Surface features on interstellar ice

, 1996
Recent laboratory measurements of near-infrared features arising from dangling bonds at the surfaces of water ice are described. It is argued that the astronomical detection of these features will give a direct measurement of the surface: bulk ratio of ...

Astrochemistry of the Molecular Gas in Dusty Star-Forming Galaxies at the Cosmic Noon

Galaxies
Far-infrared and submillimeter observations have established the fundamental role of dust-obscured star formation in the assembly of stellar mass over the past ∼12 billion years.

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 ...

Metallic species in the interstellar medium: Astrochemical modeling

International audienceMetal-bearing species in diffuse or molecular clouds are often overlooked in astrochemical modeling except for the charge exchange process. However, catalytic cycles involving these metals can affect the abundance of other compounds.

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.
