LISA School for early-career scientists, October 6-17, 2025 in Les Houches

Gravitational-wave observations are providing a new view on the Universe: from the high-frequency observations by ground-based facilities, to the tantalising evidence of low-frequency gravitational waves reported by pulsar timing array collaborations in 2023. It is an exciting time for GW astronomy and the LISA space mission will bridge the gap between the high and low frequency. The LISA mission is led by the European Space Agency (ESA) with NASA partnership. Anticipated observations include black hole binaries (supermassive, intermediate mass), Galactic compact object binaries; extreme mass ratio inspirals, early inspiral of stellar-mass black hole binaries, cosmological sources as well as other possible unforeseen sources.

Last year, ESA formally adopted the LISA mission. This crucial milestone marks the transition from study phase to implementation phase. Launch is planned for the mid-2030s.

Why a LISA School?

LISA is a first-of-its-kind mission. The instrumentation and data analysis challenges will require a significant amount of development. Building expertise and tools to address these challenges is essential to ensure the success of the mission and maximise the scientific returns. This LISA School will gather young researchers interested in LISA science to foster collaborations, encourage interactions, and train them in the multidisciplinary aspects of the missions and its science. The recent ESA Adoption makes the coming years opportune time to bring the early career community of LISA together.
Scientific objectives

The key objectives of this LISA school are:

  • broaden the knowledge of early-career scientists with lectures on LISA science;
  • provide hands-on experience in some of the current LISA software tools;
  • present the pioneering LISA instrumental design and methods;
  • enable early-career scientists (the future research leaders by the launch of the mission) to meet in person, network, share ideas, and foster collaboration;
  • inform early-career scientists on the LISA mission organisational structure and plans;
  • develop general skills and a welcoming collaboration environment.

The school will welcome approximately 50 in-person participants. Sessions will be taught by LISA experts (we anticipate approximately 15 expert teachers). When inviting teachers for the school, we have favoured early-career experts and paid special attention to gender representation.

Registration and timeline

Pre-registrations are now open, and will close July 11th at midnight.

The school is limited to 50 students, and will be served on a first-come, first-serve basis. Your registration confirmation will be sent mid-July and payment is expected before end of July.

We do not allow for partial participation, i.e., students are expected to attend the 11 days of school.

Participation fees

Student participation fees for the whole school amounts to EUR 900.

This includes subsistence (from dinner on the day of arrival to lunch on the day of departure), accomodation, and other organization fees (coffee breaks, library, IT space, leisure facilities). It does not include transport to and from Les Houches, or any extra activities.

We plan to support students with limited financial resources; you can apply for this support by filling the “Support Request” field in the pre-registration form.

Les Houches School of Physics

Les Houches is a village located in Chamonix valley, in the French Alps. Established in 1951, the Physics School is situated at 1150 m above sea level in natural surroundings, with breathtaking views on the Mont-Blanc mountain range.

Les Houches Physics School is UAR 2002 run by Université Grenoble Alpes (UGA).

The 5 School Partners are

  • UGA, the Institut National Polytechnique (Grenoble-INP),
  • the Centre National de la Recherche Scientifique (CNRS),
  • the Commissariat à l’Energie Atomique (CEA), and
  • the Ecole Normale Supérieure de Lyon (ENS Lyon).

Quantum Universe 2025, October 27-31, 2025 in Avellino

The conference aims to bring together researchers from particle physics, gravitational physics, cosmology, and quantum mechanics. Modern physics faces several unresolved issues, from puzzles in theoretical particle physics (e.g. hierarchy problem, Grand Unification) to experimental anomalies (e.g. muon g-2, neutron lifetime), and questions surrounding dark matter, dark energy, quantum gravity, and the foundations of quantum mechanics. These branches are more interconnected than ever, with breakthroughs in one area often providing solutions in others. The conference will offer a platform for interdisciplinary collaboration, allowing experts to share insights across these fields.

Proceedings of QU2025 will be published in International Journal of Geometric Methods in Modern Physics (IJGMMP)

The event will take place in Avellino at the Borbonic Prison, a significant historical and architectural landmark in the city center. Built in the early 19th century during the Bourbon rule, the structure reflects neoclassical design principles and has served various functions over time, preserving its historical essence.

The conference fee is €350, which includes a welcome aperitif, lunches, a welcome kit, the social dinner, and the proceedings. This reduced fee is available until July 31. After this date, registration will still be possible, but the fee will increase to €450.
Avellino

Nestled in the heart of the Campania region, Avellino is a city of rich historical and cultural significance, surrounded by the rolling hills of Irpinia. Known for its deep-rooted traditions and vibrant local identity, Avellino blends historical heritage with a dynamic modern character. The city’s historic center features notable landmarks such as the 12th-century Clock Tower and the neoclassical Cathedral of the Assumption.

Avellino is also a gateway to the scenic landscapes and renowned wineries of Irpinia, a region celebrated for its fine wines, including Taurasi, Greco di Tufo, and Fiano di Avellino. Its proximity to important cultural and archaeological sites, such as Benevento and Salerno, enhances its appeal as a destination. With its rich gastronomy, strong artisan traditions, and lively cultural scene, Avellino offers a unique combination of history, nature, and enogastronomic excellence in southern Italy.

Multi-Messenger Astrophysics in the Dynamic Universe, January 26 – February 27, 2026 at YITP Kyoto University

Astrophysics has finally entered a new era, transitioning from the multi-wavelength observation approach of the 20th century to the era of multi-messenger observations. The discovery of the binary neutron star merger event GW170817 in 2017 marked the beginning of this shift, as it was first detected through a gravitational wave and gamma-ray burst, followed by electromagnetic counterparts observed across various wavelengths, including X-ray, optical, infrared, and radio. In addition to gravitational waves, significant advancements have also been made in other multi-messenger signals, such as high-energy neutrinos and high-energy gamma rays. Traditional X-ray, optical, infrared, and radio observations are not only achieving higher sensitivities but are also making great strides in discovery science through time-domain astronomy, focusing on transient events.

The progress in multi-messenger astrophysics is unveiling the dynamic universe shaped by the evolution to black holes. Long-standing fundamental questions — such as the evolution of stars and galaxies, the mechanisms behind jet and particle acceleration, and the origin of elements — are seeing substantial advancements. At the same time, new mysteries are emerging as we deepen our understanding of the final fate of gravitational energy. These developments are also driving progress in cosmology and fundamental physics.

In this long-term workshop, we invite leading researchers from around the world to engage in in-depth discussions on the following key topics in astrophysics.

Compact star mergers and gravitational waves Gamma-ray bursts, supernovae and kilonovae Supermassive black holes, tidal disruption events and QPEs High-energy gamma-rays and neutrinos Fast radio bursts and magnetars Origin of binary black holes and neutron stars Population III stars and galaxies Related topics

During the workshop, participants stay at YITP with desks and other facilities. They can engage in extensive discussions with fellow participants in the relaxed atmosphere of Kyoto.
