delighted to announce this year's YRC Schöntal Discussion Workshop on Dynamical Systems, which will take place from the 25th to the 28th of August at the quaint and charming Schöntal Abbey.
The aim of the workshop is to provide an opportunity for early-career scientists to gather and discuss topics that go beyond the standard mathematics and physics curriculum, and to approach different subjects from their respective fields of research. The goal is to encourage interdisciplinary scientific exchange between the various areas of the STRUCTURES Cluster.
This year, the overarching topic of Dynamical Systems will be the protagonist. As a key concept in many physical, mathematical, computational and biological applications, we expect it to foster collaboration across different fields and spark conversations that may lead to innovative and creative ideas and applications. The workshop will guide participants through the fundamentals of dynamical systems, including the distinction between continuous and discrete time systems, core concepts such as stability, chaos, and bifurcation theories, and modern applications ranging from training algorithms to recurrent neural networks (RNNs).
This year's invited experts are Dr. Zahra Monfared and Prof. Dr. Tim Laux.

We are delighted to announce that our member Fred Hamprecht, head of the Scientific AI lab at the Interdisciplinary Center for Scientific Computing (IWR) and principal investigator of STRUCTURES, has been awarded one of the European Research Council's prestigious ERC Advanced Grants.
The grant, endowed with € 2.5 million in funding over five years, will support his project Learning Orbital-Free Density Functional Theory (LearningOFDFT). The aim of this project is to develop new methods for the precise and stable calculation of molecular energies based on electron densities, using what is called an orbital-free approach.
Orbital-free approaches provide a major simplification of the quantum-mechanical calculations required to study molecular systems. Understanding molecular structure and reactivity requires precise calculations of molecular energies. Traditionally, this relied on a wave-function description, which depends on the position of every electron in space. While highly accurate, this becomes computationally demanding as molecular systems grow in size and complexity. In 1964, Walter Kohn created a formalism that promised to eliminate the need to account for every single electron's position, instead requiring only the average density of electrons in the space. A formal proof of this claim earned Walter Kohn the Nobel Prize in 1998. Yet, a central challenge remains unsolved: an explicit formula for the kinetic energy functional, the central object of the theory, has remained unknown to this day.
Originally started as an Exploratory Project of STRUCTURES, Fred Hamprecht and his collaborators, notably Roman Remme, pioneered a machine learning method to solve this long-standing problem by learning the mapping from electron density to molecular energy – using physics-inspired AI methods. This work has since developed into a new research line of the cluster. Through close interdisciplinary cooperation with chemists and physicists, it was possible to create the STRUCTURES-25 method, which obtained both chemically precise energies relative to the reference and stable, practical optimization of electron density.
Building on this success, Prof Hamprecht and his team will use the ERC funding to develop fast and precise predictions for increasingly complex systems – thereby contributing to solving the decades-old challenge of finding an orbital-free density functional. If successful, this research promises to open new opportunities for applied research, from the analysis of biomolecular reactions to the development of environmentally friendly materials.

Researchers from across mathematics, astrodynamics, industry, and government gathered at the University of Surrey from 8–11 June 2026 for Geometry Space Surrey, a first-of-its-kind workshop dedicated to exploring how symplectic geometry – a branch of pure mathematics – can inform space mission design. A joint initiative co-supported by the STRUCTURES Cluster of Excellence, the Surrey Space Centre, the University of Surrey's School of Mathematics and Physics, and the Institute of Mathematics and its Applications, the event successfully gathered two traditionally isolated communities to foster new interdisciplinary collaborations.
While mathematical breakthroughs in the early 2010s began to link these fields, the workshop represented one of the first coordinated efforts to bridge the gap between astrodynamicists and mathematicians on a global scale. The workshop attracted 45 participants from eight countries and across all career stages – with a diverse mix of approximately 55% space engineers and 45% mathematicians. Beyond academia, the event included representatives from government agencies and the space industry to ensure a feedback loop between theoretical research and regulatory constraints.
Over four days, the workshop featured 20 research talks, five keynote presentations, a specialized mini-course and a tour through the satellite manufacturing facilities of Surrey Satellite Technology Ltd (SSTL). Sessions explored the Three-Body Problem and Computational Geometry, Cislunar Space Situational Awareness, Geometric optimal control, Floer theory and Contact Geometry. Researchers discussed questions such as using mathematical invariants for end-of-life satellite disposal or applying Floer theory to solve the “two-boost problem” for rocket travel between the Earth and the Moon – a prominent question in space mission design that asks whether a rocket can travel between any two points in the gravitational field of the Earth and the Moon using its engines only at the beginning and at the end of the journey.
“The goal was to open doors to the wider space sector and establish a direct connection between theory and application,” notes Dr Arthur Limoge (Postdoctoral Researcher at the Surrey Space Centre, and alumnus of the STRUCTURES YRC), who led the organization of the workshop alongside Dr Nicola Baresi and Prof. David J.B. Lloyd from the University of Surrey. This mission was underscored on the final day, when more than half of the participants toured the facilities of SSTL, an international leader in small satellite manufacturing that originated at the University.
Geometry Space Surrey was organised by the Surrey Space Centre with support from the School of Mathematics and Physics at the University of Surrey, the STRUCTURES Cluster of Excellence at Heidelberg University, and the Institute of Mathematics and its Applications. The workshop demonstrated the growing importance of interdisciplinary collaboration in addressing both fundamental scientific questions and practical challenges in the future of space exploration.

