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

The 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 ...

Higgs field and cosmological parameters in the fractal quantum system

EPJ Web of Conferences, 2017
For the fractal model of the Universe the relations of cosmological parameters and the Higgs field are established. Estimates of the critical density, the expansion and speed-up parameters of the Universe (the Hubble constant and the cosmological ...

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

The 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 ...

On the cosmic microwave background radiation

, 2017
In this article we will try to give a pale idea to the reader of what could be the Cosmic Microwave Background (RCFM) that, according to the traditional Big Bang model, was generated by a primordial explosion. With this purpose we find it very important to present a brief historical summary of how the Microcosm, based on the Standard Model of ...

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

The 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)

Cosmic archeology with the Cosmic Microwave Background Radiation

, 2010
A cosmologia é uma ciência relativamente jovem, e que permanentemente requer observações que sustentem as previsões teóricas dos cientistas que trabalham nessa área. A Radiação Cósmica de Fundo em microondas (RCFM) é uma das observações utilizadas para isso, sendo a mais antiga fonte de observação direta do Universo de que dispomos e uma evidência ...

Supervised Extraction of the Thermal Sunyaev–Zel’dovich Effect with a Three-dimensional Convolutional Neural Network

The Astrophysical Journal
The thermal Sunyaev–Zel’dovich (SZ) effect offers a unique probe of the hot and diffuse Universe that could help close the missing baryon problem. Traditional extractions of the SZ effect, however, exhibit systematic noise that may lead to unreliable ...
