Cosmic-Ray Induced Diffusion in Interstellar Ices
Open Astronomy, 2014 Cosmic rays are able to heat interstellar dust grains. This may enhance molecule mobility in icy mantles that have accumulated on the grains in dark cloud cores.

Feeding vs Falling. The growth and collapse of molecular clouds in a turbulent interstellar medium
, 2017 In order to understand the origin of observed molecular cloud properties, it is critical to understand how clouds interact with their environments during their formation, growth and collapse.

Organic Molecules in Translucent Interstellar Clouds [PDF]
Origins of Life and Evolution of Biospheres, 2014 Absorption spectra of translucent interstellar clouds contain many known molecular bands of CN, CH+, CH, OH, OH(+), NH, C2 and C3. Moreover, one can observe more than 400 unidentified absorption features, known as diffuse interstellar bands (DIBs), commonly believed to be carried by complex, carbon-bearing molecules.

Multi-wavelength observations of a nearby multi-phase interstellar cloud
, 2008 Aims. High-resolution spectroscopic observations (UV HST/STIS and optical) are used to characterize the physical state and velocity structure of the multiphase interstellar medium seen towards the nearby (170 pc) star HD 102065.

Advection in photodissociation regions and its effects on the intensities of rotational lines of H(_2)O [PDF]
, 2008 A parameter based study has been carried out in order to investigate advection in photodissociation regions (PDRs) by using plane-parallel, semi-infinite assumption.
