CMB constraints on the early universe independent of late time cosmology

Autor: Pablo Lemos, Antony Lewis

The CMB is a powerful probe of early-universe physics but is only observed after passing through large-scale structure, which changes the observed spectra in important model-dependent ways. This is of particular concern given recent claims of signifi

Simons Observatory: Constraining inflationary gravitational waves with multitracer B -mode delensing

Publikováno v: Phys.Rev.D
Phys.Rev.D, 2022, 105 (2), pp.023511. ⟨10.1103/PhysRevD.105.023511⟩

Physical Review D, 105(2):023511. AMER PHYSICAL SOC

We introduce and validate a delensing framework for the Simons Observatory (SO), which will be used to improve constraints on inflationary gravitational waves (IGWs) by reducing the lensing noise in measurements of the $B$-modes in CMB polarization.

CMB lensing from Planck PR4 maps

Autor: Julien Carron, Mark Mirmelstein, Antony Lewis

We reconstruct the Cosmic Microwave Background (CMB) lensing potential on the latest Planck CMB PR4 (NPIPE) maps, which include slightly more data than the 2018 PR3 release, and implement quadratic estimators using more optimal filtering. We increase

Quadratic estimators for CMB weak lensing

Autor: Antony Lewis, Mathew S. Madhavacheril, Julien Carron, Yacine Ali-Haïmoud, Abhishek S. Maniyar

Publikováno v: Physical Review D. 103

In recent years, weak lensing of the cosmic microwave background (CMB) has emerged as a powerful tool to probe fundamental physics, such as neutrino masses, primordial non-Gaussianity, dark energy, and modified gravity. The prime target of CMB lensin

Lensed CMB power spectrum biases from masking extragalactic sources

Autor: Giulio Fabbian, Antony Lewis, Julien Carron, Margherita Lembo

Publikováno v: Physical Review D. 103

The cosmic microwave background (CMB) is gravitationally lensed by large-scale structure, which distorts observations of the primordial anisotropies in any given direction. Averaged over the sky, this important effect is routinely modelled with the l

CMB lensing reconstruction biases from masking extragalactic sources

Autor: Margherita Lembo, Giulio Fabbian, Julien Carron, Antony Lewis

Observed Cosmic Microwave Background (CMB) maps are contaminated by foregrounds, some of which are usually masked to perform cosmological analyses. If masks are correlated to the lensing signal, such as those removing extragalactic emissions located
