The galactic center environment
M Morris, E Serabyn�- Annual Review of Astronomy and�…, 1996 - annualreviews.org
▪ Abstract The central half kiloparsec region of our Galaxy harbors a variety of phenomena
unique to the central environment. This review discusses the observed structure and activity
of the interstellar medium in this region in terms of its inevitable inflow toward the center of
the Galactic gravitational potential well. A number of dissipative processes lead to a strong
concentration of gas into a “Central Molecular Zone” of about 200-pc radius, in which the
molecular medium is characterized by large densities, large velocity dispersions, high�…
