Relative Velocities between 13CO Structures within 12CO Molecular Clouds

The Astronomical Journal
Velocity fields of molecular clouds (MCs) can provide crucial information on the merger and split between clouds, as well as their internal kinematics and maintenance, energy injection and redistribution, and even star formation within clouds.

Structure and Fragmentation Scale of a Massive Star-forming Filament in NGC 6334: High-resolution Mid-infrared Absorption Imaging with JWST

The Astrophysical Journal Letters
Dense filaments are believed to be representative of the initial conditions of star formation in molecular clouds. We have used the MIRI instrument on JWST to image the massive filament NGC 6334M at d  ∼ 1.3 kpc with unprecedented resolution and dynamic ...

Variation in X_CO Factor in N55 Region

Universe
The XCO factor is defined as XCO=N(H2)/W12CO. It is useful for estimating cloud mass. However, there is only limited research on how the XCO factor varies within a single cloud.

Hierarchical Structure and Self-gravity in the Maddalena Giant Molecular Cloud

The Astrophysical Journal
In this work, we present data from the Milky Way Imaging Scroll Painting project for the Maddalena giant molecular cloud (GMC). We decompose the ^13 CO emission datacube of the observed region into hierarchical substructures using a modified dendrogram ...

Grain growth, optical polarisation, and extinction in interstellar clouds [PDF]

Increases in the wavelength of maximum polarization and the ratio of total to selective extinction are generally assumed to be the result of grain growth in interstellar clouds.
