... In (low-density) interstellar thermal plasmas, the excitation of the n =3 level in Hydrogen and the ionization of atomic Hydrogen are intimately connected, and so at first sight we would expect that radiation in H б and in the thermal radio continuum ...
... Warm (10 K), ionizedhydrogen is a principal component of our Galaxy's interstellar medium, with a mass surface density approximately one third that of the H I, a vertical scale height nearly ten times that of the H I cloud layer, and a power budget equal ...
... Ionizedhydrogen emission from the galaxy shows an unresolved central source and a circumnuclear ring of enhanced star for mation which has a radius of approximately 600 parsecs. ...
