Galaxies are ecosystems consisting of dark matter, stars and gas. It is useful to split the gas into three broad components according to its relation to the galaxy. The first is the interstellar medium (ISM), which is the gas that is directly associated with the galaxy.

The dynamics of the intergalactic medium
Astrophysics and Space Science, 1982It is assumed that the intergalactic medium contains fully ionized plasmas. A detailed discussion shows that it is necessary to distinguish between medium-density and low-density plasmas before we can carry out any analysis. The conditions are very critical for the conclusions and application of any mechanism one likes to discuss for the intergalactic ...

Metals in the Intergalactic Medium
2001The absorption lines seen in the spectra of quasars trace gas over a very large range of over densities, from galaxies to voids and probably account for most of the baryons at high redshift. Once thought to be a chemically pristine remnant of the Big Bang, the Lyman alpha forest has now been shown to contain significant quantities of metals.

The Intergalactic Medium as a Cosmological Tool
Nuclear Physics B - Proceedings Supplements, 2009In this talk I will review the capabilities of high-resolution (UVES and Keck) and low resolution (Sloan Digital Sky Survey – SDSS) quasar (QSO) Lyman-α absorption spectra as cosmological tools to probe the dark matter distribution in the high redshift universe.

A critical review of the possible existence of a hot (T≥ l08 K) diffuse intergalactic medium (IGM) is given. Attention is paid to three main issues: its contribution to the X-ray background (XRB) by bremsstrahlung radiation, the Compton upscattering of the microwave background radiation (MBR) and the degree of dumpiness of the IGM. It is concluded that

The Intergalactic Medium Family
2019We now move into the Family of the intergalactic medium, consisting of both gas and dust. Intergalactic gas is a hot, highly rarefied plasma consisting primarily of ionized hydrogen, along with traces of other elements such as helium and oxygen. It has been detected at temperatures ranging from 300,000 to five million degrees Celsius.
