Perspectives for Cosmological Reionization From Future CMB and Radio Projects
Frontiers in Astronomy and Space Sciences, 2018 In spite of the great recent results from the Planck satellite supporting cosmological reionization scenarios almost compatible with astrophysical models for the evolution of structure, galaxy and star formation, the full understanding of the ...

Photoelectron Spectroscopy of the Phosphorus Monosulfide (PS) and Phosphorus Monoxide (PO) Radicals
Small Structures, Volume 7, Issue 1, January 2026.Sketch of the experiment to measure the photo electron spectrum of the PS radical produced in situ with a mixture of PH3, H2S and F atoms. PO and PS radicals are the smallest units of phosphorus oxides and phosphorus sulfides, respectively, two rich families of refractory compounds widely employed in industrial and technological applications. These two

Imprints of quantum gravity in the cosmic microwave background
European Physical Journal C: Particles and Fields, 2019 It has been shown that the spectrum of quantum gravity contains at least two new modes in addition to the massless graviton: a massive spin-0 and a massive spin-2.

The Chinese Radio Telescope Array for Interplanetary Scintillation Monitoring
Space Weather, Volume 24, Issue 1, January 2026.Abstract Solar flares, coronal mass ejections (CMEs) and enegertic particles, etc., are the driving sources that may cause catastrophic space weathers. It is desirable to obtain information of solar eruptions like flares and CMEs, etc., propagating from the Sun to the near‐Earth space.

Simons Observatory: Characterization of the Large Aperture Telescope Receiver
The Astrophysical Journal Supplement SeriesThe Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) survey experiment that currently consists of three 0.42 m small-aperture telescopes and one 6 m large-aperture telescope (LAT), located at an elevation of 5200 m in the ...

Advances in Astronomy, Volume 2026, Issue 1, 2026.We examine the weak cosmic censorship conjecture (WCCC) violation by throwing a charged and rotating test particle into a Kerr–Newman–modified gravity black hole (KN–MOG BH). The result depends on several factors, such as the relative sign of the particle’s charge and its direction of rotation with respect to black hole (BH).

Polarization of the microwave background: Theoretical framework
, 1997 We present a brief review of the polarization properties of the cosmic microwave background in dark matter models for structure formation. Quite independently of the model parameters, the polarization level is expected to be similar to 10% Of the ...

The Observational Signatures of Cosmic Strings
, 2009 Cosmic strings were postulated by Kibble in 1976 and, from a theoretical point of view, their existence finds support in modern superstring theories, both in compactification models and in theories with extended additional dimensions.

Spectral Distortions of the Cosmic Microwave Background [PDF]
, 2005 Studying the cosmic microwave background (CMB) has proven to be an immensely rich source of information about the Universe we live in. Many groups were and are intensely working on the interpretation of the large amount of CMB data, which has become ...

Separation of Correlated Astrophysical Sources Using Multiple-Lag Data Covariance Matrices
EURASIP Journal on Advances in Signal Processing, 2005 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.
