CMB-S4 forecasts for constraints on f NL through μ -distortion anisotropy

David Zegeye, F. Bianchini, J. Richard Bond, Jens Chluba et autres

Diffusion damping of the cosmic microwave background (CMB) power spectrum results from imperfect photon-baryon coupling in the pre-recombination plasma. Energy release at redshifts $5\ifmmode\times\else\texttimes\fi{}{10}^{4}<z<2\ifmmode\times\else\texttimes\fi{}{10}^{6}$ can create $\ensuremath{\mu}$-type spectral distortions of the CMB. These $\ensuremath{\mu}$ distortions trace the underlying photon density fluctuations, probing …

Cosmology with the Laser Interferometer Space Antenna

Pierre Auclair, David Bacon, Tessa Baker, Tiago Barreiro et autres

Abstract The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications for early universe and particle physics, from the MeV to the …

CMB-S4: Forecasting Constraints on $f_\mathrm{NL}$ Through $μ$-distortion Anisotropy

David Zegeye, F. Bianchini, J. Richard Bond, Jens Chluba et autres

Diffusion damping of the cosmic microwave background (CMB) power spectrum results from imperfect photon-baryon coupling in the pre-recombination plasma. At redshift $5 \times 10^4 < z < 2 \times 10^6$, the plasma acquires an effective chemical potential, and energy injections from acoustic …

Probing parity-odd bispectra with anisotropies of GW V modes

Giorgio Orlando

Abstract It is well known that non-trivial squeezed tensor bispectra can lead to anisotropies in the inflationary stochastic gravitational wave (GW) background, providing us with an alternative and complementary window to primordial non-Gaussianities (NGs) with respect to the CMB. Previous works have …

The reconstructed CMB lensing bispectrum

Alba Kalaja, Giorgio Orlando, Aleksandr Bowkis, A. Challinor et autres

Weak gravitational lensing by the intervening large-scale structure (LSS) of the Universe is the leading non-linear effect on the anisotropies of the cosmic microwave background (CMB). The integrated line-of-sight mass that causes the distortion -- known as lensing convergence -- can be …
