Description

Abstract:

Since the first detection of gravitational waves from coalescing binary black holes by LIGO in September 2015, we have entered an era of gravitational wave astronomy. Furthermore, a merger of binary neutron stars was detected for the first time in August 2017, and it was an unexpected happy surprise that the observation was made not only by gravitational waves but by electromagnetic waves with frequencies ranging from gamma rays to radio waves.

In addition to these tremendous achievements, a lot of efforts have been made toward detecting primordial gravitational waves coming from the very early universe. These developments will upgrade the current level of cosmology to an unprecedented level where gravitational waves will play an indispensable role, which I call "gravitational wave cosmology".

In this talk, I review the rapidly developing field of gravitational wave astronomy, and discuss current and future perspectives of gravitational wave cosmology.
