an EU-funded project built by and for the astroparticle and the astronomy communities
On the 16th and 17th of September was held in Paris the kick-off meeting for the Astrophysics Centre for Multimessenger studies in Europe – ACME. This HORIZON-INFRA-2023-SERV-01 EU-funded project coordinated by Centre national de la recherche scientifique CNRS aims to realize an ambitious coordinated European-wide optimization of the accessibility and cohesion between multiple leading astroparticle and astronomy research infrastructures, offering access to instruments, data and expertise, focused on the new science of multi-messenger astrophysics.
With 40 world-class collaborating institutions from 15 countries, ACME brings together the astroparticle and astronomy communities in a joint effort to forge a basis for strengthened long-term collaboration between these research infrastructures irrespective of location and level up access opportunities across Europe and beyond.
ACME objectives are to implement the Astroparticle Physics European Consortium’s (APPEC) and the Planning and Advisory Network for European Astronomy’s (ASTRONET) roadmaps’ recommendations and act as a pathfinder to broaden and improve access to the respective research infrastructures services and data, assess and evaluate new models for better coordination and provision of at-scale services, provide harmonized trans-national and virtual access, develop centres of expertise, improve science data products management, improve interoperable systems for rapid identification of astrophysical candidate events and alert distribution to optimize follow-up observations, provide training for a new and broader generation of scientists and engineers, open the astrophysics and astroparticle physics data sets to other disciplines and increase citizen engagement.
The ACME project coordinator Prof. Antoine Kouchner (APC – CNRS/Université Paris Cité), and co-coordinator Paolo D’Avanzo (INAF), represent each community to ensure balance and drive cross-domain collaboration.
“With ACME the astrophysics and astroparticle communities are coming even closer together. The bridge between the communities has already been strengthened during the preparation phase for the proposal. This augurs an even stronger collaboration and a productive dialogue to advance science” says Antoine Kouchner, Vice-President of International Relations at Université Paris Cité, Deputy Director at APC and Vice-Chair of APPEC.

This survey aims to engage with the European Astroparticle Physics community in order to collect useful information for the next APPEC roadmap. The data collected will be beneficial both for compiling statistics and gathering information. We therefore warmly invite you to participate individually, as a research group, or as a representative of a collaboration in the present survey.
Your opinion is valuable to us.
We ask that the survey be completed by the end of November 2024.
Borexino succeeded for the first time to measure the entire energy spectrum of neutrinos that the Sun produces exploiting techniques that allowed to obtain unprecedented levels of radiopurity, which as of today represent the state-of-the-art. Experiments currently underway or in preparation, such as those studying rare events (dark matter direct detection, neutrinoless double beta decay, reactor neutrinos) use technologies that largely derive from Borexino.
Borexino definitively helped answering Humanity’s age-old question about how the Sun and stars shine. This is a historic result that has been expected for more than eighty-five years when, in late 1930s, Hans Bethe and Carl Friedrich von Weizsäcker hypothesized what Borexino has now confirmed for the first time: stars are producing energy by the so-called pp-chain and CNO bi-cycle processes.

Alongside hypothetical dark matter particles, neutrinos from the sun have long been predicted to be observables in detectors built to search for dark matter nuclear recoil signals with large time projection chambers filled with liquid Xenon. Observing this feeble signal, with energy barely detectable, requires excellent detector performance and sophisticated signal-to-background discrimination. This has been demonstrated by XENONnT operating at the Gran Sasso Laboratory in Italy.
A slight sign of 8B signal is also reported at the same meeting by the PandaX-4T a similar detector operated at the Jingping underground laboratory in China.
We are happy to announce Carlos Peña Garay as the newly elected Chair of the APPEC General Assembly, who will start his term from December 2024, and Julie Epas as the new General Secretary of APPEC.

