Intergalactic Medium

(IGM)
(matter between galaxies)

The Intergalactic Medium (IGM) is matter such as Dust and gas between galaxies. Similar matter between stars within a galaxy is called the Interstellar Medium. Between galaxies it is often Plasma in filaments, mostly ionized Hydrogen.

The IGM can heat to 105 to 107 K, called the warm-hot intergalactic medium (WHIM), observed in Ultraviolet and low-energy X-ray radiation.

The Intracluster Medium has a similar meaning, but more specifically means the medium within a Galaxy Cluster.
