OBJECTIVES

In 2015, a black hole binary was detected through gravitational waves. Since it was suggested that the system might consist of primordial black holes, researchers not only in cosmology and gravitation but also in particle physics and astrophysics have increasingly recognised the importance of primordial black holes. As a result, research on primordial black holes has developed rapidly and expanded significantly over the past decade. This workshop is organised to promote international collaboration, foster mutual understanding, and encourage future constructive and cutting-edge joint research.

The workshop will bring together researchers conducting cutting-edge research on various aspects of primordial black holes, providing a forum for in-depth discussion and interaction. The first workshop in this series was held at Rikkyo University in March 2023, and the second at Nagoya University in October 2024. This meeting is the third in the series.
