THE RE‐DISCOVERY OF CONTEMPLATION THROUGH SCIENCE
Zygon®, Volume 56, Issue 3, Page 758-776, September 2021., 2021 Abstract Some of the early‐modern changes in the social framing of science, while often believed to be essential, are shown to be contingent. They contribute to the flawed public narrative around science today, and especially to the misconceptions around science and religion.

On the Electromagnetic Vacuum Origins of Dark Energy, Dark Matter, and Astrophysical Jets
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 We use a semiclassical version of the Nexus paradigm of quantum gravity in which the quantum vacuum at large scales is dominated by the second quantized electromagnetic field to demonstrate that a virtual photon field can affect the geometric evolution of Einstein manifolds or Ricci solitons.

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)

The Astrophysical Journal, 2023 This paper proposes a new method for estimating the total quantity of material in moving circumgalactic and intergalactic clouds from O vi measurements. We simulate high-velocity clouds (HVCs) with the FLASH hydrodynamic code and track the ionization and

The dark form of matter, on optical transmittance of ultra diluted gas
Results in Physics, 2020 The paper proposes a model of optical transmittance of ultra diluted gas taking into account gas particles non-locality, the quantum effect of wave function spreading derived from solving the Schrödinger equation for a free particle.

The future of galaxies and the fate of intelligent life [PDF]
Serbian Astronomical Journal, 1999 We investigate the influence of recent advances in research on the gaseous content of the universe on our knowledge of star formation histories of spiral galaxies.

Symposium - International Astronomical Union, 1974 Evidence that rich clusters of galaxies contain hot (T = 108 K) intracluster gas is reviewed. Such gas contributes little to Ω (0.003) but it has been argued that Ω must be less than 0.05 for true intergalactic gas, if accretion of more gas than is observed in rich clusters is to be avoided.

The Metallicity of Intergalactic Gas in Cosmic Voids [PDF]
The Astrophysical Journal, 2007 We have used the Hubble/STIS and FUSE archives of ultraviolet spectra of bright AGN to identify intergalactic Lya absorbers in nearby (z < 0.1) voids. From a parent sample of 651 Lya absorbers, we identified 61 void absorbers located more than 1.4/h_70 Mpc from the nearest L* or brighter galaxy.

How do atomic code uncertainties affect abundance measurements in the intracluster medium?
Astronomische Nachrichten, Volume 341, Issue 2, Page 203-209, February 2020., 2020 Abstract Accurate chemical abundance measurements of X‐ray‐emitting atmospheres pervading massive galaxies, galaxy groups, and clusters provide essential information on the star formation and chemical enrichment histories of these large‐scale structures.
