Molecular Clouds Resolved at the Onset of Cosmic Noon

The Astrophysical Journal Letters
We present the discovery of seven molecular clouds in the radio galaxy B2 0902+34 at redshift z = 3.4. These clouds are detected as CO(0–1) absorption features against the bright radio continuum and spectrally resolved using the Karl G. Jansky Very Large

3D MC. I. X-Ray Tomography Begins to Unravel the 3D Structure of a Molecular Cloud in our Galaxy’s Center

The Astrophysical Journal Letters
Astronomers have used observations of the Galactic gas and dust via infrared, microwave, and radio to study molecular clouds in extreme environments such as the Galactic center.

Velocity Structure and Molecular Formation in the Polaris Molecular Cloud

The Astrophysical Journal
We present a wide-field $(60^{\prime} \times 30^{\prime} )$ study of a dense region within the Polaris Flare using ^12 CO, ^13 CO, and C ^18 O ( J  = 1–0) observations at 15″ resolution, obtained with the Nobeyama 45 m Radio Telescope.

The Molecular Clouds of M31

The Astrophysical Journal
Deep interferometric observations of CO and dust continuum emission are obtained with the Submillimeter Array at 230 GHz to investigate the physical nature of the giant molecular cloud (GMC) population in the Andromeda galaxy (M31).

3D CMZ. III. Constraining the 3D Structure of the Central Molecular Zone via Molecular Line Emission and Absorption

The Astrophysical Journal
The Milky Way’s Central Molecular Zone (CMZ) is the largest concentration of dense molecular gas in the Galaxy, the structure of which is shaped by the complex interplay between Galactic-scale dynamics and extreme physical conditions.
