Investigation of Hourglass-shaped Magnetic Fields in the G35.20–0.74 Star-forming Complex

The Astrophysical Journal
To investigate the role of magnetic fields toward the G35N and G35S subregions in the G35.20–0.74 star-forming complex, we utilized multiwavelength polarimetric observations from the SOFIA/HAWC+ at 154 μ m and Atacama Cosmology Telescope (ACT) at 220 GHz/

Star formation in infrared dark clouds: Self-gravity and dynamics

, 2016
The role played by gravity in the transfer of interstellar matter from molecular cloud scales to protostellar scales is still highly debated. Only detailed studies on the kinematics of large samples of star-forming clouds will settle the issue.

Revisiting a Chemical Route to the Formation of CN− in the Interstellar Medium

The Astrophysical Journal
We discuss the HCN + H ^− reaction as a path to the formation of CN ^− , the smallest cyanopolyyne anion observed in several interstellar environments.

Grains charges in interstellar clouds [PDF]

, 1989
The charge of cosmic grains could play an important role in many astrophysical phenomena. It probably has an influence on the coagulation of grains and more generally on grain-grain collisions, and on interaction between charged particles and grains ...

SPHEREx Widefield Infrared Spectral Mapping of Interstellar Ices and Polycyclic Aromatic Hydrocarbons

The Astrophysical Journal
We present some of the first infrared spectral maps acquired by SPHEREx. These maps, which to our knowledge are the largest of their type ever compiled in the near-infrared, reveal multiple strong lines due to interstellar ices and polycyclic aromatic ...

Revealing that the Gas-phase Reaction of CN with H2S Can Be a Source of HSCN in Interstellar Molecular Clouds

The Astrophysical Journal
Sulfur-bearing molecules are key constituents of the interstellar medium (ISM). Particularly, hydrogen sulfide (H _2 S) and cyano (CN) radicals are key precursors of prebiotic molecules in the ISM.

Velocities of magneto-elastic and magneto-electron waves in dark molecular clouds

, 2017
We present analytic and numerical estimates for group velocity of wave motions in two models of cold interstellar medium presumably constituting the interior of cores of magnetically supported dark molecular clouds.

UV radiation fields in dark clouds

How dark is it inside a dark cloud? If—as is currently believed-interstellar extinction at UV wavelengths is mainly due to scattering with a strongly forward throwing phase-function, the interior of a dark cloud may be much better illuminated at UV ...
