Interstellar and Intergalactic Medium
2021This concise textbook, the first volume in the Ohio State Astrophysics Series, covers all aspects of the interstellar and intergalactic medium for graduate students and advanced undergraduates. This series aims to impart the essential knowledge on a topic that every astrophysics graduate student should know, without going into encyclopedic depth.

This chapter examines the intergalactic medium (IGM). Although much of astronomy focuses on the luminous material inside galaxies, the majority of matter today—and the vast majority at z > 6—actually lies outside these structures, in the IGM. This material ultimately provides the fuel for galaxy and cluster formation and—because it is much less ...

Small missions for energetic astrophysics, 1999
It is remarkable that a small space satellite mission can be created that has, potentially, the capability of detection of the dark matter of the universe, and in particular, detection of the intergalactic medium. I describe the approach for such a sample mission, and I also briefly comment on, and illustrate, black holes; black holes represent another

The fact that the process of galaxy formation must not necessarily be 100% efficient, raises the possibility that some portion of matter in the Universe lies in the intergalactic space. The aim of this seminar is to show that a hot electron - proton Intergalactic Medium (IGM) can exist, though some points are still unclear.

Baryons in the Diffuse Intergalactic Medium
Space Science Reviews, 2002The baryon density of the universe Ω B is well measured indirectly from Big-Bang nucleo-synthesis, in particular by recent measurements of the D/H ratio in high-redshift QSO absorption systems. In addition, very recent measurements of the second maximum of the power-spectrum of the CMB fine scale anisotropy allow to constrain Ω B at z ≈ 1000.

Metals in the Intergalactic Medium
Astrophysics and Space Science, 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 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.