STRUCTURES Professor Michela Mapelli Takes Leading Role in Europe's Next-Generation Gravitational-Wave Observatory
Michela Mapelli, STRUCTURES Professor at Heidelberg University (Centre for Astronomy and Interdisciplinary Center for Scientific Computing) has been appointed Chair of the Observation Science Board (OSB) of the Einstein Telescope Collaboration, one of the major international projects shaping the future of gravitational-wave astronomy.
The Einstein Telescope is the planned next-generation European gravitational-wave observatory. Designed to be about ten times more sensitive than current gravitational-wave detectors, the Einstein Telescope is expected to detect gravitational-wave events from across most of the observable Universe and to investigate fundamental questions in astrophysics, cosmology, and fundamental physics. The Einstein Telescope has been included in the European Strategy Forum on Research Infrastructures (ESFRI) Roadmap since 2021 and has been identified as one of the key infrastructures of the future by the German Ministry for Research, Technology and Space.
With more than 700 members, the Observation Science Board plays a central role within the collaboration: it coordinates the development of the scientific goals of the Einstein Telescope, including studies of compact objects, cosmology, multimessenger astronomy, data analysis, and synergies with other electromagnetic and gravitational-wave observatories.
Mapelli has been a member of the Einstein Telescope Collaboration since its foundation in 2022 and has served as one of the lead editors of the “Blue Book”. Her research focuses on understanding the formation and evolution of binary black holes and intermediate-mass black holes across cosmic time. Since 2023, Heidelberg University has hosted one of the main research units of the Einstein Telescope Collaboration in Germany, with more than 20 members spread across the Zentrum für Astronomie, the Institut für Theoretische Physik, the Max Planck Institute for Astronomy, and the Heidelberg Institute for Theoretical Studies.
“I am deeply honored to serve as Chair of the Observation Science Board,” says Mapelli. “The Einstein Telescope will open an entirely new window on the Universe, and I look forward to working with the international community and with my co-chairs, Archisman Ghosh (Ghent University) and Paolo Pani (La Sapienza University of Rome), to help shape its scientific vision.”

The international LIGO–Virgo–KAGRA (LVK) Collaboration has released its latest catalogue of gravitational-wave detections, adding 161 new events observed between April 2024 and January 2025. The new data reveals evidence for the existence of second-generation black holes, provides the most precise sky localization ever achieved for a gravitational wave source, and offers the first measurement of three vibrational modes of a black hole.
The international network of gravitational wave detectors LIGO, Virgo and KAGRA (LVK) has announced today the online release of an updated catalogue of all gravitational wave events observed to date, named the Gravitational Wave Transient catalogue-5.0 (GWTC-5), with the corresponding scientific papers in submission to Astrophysical Journal and Astrophysical Journal Letters. The data analysed in this work were collected by the detectors between April 2024 and the end of January 2025, during a portion of the fourth observing run known as O4b. During this period, 161 new gravitational wave events were detected, bringing the total number of confirmed events observed by the network since the first detection in 2015 to an astounding 390. The international LVK network consists of the twin detectors of the US National Science Foundation Laser Interferometer Gravitational-wave Observatory (NSF LIGO) , the Virgo detector hosted by the European Gravitational Observatory in Italy and the Japanese KAGRA hosted by the Institute for Cosmic Ray Research (ICRR) of the University of Tokyo.
The new catalogue of gravitational wave events allows researchers to study black hole populations in unprecedented detail. “The new catalogue is a gold mine of discoveries, but it also poses new challenges,” says Michela Mapelli, STRUCTURES professor at the Center for Astronomy of Heidelberg University and directly involved in the studies. “For example, the spins – that is, the magnitudes and orientations of the rotations – of the components of two new binary black hole systems, GW241011 and GW241110, are exactly what we expect for second-generation black holes: black holes formed through the merger of smaller black holes.” At the same time, the new study finds that the masses of these black holes, about 10–20 times the mass of the Sun, are lower than predicted by most theoretical models. “This is a new enigma that will keep compact-object astrophysicists busy for quite some time!” says Michela Mapelli.
The new study also provides the most precise sky localization ever obtained for a gravitational-wave source. A signal known as GW240615 was identified within an area of just 6 square degrees, a very small portion of the celestial sphere. This exceptional performance was achieved thanks to the triangulation using data from all three detectors. At the same time, the catalogue includes the “clearest” gravitational wave signal ever detected, with a signal-to-noise ratio of 76.9. This signal, GW250114, reached Earth on January 14, 2025 and was generated by the merger of two black holes with nearly identical masses. After the collision, a newly formed black hole “rings” as it settles into its final shape – similar to how a bell vibrates and produces different tones. For the first time, scientists were able to measure multiple such “tones” – or vibrational modes – in a black hole signal, offering a new way to test Einstein’s theory of general relativity under extreme conditions. The results were in agreement with the predictions of general relativity.
Michela Mapelli is a STRUCTURES Professor working at the Center for Astronomy of Heidelberg University (ZAH), where she leads the group “DEMOBLACK - Demography of Black Hole Binaries in the Era of Gravitational-Wave Astronomy”. Her main research focus is understanding the formation of astrophysical black holes. Prof Mapelli joined STRUCTURES in 2023.
The LIGO–Virgo–KAGRA (LVK) Collaboration is the international network operating the world’s leading gravitational-wave observatories: the two LIGO detectors in the United States, Virgo in Italy, and KAGRA in Japan. Together, the collaboration brings together several thousand researchers from hundreds of institutions worldwide to detect and study gravitational waves from colliding black holes, neutron stars, and other compact-object mergers.
