Research Abstract

Gravitational wave is the last method to observe the universe,and unique method to study black hole phenomena and the begging of the universe. However its signal is extremely weak and is hidden by various noises. Thus it is essential to get rid of noises for the detection of gravitaional waves. Min source of teh noise is the effect of large scale structure of the universe on the propagatioon of the gravitaional waves.
In this study I have developed a new method to describe large scale structure which is valid in nonlinera region and studied the effect of large scale structure on the distance redshift relation. We habe obtained the dispersion of the magnitude-redshift and showed the corret interpretation is not obtained without taking into account of teh dispersion.
