Lyα Flux Power Spectrum and Its Covariance
We analyze the flux power spectrum and its covariance using simulated Lyα forests. We find that pseudo-hydro techniques are good approximations of hydrodynamical simulations at high redshift. However, the pseudo-hydro techniques fail at low redshift because they are insufficient for characterizing some components of the low-redshift intergalactic medium, notably the warm-hot intergalactic mediu...

متن کاملPower spectrum and Intermittency of the Transmitted Flux of QSOs’ Lyα Absorption Spectra
Using a set of 28 high resolution, high signal to noise ratio (S/N) QSO Lyα absorption spectra, we investigate the non-Gaussian features of the transmitted flux fluctuations, and their effect upon the power spectrum of this field. We find that the spatial distribution of the local power of the transmitted flux on scales k ≥ 0.05 s/km is highly spiky or intermittent. The probability distribution...
متن کاملPower Spectrum Super-Sample Covariance
We provide a simple, unified approach to describing the impact of super-sample covariance on power spectrum estimation in a finite-volume survey. For a wide range of survey volumes, the sample variance that arises from modes that are larger than the survey dominates the covariance of power spectrum estimators for modes much smaller than the survey. The perturbative and deeply nonlinear versions...
متن کاملPower Spectrum Covariance of Weak Gravitational Lensing
Weak gravitational lensing observations probe the spectrum and evolution of density fluctuations and the cosmological parameters which govern them. At low redshifts, the non-linear gravitational evolution of large scale structure produces a non-Gaussian covariance in the shear power spectrum measurements that affects their translation into cosmological parameters. Using the dark matter halo app...
