Title: Double Compact Objects in Universe
Date (JST): Thu, May 06, 2010, 13:30 - 14:30
Place: Seminar Room A
Abstract: Double compact objects (NS-NS/BH-NS/BH-BH) are important sources for high energy emission (e.g., Gamma Ray Bursts) and for generation of high frequency gravitational waves. I will present known observational data on double compact objects and on their potential known progenitors. Since not much empirical data is available, I will also present theoretical predictions for formation of double compact objects and their subsequent mergers in local (e.g. Milky Way) and high-redshift Universe. The consequences of these predictions are of importance for currently operating gravitational wave observatories (LIGO/VIRGO) and may help in design of near-future missions (DECIGO, Einstein Telescope). I will also discuss the best "bets" for the first gravitational wave detection, its near-future chances and what can be actually learned with the first
gravitational radiation signal.
