Galactic Winds [PDF]

, 2005
Galactic winds are the primary mechanism by which energy and metals are recycled in galaxies and are deposited into the intergalactic medium. New observations are revealing the ubiquity of this process, particularly at high redshift.

Lower Metal Enrichment of Virialized Gas in Minihalos [PDF]

, 2007
We differentiate between the metal enrichment of the gas in virialized minihalos and that of the intergalactic medium at high redshift, pertinent to cosmological reionization, with the initial expectation that gas in the high density regions within ...

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.

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.

An Exploration of AGN and Stellar Feedback Effects in the Intergalactic Medium via the Low-redshift Lyα Forest

The Astronomical Journal, 2023
We explore the role of galactic feedback on the low-redshift Ly α (Ly α ) forest ( z ≲ 2) statistics and its potential to alter the thermal state of the intergalactic medium. Using the Cosmology and Astrophysics with Machine Learning Simulations (CAMELS)

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

Gamma‐Ray Burst Prompt Correlations

Advances in Astronomy, Volume 2018, Issue 1, 2018., 2018
The mechanism responsible for the prompt emission of gamma‐ray bursts (GRBs) is still a debated issue. The prompt phase‐related GRB correlations can allow discriminating among the most plausible theoretical models explaining this emission. We present an overview of the observational two‐parameter correlations, their physical interpretations, and their ...

Directly Tracing Cool Filamentary Accretion over >100 kpc into the Interstellar Medium of a Quasar Host at z = 1

The Astrophysical Journal Letters, 2022
We report the discovery of giant (50−100 kpc) [O ii ] emitting nebulae with MUSE in the field of TXS 0206−048, a luminous quasar at z = 1.13. “Down-the-barrel” UV spectra of the quasar show absorption at velocities coincident with those of the extended ...

Equilibration processes in the Warm-Hot Intergalactic Medium

, 2008
The Warm-Hot Intergalactic Medium (WHIM) is thought to contribute about 40-50 % to the baryonic budget at the present evolution stage of the universe. The observed large scale structure is likely to be due to gravitational growth of density fluctuations ...
