Dark matter and black holes

→ Asia/Tokyo

Description

Dark matter and black holes

This workshop will bring together astronomers, cosmologists, and particle physicists to discuss the fascinating connections between black holes and dark matter. ย  What can be learned from the intertwined cosmological histories of dark matter and black holes?ย  What are the interactions and observational consequences of various dark matter candidates in the presence of black holes? Is dark matter composed of black holes?ย  Was the formation of supermassive black holes influenced by dark matter?ย  Can dark matter cause neutron stars to collapse into black holes? ย  Can black hole observations reveal the particle properties of dark matter? ย  We hope to shed light on these and other questions that surround the profound mysteries of black holes and dark matter.

Dates

1-5 December, 2025

Topics

  • Microlensing search for primordial black holes (PBH)ย ย ย 

  • Astronomical observations of supermassive black holes.ย ย 

  • WIMPs and black holes.ย ย 

  • Axions and black holes

  • Formation of PBHs.ย ย 

  • Interactions of PBHs with compact stars as means for their detection
