After aLIGO detected the gravitational wave (GW) produced by mergers of binary black holes (BHs), researchers have aggressively studied the origin of the BHs with masses of the order of O(10) M. In addition to astrophysical origins of BHs, one of the attractive candidates of those massive BHs should be Primordial Black Holes (PBHs), which were produced in the early Universe, e.g., through collapses of large curvature perturbation at small scales produced by inflation, not through normal collapsing stars.  In addition to the candidates of the sources for the GW events, it is exciting that PBHs can be also whole or in part of dark matter. Therefore, nowadays PBHs have become common topics to be studied in astrophysics, cosmology and particle physics.

 

So far a variety of researches on PBHs have been reported within a couple of years.  For students and young postdocs, it should have been a challenging task to catch up with recent topics related with PBHs. Therefore, we organize this school to study the current status of PBHs.

 

We ask each lecturer to cover both basic topics and cutting-edge researches. The number of audiences will be restricted due to the limited size of lecture rooms. The lecturers can use white boards as well as projectors, although we may ask the lecturers to mainly give white-board lectures, as these are easier for audiences to digest, in particular with regard to equations.

 

Topics to be discussed

1)     Mechanisms for Formations of PBHs

2)     Cosmological scenarios to produce PBHs

3)     Observational constraints on PBHs

4)     Astrophysical Black Holes
