The Sunyaev-Zel'dovich Effect by Cocoons of Radio Galaxies [PDF]

, 1999
We estimate the deformation of the cosmic microwave background radiation by the hot region (``cocoon'') around a radio galaxy. A simple model is adopted for cocoon evolution while the jet is on, and a model of evolution is constructed after the jet is ...

Dating the Middle Palaeolithic of Fumane Cave by the combined ESR/U‐series method

Journal of Quaternary Science, Volume 40, Issue 5, Page 862-875, July 2025.
ABSTRACT Fumane Cave, located in Northern Italy, is a major prehistoric site for understanding late Neandertal and early modern human behaviours. The cave contains a 12‐m‐thick stratigraphic sequence of Middle and Upper Palaeolithic layers, which have yielded a number of flint artefacts and faunal remains.

A Cosmic Microwave Background Radiation Polarimeter Using Superconducting Bearings

, 2003
Measurements of the polarization of the cosmic microwave background (CMB) radiation are expected to significantly increase our understanding of the early universe.

Nuclear Physics Meets the Sources of the Ultra-High Energy Cosmic Rays [PDF]

, 2016
The determination of the injection composition of cosmic ray nuclei within astrophysical sources requires sufficiently accurate descriptions of the source physics and the propagation - apart from controlling astrophysical uncertainties.

Geophysical tools for agricultural management: Trends, challenges, and opportunities

Vadose Zone Journal, Volume 24, Issue 4, July/August 2025.
Abstract Agrogeophysics is a convergence of proximal soil sensing and hydrogeophysics in which geophysical methods are used to describe soil patterns and dynamics that shape agronomic management (including precision agriculture). To fully realize its potential for optimizing agricultural production, current barriers and targets for future ...

Angular Spectra for non-Gaussian Isotropic Fields [PDF]

, 2013
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.

The speed of quantum information and the preferred frame: analysis of experimental data [PDF]

, 2000
The results of EPR experiments performed in Geneva are analyzed in the frame of the cosmic microwave background radiation, generally considered as a good candidate for playing the role of preferred frame.

WACCM Simulation of Polar Ozone Response to Relativistic Electron Precipitation

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Various studies have been dedicated to quantifying the atmospheric chemical effects of energetic electron precipitation (EEP), but the contribution from relativistic electron precipitation (REP) was largely overlooked. Based on the precipitating fluxes estimated from Polar‐orbiting Observational Environmental Satellites, we quantify the REP ...

Ultra-high energy cosmic rays threshold in Randers-Finsler space

, 2008
Kinematics in Finsler space is used to study the propagation of ultra high energy cosmic rays particles through the cosmic microwave background radiation. We find that the GZK threshold is lifted dramatically in Randers-Finsler space.

Cosmology and Astrophysical Constraints of Gauss-Bonnet Dark Energy [PDF]

, 2006
Cosmological consequences of a string-motivated dark energy scenario featuring a scalar field coupled to the Gauss-Bonnet invariant are investigated. We study the evolution of the universe in such a model, identifying its key properties. The evolution of
