Explaining dark matter is a significant challenge in modern theoretical physics. Among the candidates, macroscopic dark matter, such as primordial black holes or wave-like dark matter, has recently gained considerable attention. With the sophisticated advancements in numerical relativity, the foundation for quantitatively investigating primordial black holes has been established. Gravitational microlensing is currently one of the most promising methods for probing the presence of primordial black holes, and through it, we expect to observationally explore their mysteries. Gravitational waves are a powerful tool for observing the characteristic effects unique to black holes. With the rapid development of gravitational wave detectors, we anticipate that soon we will be able to obtain information about primordial black holes through gravitational waves.
Meanwhile, wave-like dark matter is expected to leave various observable evidence due to its influence on electromagnetic fields. To detect this, methods such as using a cavity within a strong magnetic field or employing light interferometers are being researched. Given that existing gravitational wave detectors also measure the effects gravitational waves have on electromagnetic waves, it becomes clear that as these devices become more refined, they will function as detectors for both wave-like dark matter and gravitational waves. Through this connection, the topic of macroscopic dark matter is drawing the combined interest of astrophysicists, particle physicists, and experimental physicists.
This workshop is intended to produce tangible research outcomes through short-term intensive collaboration. Participation will be by individual invitation rather than public call, though the main talks will be open to all.
