Strength Ratios of Diffuse Interstellar Bands in Slightly Reddened Objects

Universe
The disk of the Milky Way fills the interstellar medium in the form of discrete clouds, many (∼30) light-years across. The average density of this medium is 1 hydrogen atom per cm3 (Oort limit), in the clouds—several dozen atoms, and between the clouds ...

Interstellar clouds containing optically thick H2

The Astrophysical Journal, 1975
The theory of Black and Delgarno that the relative populations of the excited rotational levels of H2 can be understood in terms of cascading following absorption in the Lyman and Werner bands is employed to infer the gas densities and radiation fields within diffuse interstellar clouds containing H2 that is optically thin in those bands.

The Passage of the Solar System through the Edge of the Local Bubble

The Astrophysical Journal
The Sun moves through the interstellar medium (ISM) at a velocity of ∼19 pc Myr ^−1 , making the conditions outside the solar system vary with time over millions of years.

Cloud-cloud collisions in the interstellar medium

The Astrophysical Journal, 1980
Results are presented from time-dependent numerical simulations of cloud-cloud collisions in the interstellar medium. Special emphasis is placed on physically detailed models of cloud collisions. The numerical simulations include heating, cooling, thermal conductivity, self-gravity, and molecule formation; magnetic fields have been neglected.
