Baryons and weak lensing power spectra
We provide a simple toy model to elucidate the effects of baryonic cooling on predictions of the convergence power spectrum in weak gravitational lensing. Our model suggests that the effects of baryonic cooling on dark matter halo profiles can alter the dark matter power spectrum at k ∼ 10hMpc and lead to percent level changes in the convergence angular power spectrum at wavenumbers of several ...
متن کاملWeak lensing power spectra for precision cosmology
It is usually assumed that the ellipticity power spectrum measured in weak lensing observations can be expressed as an integral over the underlying matter power spectrum. This is true at order O(Φ2) in the gravitational potential. We extend the standard calculation, constructing all corrections to order O(Φ4). There are four types of corrections: corrections to the lensing shear due to multiple...
متن کاملPower Spectra Estimation for Weak Lensing
We develop a method for estimating the shear power spectra from weak lensing observations and test it on simulated data. Our method describes the shear field in terms of angular power spectra and cross correlation of the two shear modes which differ under parity transformations. Two of the three power spectra can be used to monitor unknown sources of noise in the data. The power spectra are dec...
متن کاملWeak Gravitational Lensing of High-redshift 21 Cm Power Spectra
We describe the effects of weak gravitational lensing by cosmological large scale structure on the diffuse emission of 21 centimeter radiation from neutral hydrogen at high redshifts during the era of reionization. The ability to observe radial information through the frequency, and thus threedimensional regions of the background radiation at different redshifts, suggests that 21 cm studies may...
متن کاملEffect of Hot Baryons on the Weak-lensing Shear Power Spectrum
We investigate the impact of the intracluster medium on the weak-lensing shear power spectrum. The shear power spectrum depends on the total mass power spectrum. With the halo model, we find that the baryon power spectrum is significantly lower than the dark matter power spectrum on scales well below the linear scale. The effect on the shear power spectrum is much less pronounced. Nevertheless,...
