Lyα emitters in a cosmological volume II: the impact of the intergalactic medium [PDF]
, 2020 In the near future galaxy surveys will target Lyman alpha emitting galaxies (LAEs) to unveil the nature of dark energy. It has been suggested that the observability of LAEs is coupled to the large scale properties of the intergalactic medium.

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 ...

Microquasars as heating sources of the intergalactic medium during reionization of the Universe [PDF]
, 2017 International audienceThe effect of the primeval sources of radiation and particles on the thermodynamical state of the intergalactic medium during the epoch of reionization is still unclear.

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.

PECULIARITIES OF MIXING METALS IN INTERGALACTIC AND INTERSTELLAR MEDIA
Odessa Astronomical Publications, 2008 We review the current status of the problem of metal mixing in the intergalactic and interstellar media. We give simple arguments for inefficiency of mixing metals because of a saturation of hydrodynamic (Rayleigh-Taylor and Kelvin-Helmholz ...

The Astrophysical JournalWe 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.

The THESEUS Space Mission and the Infrared Telescope Calibration Unit
Astronomische Nachrichten, Volume 347, Issue 6, July 2026.ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an

Galactic Winds in the Intergalactic Medium
The Astrophysical Journal, 2002 We have performed hydrodynamical simulations to investigate the effects of galactic winds on the high-redshift (z=3) universe. Strong winds suppress the formation of low-mass galaxies significantly, and the metals carried by them produce C IV absorption lines with properties in reasonable agreement with observations. The winds have little effect on the
