Angular Spectra for non-Gaussian Isotropic Fields [PDF]
Cosmic Microwave Background (CMB) Anisotropies is a subject of intensive research in several fields of sciences. In this paper we start a systematic development of basic notions and theory in statistics according to the application for CMB.

Exploring cosmic origins with CORE: Extragalactic sources in cosmic microwave background maps [PDF]
We discuss the potential of a next generation space-borne Cosmic Microwave Background (CMB) experiment for studies of extragalactic sources. Our analysis has particular bearing on the definition of the future space project, CORE, that has been submitted ...

Design of Waveguide NbN‐Based Superconductor–Insulator–Superconductor Mixer for 650 GHz
This research work focuses on a waveguide NbN‐based superconductor–insulator–superconductor mixer operating at 650 GHz. The signal coupling circuit is designed using a waveguide‐microstrip coupling structure, and the return loss obtained is lower than −16 dB. For the mixing circuit, its return loss is less than −7.5 dB, and the return loss reduces with

Cosmic Microwave Background Polarization Analysis [PDF]
With polarization of the cosmic microwave background (CMB) now detected, and confirmed by several independent experiments, the next goal is to characterise accurately its statistical properties. In these lecture notes we review the physical motivation for pursuing CMB polarization, and the basic statistical properties of the polarization fields.

Separation of Correlated Astrophysical Sources Using Multiple-Lag Data Covariance Matrices
This paper proposes a new strategy to separate astrophysical sources that are mutually correlated. This strategy is based on second-order statistics and exploits prior information about the possible structure of the mixing matrix.

Probing the statistic in the cosmic microwave background
Kolmogorov's statistic is used for the analysis of properties of perturbations in the Cosmic Microwave Background signal. We obtain the maps of the Kolmogorov stochasticity parameter for W and V band temperature data of WMAP which are differently ...

Cosmic Sculpture: A new way to visualise the Cosmic Microwave Background
3D printing presents an attractive alternative to visual representation of physical datasets such as astronomical images that can be used for research, outreach or teaching purposes, and is especially relevant to people with a visual disability.

Cosmic Microwave Background Radiation Anisotropy Induced by Cosmic Strings
We report on a current investigation of the anisotropy pattern induced by cosmic strings on the cosmic microwave background radiation (MBR). We have numerically evolved a network of cosmic strings from a redshift of $Z = 100$ to the present and ...
