Venue: Lecture Hall, Kavli IPMU, Kashiwa, Japan


    The focus on primordial black holes was brought in sharper focus by recent progress in theoretical understanding as well as observations, in traditional and gravitational wave astronomy.  There is growing evidence that black holes exist, but their origin is not well understood.   Black holes with masses, roughly, ten times the solar mass have recently been discovered in gravitational waves. Observations confirm the existence of supermassive black holes in active galaxies, as well as a large black hole at the center of Milky Way.  While explosions of massive stars can lead to formation of black holes, our understanding of the mass function of astrophysical black holes is limited. There is no compelling explanation of how astrophysically produced black holes could grow to be supermassive in a short amount of time since the big bang.   Black holes of primordial origin could be an important component of dark matter in today’s universe, and they could be the key to a range of astrophysical puzzles.  The subject of primordial black holes has a strong overlap with scientific programs at Kavli IPMU, and it engages particle physicists, astrophysicists, and cosmologists to work together, building on synergy of the multidisciplinary institute.
