A relativistic calculation of super-Hubble suppression of inflation with thermal dissipation
W. L. Lee, L. Z. Fang
We investigated the evolution of the primordial density perturbations produced by inflation with thermal dissipation. A full relativistic analysis on the evolution of initial pertu…
Intermittent behavior of cosmic mass field revealed by QSO's Ly_alpha forests
Priya Jamkhedkar, Hu Zhan, Li-Zhi Fang
The intermittent behavior of the space-scale distribution of Ly transmitted flux of QSO HS1700+64 has been analyzed via a discrete wavelet transform. We found that there are str…
Measuring the galaxy power spectrum and scale-scale correlations with multiresolution-decomposed covariance -- I. method
Li-Zhi Fang, Long-Long Feng
We present a method of measuring galaxy power spectrum based on the multiresolution analysis of the discrete wavelet transformation (DWT). Since the DWT representation has strong c…
Non-Gaussianity and the recovery of the mass power spectrum from the Ly forest
Long-Long Feng, Li-Zhi Fang
We investigate the effect of non-Gaussianity on the reconstruction of the initial mass field from the Ly forest. We show that the transmitted flux of QSO absorption spectra are…
