Weak lensing of the CMB
The cosmic microwave background (CMB) represents a unique source for the study of gravitational lensing. It is extended across the entire sky, partially polarized, located at the extreme distance of…
Lensing of 21-cm fluctuations by primordial gravitational waves.
TLDR
Weak-gravitational-lensing distortions to the intensity pattern of 21-cm radiation from the dark ages can be decomposed geometrically into curl and curl-free components, allowing tensor-to-scalar ratios conceivably as small as r~10(-9)-far smaller than those currently accessible-to be probed.
Detection of gravitational lensing in the cosmic microwave background
Gravitational lensing of the cosmic microwave background (CMB), a long-standing prediction of the standard cosmological model, is ultimately expected to be an important source of cosmological…
WEAK GRAVITATIONAL LENSING OF THE COSMIC MICROWAVE BACKGROUND REVISITED
In this paper, we revisit the weak gravitational lensing of the cosmic microwave background (CMB). The key point is that the deflection angle of CMB photons varies with the redshift. From this we…
A Large Sky Simulation of the Gravitational Lensing of the Cosmic Microwave Background
Large-scale structure deflects cosmic microwave background (CMB) photons. Since large angular scales in the large-scale structure contribute significantly to the gravitational lensing effect, a…
CMB Lensing Constraints on Neutrinos and Dark Energy
Signatures of lensing of the cosmic microwave background radiation by gravitational potentials along the line of sight carry with them information on the matter distribution, neutrino masses, and…
3D weak gravitational lensing of the CMB and galaxies
In this paper we present a power spectrum formalism that combines the full three-dimensional information from the galaxy ellipticity field, with information from the cosmic microwave background…
Cosmic shear from scalar-induced gravitational waves
Weak gravitational lensing by foreground density perturbations generates a gradient mode in the shear of background images. In contrast, cosmological tensor perturbations induce a nonzero curl mode…
CMBR weak lensing and HI 21-cm cross-correlation angular power spectrum
Weak gravitational lensing of the CMBR manifests as a secondary anisotropy in the temperature maps. The effect, quantified through the shear and convergence fields imprint the underlying large scale…
Gravitational lensing of the cosmic neutrino background
We study gravitational lensing of the cosmic neutrino background. This signal is undetectable for the foreseeable future, but there is a rich trove of information available. At least some of the…
