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,…

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. Conferece Website
