Weak Lensing of the Primary CMB Bispectrum
Asantha Cooray, Devdeep Sarkar, Paolo Serra
The cosmic microwave background (CMB) bispectrum is a well-known probe of the non-Gaussianity of primordial perturbations. Just as the intervening large-scale structure modifies th…
Cosmic Shear from Scalar-Induced Gravitational Waves
Devdeep Sarkar, Paolo Serra, Asantha Cooray +2
Weak gravitational lensing by foreground density perturbations generates a gradient mode in the shear of background images. In contrast, cosmological tensor perturbations induce a…
Lensing and Supernovae: Quantifying The Bias on the Dark Energy Equation of State
Devdeep Sarkar, Alexandre Amblard, Daniel E. Holz +1
The gravitational magnification and demagnification of Type Ia supernovae (SNe) modify their positions on the Hubble diagram, shifting the distance estimates from the underlying lu…
