The thematic school Gravitational Waves emission from proto-neutron stars and Neutron Star mergers (GWsNS-2026) is a graduate school that will cover several aspects of the gravitational wave (GW) emission from neutron stars, with special attention to neutron star mergers and proto-neutron stars. This is the 2026 edition of the event GWsNS-2023 (check the website for the lecture material of the previous edition!), and will take place at the Station Biologique de Roscoff (Brittany, France), a CNRS facility with full conference infrastructure and on-site accommodation.

The rapidly evolving field of multi-messenger astronomy and the arrival of third-generation detectors (like the European Einstein Telescope project and the American Cosmic Explorer) are expected to lead to further advances in both our understanding of neutron star astrophysics and the possibility of constraining theoretical models of ultra-dense matter with astronomical observations.

A complete understanding of the observations expected from third-generation gravitational-wave detectors will only emerge through a close dialogue between theory and data. Achieving this demands a broad and interdisciplinary skill set — spanning nuclear and hadronic physics, numerical relativity simulations, Bayesian inference, and multi-messenger astronomy.
The GWsNS-2026 school aims to bring together both young and experienced researchers wishing to gain a comprehensive view of this rapidly evolving and highly interdisciplinary field.

The WE Heraeus Physics School and the 62nd Karpacz Winter School in Theoretical Physics "Multimessenger Astrophysics and Cosmology" will be held from 28 February to 6 March 2026. 

Compact stars, dense remnants of supernovae, compress about 1.4 solar masses into a 10 km radius—reaching densities beyond atomic nuclei. Their extreme compactness makes them unique laboratories for high-density matter. Gravitational-wave detections of binary neutron star mergers now allow direct probes of such conditions, with hot, dynamic post-merger remnants offering complementary insight to cold pulsars.

With next-generation observatories like the Einstein Telescope and Cosmic Explorer, multi-messenger astrophysics—combining gravitational waves, electromagnetic signals, and neutrinos—will sharpen constraints on the dense-matter equation of state, extreme gravity, and heavy-element nucleosynthesis. Mergers also serve as standard sirens, enabling independent measurements of the Hubble constant.

The school will cover the thermal history of the Universe after its first second, from the quark–hadron transition to neutrino decoupling, linking microphysics to cosmological observables. Topics include the Hubble tension, modified gravity, primordial magnetic fields, compact-object mergers, future gravitational-wave science, and primordial black holes as dark-matter or galaxy-seed candidates—offering a unified view across astrophysics, cosmology, and particle physics.

The scientific programme will consist of lectures and hands-on sessions delivered by experts from ICE and collaborating institutions.

Core themes will include, but are not limited to:
-Radiation processes and fundamental interactions

-Gamma-ray astronomy
-Neutrino physics and detectors
-Gravitational wave theory and data analysis
-Hands-on data analysis sessions (e.g., Fermi data, LIGO/Virgo)
-Machine learning applications in multimessenger research

Detailed session titles, lecturers, and the full list of topics can already be found on the school’s website.

Dates and Venue
The School will run from 6 to 14 July 2026 at the Institute of Space Sciences (ICE-CSIC), located on the Campus of the Universitat Autònoma de Barcelona (UAB) in Bellaterra (Barcelona). The ICE building and possible accommodation are within the UAB campus area.

Participation, Registration, Fellowships
Applications are welcomed from Master’s and PhD students, as well as early-career postdoctoral researchers with a strong interest in multimessenger astrophysics. Information on registration procedures, selection criteria, and possible financial support are provided on the school’s website. Registration will close on March 20, 2025. Announcements of accepted participants and fellowships are expected to happen before April 15.

Contact and Further Information
Further details, including the official registration link and programme are published on the Summer School website. Participants are encouraged to monitor the event page for announcements and logistical guidance, and register as soon as possible.

Black holes are among the most fascinating objects in the universe. From cosmological, galactic and stellar scales, where black holes are integral pieces in the formation and evolution of different structures, to microscopic scales, where the study of the fabric of spacetime and black hole interiors are interrelated, black holes are ubiquitous in all research areas in which gravity is a prominent actor. A proper understanding of many aspects of modern physics requires being familiar with the concept of black hole; conversely, comprehending black holes in all their dimensions requires extensive knowledge in diverse branches of physics, including geometry, thermodynamics, fluid dynamics, quantum field theory and numerical analysis.

This summer school will offer PhD and MSc students the opportunity to gain a solid understanding of the theory, phenomenology and observations of black holes and acquire a broad perspective of current research tendencies. Lectures covering each of these aspects will be delivered by three leading international experts.

The school will take place in the historical Carmen de la Victoria at the heart of the Albayzín, the old Arab neighborhood of Granada, where all participants will be hosted on a full board basis. The Carmen de la Victoria faces the famous Alhambra, the place of inspiration of the popular book by Washington Irving that the name of the school pays homage to.

Understanding the gravitational interaction is one of the great scientific endeavors of the 21st century. The Nobel Prize-winning discovery of gravitational waves in 2015, and subsequent detections by the LIGO-Virgo-KAGRA Collaboration, have marked a revolutionary step forward in physics and astrophysics by opening an entirely new window for exploring the Universe. Future upgrades to these detectors, along with upcoming facilities such as LISA and the Einstein Telescope, promise even more breakthrough discoveries that the next generation of scientists will need to interpret.

The School on Gravity (22–26 June 2026, Copenhagen) will introduce junior scientists—graduate students and advanced undergraduates with a background in general relativity—to a wide range of foundational topics in the exciting new field of gravitational wave physics. Topics will span from the theory of motion, to new challenges introduced by quantum physics, to the astrophysics of black holes and source modeling for gravitational-wave detectors.

The School on Gravity will take place in the legendary Auditorium A of the Niels Bohr Institute, inviting students and lecturers to challenge current paradigms in gravitational physics in the spirit of the quantum revolution that unfolded in this very room.

The members of the Scientific Organizing Committee for the School of Gravity are Vitor Cardoso (Director of CoG), Emil Bjerrum-Bohr, Jose Ezquiaga, Troels Harmark, Niels Obers, Marta Orselli, Alessia Platania, Johan Samsing, Maarten van de Meent, Ziqi Yan.

The local organizing committee is composed of Vitor Cardoso and Jose Ezquiaga.
