The growth of structure in the intergalactic medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2002 A {\it stochastic adhesion} model is introduced, with the purpose of describing the formation and evolution of mildly nonlinear structures, such as sheets and filaments, in the intergalactic medium (IGM), after hydrogen reionization. The model is based on replacing the overall force acting on the baryon fluid -- as it results from the composition of ...

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.

Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020 The two‐dimensional hydrogen atom in an external magnetic field is considered in the context of phase space. Using the solution of the Schrödinger equation in phase space, the Wigner function related to the Zeeman effect is calculated. For this purpose, the Bohlin mapping is used to transform the Coulomb potential into a harmonic oscillator problem ...

The Intergalactic Medium [PDF]
Highlights of Astronomy, 1980 Observations of Lyman-α absorption show that any gas present in the space between clusters of galaxies must be hot, and x-ray observations indicate that there may be present gas whose temperature at low redshifts is 4 × 108 K and whose density is about half the critical value for cosmology.

On galactic rotation and the intergalactic medium
, 1975 The observed spectrum of the isotropic diffuse X-ray background has often been invoked to infer the possible existence of a hot intergalactic medium at a density of the order of that required for closure of the Universe.
