Koshiba Hall, The University of Tokyo, Hongo, Tokyo, Japan

Great advances have been made in the accuracy of cosmological and astrophysical observations in recent years and we are fortunate enough to live, for the first time, in an era of precision cosmology. We have made the startling discovery that the universe is currently entering a new phase of accelerated expansion, in addition to that hypothesized in the inflationary scenario, and the realization that we understand less than 5% of the contents of our universe has forged a new alliance between particle theorists, cosmologists and astronomers.

Dark energy, dark matter and the contents of the early universe are enigmas still to be solved, though the wealth of data at our disposal is greater than ever before. With the help of accurate CMB data from COBE and WMAP, a standard model of cosmology has emerged, but many questions remain unanswered and observational windows remain untapped.

Potentially one of the most significant of these is that of gravitational waves. The upcoming Planck experiment will allow us to probe the polarization spectrum of the surface of last scattering, which may allow for the indirect detection of gravitational waves through the discovery of B-modes. Direct detection in the not-too-distant future is now also a realistic possibility and the Japanese large cryogenic laser interferometer KAGRA, whose construction started this year, will undoubtedly be at the forefront of new discoveries.

Turning our eyes to the contemporary universe, we see that gravity plays an essential role in our understanding of many interesting astrophysical phenomena, such as the stellar lifecycle, gamma-ray bursts and supernovae, as well as in the behavior of galactic black holes, pulsars and binary systems. In addition, gravitational lensing observations, pioneered by astrophysicists, have attracted the attention of cosmologists and high-energy physicists alike and are one of the most promising tools in the effort to uncover the nature of dark energy.

This meeting aims to offer an overview of recent developments and new directions in research on gravitation, cosmology, and relativistic astrophysics, with special focus on future gravitational wave observations and the valuable insights into relativistic phenomena and the early history of the universe we may be able to infer from them.

The topics to be discussed include but are not limited to quantum gravity and creation of the universe, string cosmology, inflationary cosmology, the generation and evolution of density fluctuations, observational cosmology, gravitational lensing, primordial and astrophysical black holes, gamma-ray bursts, sources of gravitational radiation, gravitational wave experiments and modified gravity models.
