Mapping Our Path through the Local Interstellar Medium: High-resolution Ultraviolet Absorption Spectroscopy of Sight Lines along the Sun’s Historical Trajectory

The Astrophysical Journal
Using high-resolution UV data obtained from the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope, we focus on eight sight lines along the Sun’s historical trajectory to reconstruct the morphology of our most recent interstellar ...

Investigations of MWISP Bubbles: Identification and Analysis of Enclosed Molecular Bubbles by Weight Fields

The Astronomical Journal
Molecular bubbles are widely used as tracers of stellar feedback; yet, their identification in spectral-line surveys remains challenging because both cavity morphology and kinematic structure must be assessed consistently in position–position–velocity ...

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.

Grain Growth and Silicates in Dense Clouds

, 2006
Interstellar silicates are likely to be a part of all grains responsible for visual extinction (Av) in the diffuse interstellar medium (ISM) and dense clouds.

A sensitivity study of the neutral-neutral reactions C + C3 and C + C5 in cold dense interstellar clouds

, 2009
International audienceChemical networks used for models of interstellar clouds contain many reactions, some of them with poorly determined rate coefficients and/or products.