Carlos Peña Garay, current director of the Laboratorio Subterráneo de Canfranc (LSC) in Spain, has accepted to become the new Chairperson of APPEC, following his election at the APPEC General Assembly held on June 5th 2024 in Amsterdam.
Carlos made major contributions to the Astroparticle Physics domain. Between 1998 and 2003, he contributed to the solution of the Solar Neutrino Problem, which proved that neutrinos have a finite mass. He also significantly contributed to other various areas of research, including high-energy neutrinos, low-energy positrons, neutrino-less double beta decay, and dark matter searches. Carlos’ leadership at LSC involves developing sensitive radiopure detectors and hosting experiments in underground labs to reduce cosmic ray background.
Carlos’ vision for APPEC over the next two years is to represent the Astroparticle Physics community views at their best in Europe’s decision-making process, for the long-term future of the field, and to be influential in strengthening the support and resources to execute them. A major responsibility will be to lead the preparation of the European Astroparticle Physics Strategy 2027-2036 by coordinating the community views and supporting all actions required by the APPEC Scientific Advisory Board to prepare the report.
To ensure a smooth transition, the Chairperson of APPEC will change in December 2024. Until the end of the year, newly elected Carlos Peña Garay will shadow the current Chair Andreas Haungs (Karlsruhe Institute of Technology) to support him in coordinating APPEC activities.
During the same APPEC General Assembly, a new General Secretary was appointed. Julie Epas (APC Laboratory IN2P3/CNRS) replaces Katharina Henjes-Kunst (DESY). Julie Epas is a very experienced project manager in science and technology projects. Julie has been the project manager for the functional center of APPEC in Paris since 2021.
We would especially like to thank former Secretary General Katharina Henjes-Kunst for her intensive work and all her valuable contributions to the astroparticle community over the past years.
The European Astroparticle Physics Consortium (APPEC) announces that the Mid-Term Update of the European Astroparticle Physics Strategy 2017-2026 has been successfully finalised and approved by its General Assembly. The updated roadmap was developed in collaboration with the APPEC Scientific Advisory Committee and the wider community and neighbouring disciplines. The presentation of this important update took place during an event entitled “The Future of Astroparticle Physics in Europe” where also the community presented the plans and ideas of current and future research facilities and experiments in a very lively poster session. The connections between experiment and theory as well as the synergy potential and complementarity with the astrophysics and astronomy domain were discussed at this event.
The mid-term update shows that the APPEC European Strategy for Astroparticle Physics 2017-2026 is well on track to be realised. Most of the strategic goals are on schedule and are expected to be achieved. However, it has become clear that some goals are no longer achievable, leading to adjustments in the strategic goals. At the same time, new strategic goals are emerging in other areas. Projects such as a new European gravitational wave detector (Einstein Telescope) are in an advanced stage of development. This has prompted the APPEC community to make some medium-term course adaptations in the strategic goals of various scientific astroparticle physics topics.
“Astroparticle physics uses large-scale research facilities to detect the sources and properties of messengers from the universe, which are often set up in remote locations such as on the South Pole, deep in the Mediterranean Sea, on high mountains, in the Argentinian pampas or in large underground laboratories. This implies a high need for coordination, especially in the area of data processing, as the data from these observatories must be brought together, preferably in real-time, to be of optimal use,” says Dr Andreas Haungs from KIT (Karlsruhe Institute of Technology), Chair of the APPEC General Assembly. “These large infrastructures, especially underground laboratories, are crucial to maintain and develop. An initiative for much closer co-operation between European underground laboratories is welcomed by APPEC. The resources available for the operation of existing large infrastructures, as well as for investment in those currently under construction or planned for the future, will be reviewed globally. The idea is that, despite the constant struggle for more resources, the field’s basic budget offers it a promising future.”
“Progress in astroparticle physics goes hand in hand with profound changes in the social and societal environment of science in general and thus also of astroparticle physics. Attracting and retaining talent is increasingly becoming a challenge. Social safety in all aspects is increasingly emphasised and open science is rapidly becoming the norm. Consideration of societal impact in the widest sense is now a must. Therefore, the strategic goals for how we want to operate as scientists in astroparticle physics have become more important and clearer.” emphasised Prof. Sijbrand de Jong (Radboud University Nijmegen), who, as head of the APPEC Scientific Advisory Board, presented the roadmap update to the interested audience.
It is with great sadness that we have received the news that you have left us far too soon. With your calm and empathetic manner and your broad expertise in the entire field of research, you made an important contribution to APPEC. In particular, as CNRS representative in APPEC, you were co-responsible for the elaboration and creation of the “European Strategy for Astroparticle Physics 2017-2026” for several years. Until recently, you were also APPEC’s contact person for the US Snowmass and P5 strategy process. Only recently we contacted you to give an update on this process at our meeting, and only a few days later we received the news of your death, which filled us with great sadness.
APPEC and the astroparticle physics community owe you a lot and we always felt very comfortable in your presence. We will miss you.

The Euclid satellite was sent into orbit on July 1, 2023. Over a period of six years, the European Space Agency’s (ESA) Euclid mission and its space telescope will construct an extensive cosmic map, spanning both space and time, to investigate the nature and the development of the dark Universe. Euclid represents the outcome of a global partnership, engaging researchers from CNRS-INSU and CNRS-IN2P3. The Euclid Consortium, comprising over 1,500 scientists hailing from 300 diverse research facilities and institutions in 17 distinct nations, was responsible for supplying the scientific tools and will actively engage in generating and examining the scientific data.

ANTARES took its last data on February 2022 and since then it has been completely dismantled, but the research, publications, and data releases are still ongoing.
Recently, the latest ANTARES data samples from the track-like and shower-like events induced by different neutrino interactions were used to test several models that predict the neutrino flux produced from the interaction of cosmic rays with atomic and molecular gas in the Milky-Way.
The results of the search for a diffuse neutrino emission from the Galaxy with a likelihood method using the latest ANTARES data available were presented at the ICRC 2023 conference and the paper can be found in the Proceedings of Science https://pos.sissa.it/444/1084/pdf, with the final conclusion that a combination of the ANTARES data with data from other experiments like
KM3NeT and IceCube would strengthen even more the evidence for the existence of neutrino flux coming from the Galactic Plane.

The next application round will begin on SEPTEMBER 25, 2023 and close on NOVEMBER 5, 2023.
