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 ...

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.

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 ...

Long-range correlation in cosmic microwave background radiation [PDF]
Physical Review E, 2011 We investigate the statistical anisotropy and Gaussianity of temperature fluctuations of Cosmic Microwave Background radiation (CMB) data from {\it Wilkinson Microwave Anisotropy Probe} survey, using the multifractal detrended fluctuation analysis, rescaled range and scaled windowed variance methods.

The SPIDER CMB Polarimeter [PDF]
, 2012 SPIDER is a balloon-borne millimeter-wave telescope designed to study the polarization of the Cosmic Microwave Background (CMB). SPIDER will map 10% of the full sky with degree-scale beams to search for the distinctive inflationary gravitational wave ...

Estimating parameters of fluctuations in the cosmic microwave background [PDF]
, 1995 We address questions that arise in statistical analyses of recently detected fluctuations in the Cosmic Microwave Background (CMB). Estimators of the quadrupole amplitude, Q, and spectral index, n, of the CMB angular fluctuation power spectrum are ...

CMB as a Probe of New Physics and Old Times [PDF]
, 2013 Cosmic birefringence (CB)---a rotation of photon-polarization plane in vacuum---is a generic signature of new scalar fields that could provide dark energy. Previously, WMAP observations excluded a uniform CB-rotation angle larger than a degree.
