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.

Summer School on String Theory and Summer School on Gravitational Waves, July 31 – August 10, 2025 On the theory and phenomenology tracks of PSI, we are organizing two schools in parallel—one on String Theory and the other on Gravitational Waves. School Website

First International Latin American Conference on Gravitational Waves: 10 years since first detection September 15–19 2025 at INPE Sao Paulo A decade ago, science witnessed an extraordinary milestone: the first direct detection of gravitational waves, predicted by Albert Einstein in his Theory of General Relativity in 1915. These ripples in spacetime, generated by extreme cosmic events such as black hole mergers, remained merely a theoretical prediction until September 14, 2015, when the LIGO (Laser Interferometer Gravitational-Wave Observatory) experiment captured this historic signal.

CoCoNuT Meeting, December 11-13, 2024 in Valencia The CoCoNuT Meeting is a series of workshops aiming at fostering collaboration among relativistic astrophysicsgroups, specially within Europe. The series has been taking place yearly since 2009 and this year is hosted by the University of Valencia. Meeting Website

DTP/TALENT 2024, Nuclear Theory for Astrophysics, July 15 – August 2 2024, Trento Nuclear physics and astrophysics are strongly linked through neutron stars, compact objects that represent the densest form of matter in the universe. Neutron stars also have strong synergies to nucleosynthesis and the origin of the heaviest elements in the cosmos. This TALENT school will cover: 1) the equation of state of neutron-rich matter and new constraints inferred from nuclear theory, experiment and observations, 2) core-collapse supernova as the birthplace of neutron stars, and 3) neutron star mergers and gravitational waves to probe the neutron-star interior.

First Stars VII, May 20-23, 2024, New York The „First Stars“ conference series has brought together astronomers and astrophysicists working on the high-redshift universe roughly every four years since 2007[*]. The seventh edition, First Stars VII, will be hosted in New York City by the Flatiron Institute 20-23 May 2024. The meeting will feature invited review talks, contributed talks and posters and will leave ample time for discussion. The scientific program will balance theory, observations, and numerical simulations. Conference Website
