Relic Gravitational Waves and Cmb Polarization in the Accelerating Universe
In this paper we briefly present our works on the relic gravitational waves (RGW) and the CMB polarization in the accelerating universe. The spectrum of RGW has been obtained, showing the influence of the dark energy. Compared with those from non-accelerating models, the shape of the spectrum is approximately similar, nevertheless, the amplitude of RGW now acquires a suppressing factor of the r...

متن کاملAnalytic approach to the CMB polarizations generated by relic gravitational waves
By Polnarev’s method we analytically calculate the polarization spectra of the cosmic microwave background radiation (CMB) generated by cosmic relic gravitational waves (RGW). In this analytic approach the physics involved in this generating process is more transparent. Consequently, the effects due to various elements of physics can be isolated easily. In solving the equation for evolution of ...
متن کاملAn Analytic Approach to the CMB Polarization Generated by Relic Gravitational Waves
We develop Polnarev’s analytic method to calculate of the polarization power spectrum of the cosmic microwave background radiation (CMB) generated by cosmic relic gravitational waves. In this analytic approach the physics involved in this process is more transparent. Consequently, the effects due to various elements of physics can be isolated easily. In numerically calculating the evolution of ...
متن کاملRelic Gravitational Waves and the Detection
As the “smoking-gun” evidence for inflation, the relic gravitational waves (RGW) have been studied by a lot of authors. Although, it hasn’t been detected until now, some constraints have been achieved by the observations. Future experiments for the RGW detection are mainly two kinds: the CMB (cosmic microwave background radiation) experiments and the laser interferometers. In this paper, we stu...
