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
Invited
speakers include:
Tomohiro Harada (Rikkyo
U, Japan), “Mechanisms for Formations of PBHs”
Teruaki Suyama (Tokyo Tech, Japan), “Cosmological formation rates
of binary PBHs”
Ryuichi
Takahashi (Hirosaki U, Japan), “Gravitational Lensing
and BHs”
Kohei Inayoshi (Peking U, China / Columbia U, USA), “Pop.III / II stars and binary BH formations”
