LISA Consortium kick-off meeting June 26

With the adoption of the LISA mission by the European Space Agency, the scientific community is organizing itself into a revitalized LISA Consortium. To celebrate this transition and to begin organizing the scientific and engineering community around the exciting work needed to bring LISA to fruition, you are warmly invited to an online kick-off meeting that aims to bring together long-time LISA community members and people new to the LISA effort.

The evolved LISA Consortium kick-off meeting will be on June 26 at UTC 13:00-16:00 via zoom (the link will be available about a week before the meeting).

The meeting is open to all interested people regardless of consortium membership status and aims to share the evolution of the consortium structure and membership with brief presentations from the working groups. It will also present the wider LISA landscape, status of the mission, new consortium governance, and interaction with ESA, NASA, and the LISA Science Team. There will be ample time for Q&A.

SN2025gw: First IGWN Symposium on Core Collapse Supernova Gravitational Wave Theory and Detection, July 21-25 2025, Warsaw

The LIGO–Virgo–KAGRA Collaboration invites the core-collapse supernova (CCSN) astronomy and astrophysics community for a 5-day Symposium on July 21–25, 2025, at the University of Warsaw, Poland. CCSNe are among the most violent explosions known to occur in the Universe, and the next Galactic or near-extra-Galactic exploding massive star will be one of the most interesting, and most important, astronomical events of the century. This Symposium aims to bring CCSN experts together to address how to maximize the scientific potential of the first detection of core collapse supernova gravitational waves (GWs). The Symposium hopes to bring together GW astronomers and CCSN modelers, as well as neutrino and nuclear theorists, neutrino astronomers, and astronomers across the electromagnetic spectrum.

The sensitivity of GW detectors and progress on CCSN modeling are unprecedented, and we expect them to further advance in the coming years. A joint effort across communities has great potential to fully utilize these advances for CCSN GW discovery. Each day, we will host (before lunch) a set of lectures on one of the key topics listed below, to establish a common understanding and a common language. Moreover, each day (after lunch) will also include invited and contributed talks, as well as discussion. The focus topics of the Symposium are:

Day 1: CCSN Theory
Day 2: CCSN Gravitational Wave Detection and Parameter Estimation
Day 3: CCSN Neutrino Detection
Day 4: CCSNe across the Electromagnetic Spectrum
Day 5: CCSNe over the Next Ten Years

The proceedings of the Symposium will be published in a special issue of Classical and Quantum Gravity. We hope the proceedings will serve as a reference for students, postdocs, and faculty in, or entering, the field, serve to capture the current state of core collapse supernova gravitational wave astronomy and astrophysics, outline lessons learned, and provide recommendations for future development.

Everyone who wishes to advance the field of CCSN GW science is welcome!

EREP 2025, Spanish and Portuguese Relativity Meeting, September 1-5, 2025, Alicante

The Spanish-Portuguese Relativity Meetings (EREPs) are a long-standing scientific tradition that began in 1977. Since then, they have served as a key forum for the Portuguese and Spanish communities working in General Relativity and Gravitation, promoting collaboration and the exchange of ideas across a broad range of topics. Organized annually by different research groups from both countries, EREPs have become the most prominent conference on gravitation and relativity in the Iberian Peninsula.

The 2025 edition (EREP 2025) will take place in Alicante, Spain, from September 1st to 5th, 2025. We warmly invite you to join us for a week of stimulating scientific discussions in a vibrant and sunny Mediterranean setting. As in previous editions, EREP 2025 will bring together researchers from across the Iberian Peninsula and beyond, offering a dynamic program in a friendly and collaborative atmosphere.

APPEC Tech Forum Vacuum & Cryogenics – Industry meets Academia, November 24-26, 2025, Maastricht

European physicists in astro-particle physics as well as in neighboring fields are planning the next generation of experiments to be built within the next decade. The success of the projects in direct dark matter detection, low energy neutrino physics, neutrino properties, gravitational wave detection as well as related accelerator-based experiments in particle and nuclear physics highly depends on challenging technologies in the domain of vacuum and cryogenics. The first event of this series, focusing on vacuum and cryogenics,  took place in Darmstadt/Germany in 2012. A brochure was published after the meeting, providing an overview of participating  experiments and companies.

For a thorough planning of all stakeholders it is important to carefully elaborate the timing of the projects and their needs as well as the market availability of key products. The APPEC Technology Forum is organized jointly with the international union of vacuum societies IUVSTA, national vacuum societies from the Netherlands and Germany, Maastricht University, NIKHEF and the Karlsruhe Institute of Technology (KIT) to identify synergies between projects from neighboring fields. It shall provide a discussion forum for companies, project scientist and funding agencies to define future ways of boosting cooperation to the benefit of all stakeholders.

Full registration is expected to be available im May 2025. However, you can already register your e-mail address to help us with planning and to receive updated information, as it becomes available. You can also indicate, if you are interested in presenting a poster for your experiment, or if you would like to present products and information about your company.

At the end of the meeting we offer a visit to ET-Pathfinder, a R&D facility for the development and testing of technologies for the next generation gravitational wave observatory, the Einstein Telescope.
