Central Molecular Zone

The CMZ differs considerably from other large volumes of the Milky Way in terms of gas density, temperature, and turbulence.

Additionally, compared to the galactic disk, the CMZ produces a higher flux of cosmic rays and also emits copious ultraviolet and X-ray radiation.

Its highest gas surface densities are found east of the Milky Way's dynamical center at positive latitudes and velocities.

[5] The CMZ contains the Galactic Center Radio Arc various supernova remnants and emission nebulae.

[7] Concentrations of cold dust with diameters of approximately 0.1 to 0.65 light-years, which are likely progenitor cores of future star systems, number in at least the hundreds.
