– About HEDLA/HEDS:

We are pleased to announce the 15th International Conference on High Energy Density Laboratory Astrophysics (HEDLA), to be held from April 20 to 24, 2026, at Pacifico Yokohama in Yokohama, Japan. This conference will be co-located with the International Conference on High Energy Density Science (HEDS) as part of the Optics and Photonics International Congress (OPIC).

HEDLA is a topical conference series that began in 1996 and has been held approximately every other year since. Its goal is to use and develop laboratory experiments to understand high-energy-density phenomena in the universe. HEDS covers high-energy-density science using high-power lasers and their applications.

– Scope:

High-power lasers and pulsed-power facilities enable the creation of extreme states of pressure and temperature that exceed those attainable under terrestrial conditions. Such high-energy-density states provide a powerful platform for exploring fundamental processes in astrophysical plasmas, which remain among the most compelling subjects in modern science. Laboratory astrophysics offers a unique and complementary research approach, advancing our understanding of astrophysical phenomena through controlled experiments in conjunction with astronomical observations and theoretical or simulation studies, while fostering collaboration across diverse scientific communities.

Proposed topics include, but are not limited to:

• Fluid and Collisional Plasma Dynamics
• Collisionless Plasmas and Particle Acceleration
• Transport and Atomic/Radiative Processes
• Dense Plasma Physics
• New Frontiers in High-Energy-Density Science
