Numerical simulations of the Warm-Hot Intergalactic Medium [PDF]

, 2008
In this paper we review the current predictions of numerical simulations for the origin and observability of the warm hot intergalactic medium (WHIM), the diffuse gas that contains up to 50 per cent of the baryons at z~0.

Systematic Bias in Ionizing Radiation Escape Fraction Measurements from Foreground Large-scale Structures

The Astrophysical Journal
We investigate the relationship between the Ly α forest transmission in the intergalactic medium (IGM) and the environmental density of galaxies, focusing on its implications for the measurement of ionizing radiation escape fractions.

Feasibility Study for Application of Digitized Henize Mt. Wilson Michigan Southern Sky Hα$$ \boldsymbol{\alpha} $$ Survey Low‐Dispersive Spectral Plates for Searches for Anomalous and Highly Redshifted Objects

Astronomische Nachrichten, EarlyView.
ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...

Observational Tests of Intergalactic Enrichment Models

, 2005
We summarize recent results assessing the carbon and silicon abundances of the intergalactic medium (IGM) using the `pixel optical depth' technique. We briefly discuss the implications of these results for models of intergalactic enrichment, focusing on ...

Analytical Description of the Distributions of Primary and Secondary Cosmogenic Particles

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
In this work, we present an analytical description of the energy distributions of primary and secondary cosmogenic particles on Earth in terms of parameters having clear physical meaning. A modified power law is assumed for energy distributions, incorporating terms such as energy loss/decay, which are effective at low energies, and a source term, which

Dynamical evolution of high velocity clouds in the intergalactic medium [PDF]

, 2002
HI observations of high-velocity clouds (HVCs) indicate, that they are interacting with their ambient medium. Even clouds located in the very outer Galactic halo or the intergalactic space seem to interact with their ambient medium.

Towards a Fregean psycholinguistics

Analytic Philosophy, Volume 66, Issue 3, Page 349-371, September 2025.
Abstract This paper is partly exegetical, partly systematic. I argue that Frege's account of what he called “colouring” contains some important insights on how communication is related to mental states such as mental images or emotions. I also show that the Fregean perspective is supported by current research in psycholinguistics and that a full ...

The Fractal Geometry of the Cosmic Web and Its Formation

Advances in Astronomy, Volume 2019, Issue 1, 2019., 2019
The cosmic web structure is studied with the concepts and methods of fractal geometry, employing the adhesion model of cosmological dynamics as a basic reference. The structures of matter clusters and cosmic voids in cosmological N‐body simulations or the Sloan Digital Sky Survey are elucidated by means of multifractal geometry.

Investigating Ionization in the Intergalactic Medium

The Astrophysical Journal
The intergalactic medium (IGM) contains >50% of the baryonic mass of the Universe, yet the mechanisms responsible for keeping the IGM ionized have not been fully explained.

Communicating tokenomics and monetary policy: A comparative analysis of real and virtual economies

International Journal of Finance &Economics, Volume 30, Issue 3, Page 2849-2866, July 2025.
Abstract This article investigates the economic governance of blockchain‐based virtual economies in the context of monetary policy. Focusing on tokenomics communication, we employ deductive and inductive approaches, applying real‐world monetary policy metrics and text mining frameworks. Our comparative analysis reveals that the tokenomics communication
