Measurement and Modeling of Polarized Atmosphere at the South Pole with SPT-3G

open access: yesThe Astrophysical Journal
We present the detection and characterization of fluctuations in linearly polarized emission from the atmosphere above the South Pole. These measurements make use of data from the SPT-3G receiver on the South Pole Telescope in three frequency bands ...

Sensitivity-improved Polarization Maps at 40 GHz with CLASS and WMAP Data

open access: yesThe Astrophysical Journal
Improved polarization measurements at frequencies below 70 GHz with degree-level angular resolution are crucial for advancing our understanding of the Galactic synchrotron radiation and the potential polarized anomalous microwave emission and ultimately ...

The Cosmic Microwave Background [PDF]

open access: yes, 2010
International audienceThe Cosmic Microwave Background (CMB) is one of the pillars on which the Big Bang theory relies. High-quality maps of this radiation strongly constrain the history of the Universe and its content.

[Cosmic Microwave Background (CMB) Anisotropies] [PDF]

open access: yes, 1998
One of the main areas of research is the theory of cosmic microwave background (CMB) anisotropies and analysis of CMB data. Using the four year COBE data we were able to improve existing constraints on global shear and vorticity.

CMBFSCNN: Cosmic Microwave Background Polarization Foreground Subtraction with a Convolutional Neural Network

open access: yesThe Astrophysical Journal Supplement Series
In our previous study, we introduced a machine learning technique, namely Cosmic Microwave Background Foreground Subtraction with Convolutional Neural Networks ( CMBFSCNN ), for the removal of foreground contamination in cosmic microwave background (CMB)

Primordial black holes in non-linear perturbation theory [PDF]

open access: yes, 2009
PhDThe thesis begins with a study of the origin of non-linear cosmological fluctuations. In particular, a class of models of multiple field inflation are considered, with specific reference to those cases in which the non-Gaussian correlation functions

WMAP: Fluctuations in the Cosmic Microwave Background [PDF]

open access: yes
This site discusses the cosmic microwave background, radiation left over from the Big Bang. Particular emphasis is upon tiny fluctuations in the temperature of the radiation, which are believed to reflect fluctuations in the density of matter in the ...
