Generative Models of Multichannel Data from a Single Example—Application to Dust Emission
The Astrophysical Journal, 2023 The quest for primordial B -modes in the cosmic microwave background has emphasized the need for refined models of the Galactic dust foreground. Here we aim at building a realistic statistical model of the multifrequency dust emission from a single ...

Future Prospects on Constraining Neutrino Cosmology with the Ali CMB Polarization Telescope
The Astrophysical Journal, 2023 We forecast the constraints on the parameters of neutrino physics with the constructions of Cosmic Microwave Background (CMB) temperature, E-mode polarization, and lensing spectra for the ground-based Ali Cosmic Microwave Background Polarization ...

Testing Cosmic Microwave Background Anomalies in E-mode Polarization with Current and Future Data
The Astrophysical Journal, 2023 In this paper, we explore the power of the cosmic microwave background (CMB) polarization ( E -mode) data to corroborate four potential anomalies in CMB temperature data: the lack of large angular-scale correlations, the alignment of the quadrupole and ...

The cosmic microwave background radiation fluctuations from H i perturbations prior to reionization [PDF]
, 2004 Loeb and Zaldarriaga have recently proposed that observations of the cosmic microwave background radiation (CMBR) brightness temperature fluctuations produced by H I inhomogeneities prior to reionization hold the promise of probing the primordial power ...

Constraints on nonconformal couplings from the properties of the cosmic microwave background radiation. [PDF]
Physical Review Letters, 2013 Certain modified gravity theories predict the existence of an additional, nonconformally coupled scalar field. A disformal coupling of the field to the cosmic microwave background (CMB) is shown to affect the evolution of the energy density in the ...

THE COSMIC MICROWAVE BACKGROUND RADIATION* [PDF]
Annals of the New York Academy of Sciences, 1981 Because angular anisotropies and spectral distortions of the cosmic microwave background radiation are judged to be inevitable at some level, in a realistic cosmological model, the evidence for spectral distortions and its theoretical implications are described.

Partial Ly α thermalization in an analytic nonlinear diffusion model. [PDF]
Sci RepDuring recombination, the cosmic background radiation is disturbed, in particular, by Lyman-alpha emissions from neutral hydrogen. It is proposed to account for the subsequent time-dependent partial thermalization of the Ly $$\alpha$$ α energy content in
