Interstellar medium of external galaxies

Disentangling the contribution of each of the phases to the energy budget of the medium is made possible in external galaxies for which global measurements can be achieved.

Quasars absorption lines

Studies of diffuse gas at cosmological distances have been performed by analysing the UV spectra of quasars and deep high resolution images of quasar fields obtained with the Hubble Space Telescope spectra.
