Strength Ratios of Diffuse Interstellar Bands in Slightly Reddened Objects
UniverseThe disk of the Milky Way fills the interstellar medium in the form of discrete clouds, many (∼30) light-years across. The average density of this medium is 1 hydrogen atom per cm3 (Oort limit), in the clouds—several dozen atoms, and between the clouds ...

Interstellar chemistry of nitrogen hydrides in dark clouds [PDF]
, 2013 Nitrogen, amongst the most abundant metals in the interstellar medium, has a peculiar chemistry that differs from those of carbon and oxygen. Recent observations of several nitrogen-bearing species in the interstellar medium suggest abundances in sharp ...

The Solar Galactic Environment
, 2004 Combined heliosphere-astronomical data and models enrich our understanding both of effects the solar galactic environment might have on the inner heliosphere, and of interstellar clouds.

A translated utopia: Embodied communication, media ideologies, and Star Trek's Universal Translator
Journal of Linguistic Anthropology, EarlyView.Abstract This paper uses Star Trek's “Universal Translator” (UT) as a point of departure for considering the imagined future of mediated linguistic interactions and of contact across difference. Although such a technology does not exist, taking its potentialities seriously as folkloric devices allows for an exploration of ideologies relating to ...

Boundary conditions for the paleoenvironment: Chemical and physical processes in the pre-solar nebula [PDF]
Detailed study of the first interstellar hydrocarbon ring, cyclopropenylidene (C3H2), is continuing. The singly deuterated isotope of this molecule, C3HD, was observed in several cold interstellar clouds.

Complex K: Supernova Origin of Anomalous-velocity H i Structure
The Astrophysical JournalWe address one of the lingering mysteries of high-velocity clouds: If the anomalous negative velocities are the result of the approaching gas from old supernovae, then where are the receding counterparts of the expanding shells?

Turbulence in the interstellar medium [PDF]
Nonlinear Processes in Geophysics, 2014 Turbulence is ubiquitous in the insterstellar medium and plays a major role in several processes such as the formation of dense structures and stars, the stability of molecular clouds, the amplification of magnetic fields, and the re-acceleration and ...

THE IMPLICATIONS OF A HIGH COSMIC-RAY IONIZATION RATE IN DIFFUSE INTERSTELLAR CLOUDS [PDF]
, 2009 Diffuse interstellar clouds show large abundances of H+3 which can only be maintained by a high ionization rate of H2. Cosmic rays are the dominant ionization mechanism in this environment, so the large ionization rate implies a high cosmic-ray flux, and

Photodissociation of OH in Interstellar Clouds
The Astrophysical Journal, 1984 Calculations are presented of the lifetime of OH against photodissociation by the interstellar radiation field as a function of depth into interstellar clouds containing grains of various scattering properties. The effectiveness of the different photodissociation channels changes with depth into a cloud. Absorption into the repulsive - state is usually
