The Central Molecular Zone or CMZ is a region of the Milky Way Galaxy rich in an estimated 60 million solar masses (M ☉) of gas within a complex of giant molecular clouds. [1] It spans the centre of the Milky Way, and as such is in the Sagittarius constellation, between galactic longitude 1.7° and -0.7°, and latitudes -0.2° and +0.2°.

Feb 29, 2016 · It contains almost eighty percent of all the dense gas in the galaxy - a reservoir of tens of millions of solar masses of material - and hosts giant molecular clouds and massive star forming...

Oct 22, 2024 · The Central Molecular Zone (CMZ) is the largest reservoir of dense molecular gas in the Galaxy and is heavily obscured in the optical and near-IR. We present an overview of the far-IR dust...

Feb 29, 2016 · New research confirms that the Milky Way's Central Molecular Zone is not centered on the black hole, but is offset; they also confirm that the gas motions throughout are supersonic. The center of our Milky Way galaxy lies about 27,000 light-years away in the direction of the constellation of Sagi.

We report the physical properties (molecular gas column density, N (H2), Tdust, mass, radius), kinematic properties (HNCO, HCN, and HC3N simple moment analysis), luminosity and star formation rates (SFRs) for each structure in the catalog.

Mar 21, 2022 · The Central Molecular Zone (CMZ) is a ring-like accumulation of molecular gas in the innermost few hundred parsecs of the Milky Way, generated by the inward transport of matter driven by the Galactic bar. The CMZ is the most extreme star-forming environment in the Galaxy.

Mar 15, 2024 · In the heart of the Milky Way exists a region called the central molecular zone, which is packed with an estimated 60 million solar masses of dust. This vast reservoir of dust has a temperature...

The central molecular zone (CMZ) is shown to be embedded in the HI disc (central HI zone, CHZ) of radius ∼320 pc and vertical scale height ∼70 pc. A radio continuum belt is shown to run parallel to molecular Arms I and II. The belt draws a double infinity (∞∞) on the sky, connecting Sgr E (l ∼−1 .2), C, B1, B2 and Sgr D (+1 .2), and

The central ~500pc of the Milky Way, the center being marked by the supermassive black hole Sgr A *, is called the Central Molecular Zone (CMZ) due to the large amounts of molecular gas found there.
