14th Cosmic-Ray International Studies and Multi-messenger Astroparticle Conference, July 13-17 2026, Sorrento

The 14th CRIS-MAC Conference will be held in Sorrento from 13 to 17 July 2026.

The Conference is jointly organized by the Department of Physics and Astronomy “E. Majorana” of the University of Catania, and by the Department of Physics and Chemistry “E. Segrè” of the University of Palermo and the Department of Physics “E. Pancini” of the University of Napoli Federico II and by the Catania and Napoli Divisions of the National Institute of Nuclear Physics (INFN).

As in previous CRIS editions, the conference will focus on fundamental topics in astroparticle physics with special emphasis on the multi-messenger astronomy studies. For this reason the conference acronym has been changed to CRIS-MAC (Cosmic-Ray International Studies and Multi-messenger Astroparticle Conference) while retaining the old CRIS series numbering.
The main focus of the CRIS-MAC conference is the multi messenger aspects of astroparticle physics which naturally includes fields such as cosmic-ray physics, gamma-ray and multi-wavelength astronomy, astrophysical neutrinos and gravitational waves.

The program includes invited lectures, contributed talks, posters and flash talks.

As in the past, the CRIS-MAC 2026 is addressed to scientists in the field as well as to PhD and graduate students. We will encourage lively and informal discussions among participants.

Theoretical Tools for Gravitational Wave Physics, November 3-5 2025 at ETH Zurich

As we progress into the era of gravitational wave (GW) astronomy, robust theoretical frameworks are essential for interpreting data and uncovering new physics. This workshop is dedicated to the deployment of tools from theoretical physics for GW phenomenology.

Key topics include:

Modern theoretical approaches for modeling GWs from compact binaries, such as effective field theories and techniques inspired by quantum field theory.
Tidal response and quasi-normal modes of compact objects, which provide insights into their internal structure and offer potential signatures of new physics.
Gravitational wave memory effects, linked to asymptotic symmetries and soft graviton theorems, provide further tests of GR and insights into cosmology.

Bringing together experts from across gravitational theory and related fields, the workshop aims to deepen our theoretical understanding required to fully exploit the potential of incoming GW observations.

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).

LISA prime industrial partner selected: Construction of ESA’s ambitious LISA Mission begins

(June 17, 2025) Today, the European Space Agency (ESA) and OHB System AG sealed their agreement to build ESA’s Laser Interferometer Space Antenna, LISA. A bold scientific enterprise, the triple-spacecraft mission will be the first space-based observatory to study gravitational waves: ripples in spacetime caused by the most powerful events in the Universe, such as pairs of supermassive black holes colliding and merging.

“We are delighted that the European Space Agency has now chosen the industrial partner who will take on the manufacturing of LISA, marking another major step towards launch”, says Dr Jonathan Gair, chair of the LISA Consortium council and Group Leader at the Max Planck Institute for Gravitational Physics in Potsdam, Germany. “A decade ago, the success of the LISA Pathfinder Mission (LPF) demonstrated that the ambitious vision behind LISA was feasible. Building on that breakthrough, researchers and engineers have worked tirelessly to refine and develop the full-scale LISA mission”.

“The scientific and technological development of LISA has largely been completed. We are pleased to now hand over this unique project to OHB for industrial production”, says Karsten Danzmann, director at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute, AEI), and director of the Institute for Gravitational Physics at Leibniz University Hannover. “After most of LISA’s key technologies have already been successfully tested in space with LISA Pathfinder (LPF), the scientific community will continue to support the construction and provide input where needed.” 

The efforts of the LISA Consortium, the scientific community behind LISA that works closely together with the space agencies, culminated in the European Space Agency’s formal adoption of LISA in January 2024, followed by the publication of the LISA Definition Study—the so-called ‘Red Book’—in February. This comprehensive document captures the results of years of dedicated work during the mission’s definition phase.

Now, with LISA on track for launch, our focus shifts to maximizing the scientific return of this pioneering mission, which promises to open an entirely new window onto the gravitational universe.
