Modeling sulfur depletion in interstellar clouds [PDF]
Astronomy & Astrophysics, 2019 Context. The elemental depletion of interstellar sulfur from the gas phase has been a recurring challenge for astrochemical models. Observations show that sulfur remains relatively non-depleted with respect to its cosmic value throughout the diffuse and translucent stages of an interstellar molecular cloud, but its atomic and molecular gas-phase ...

Energy Dissipation in Interstellar Cloud Collisions [PDF]
, 1997 We present a study of the kinetic energy dissipation in interstellar cloud collisions. The main aim is to understand the dependence of the elasticity (defined as the ratio of the final to the initial kinetic energy of the clouds) on the velocity and mass

Observations of Multiphase, High-velocity, Shocked Gas in the Vela Supernova Remnant
The Astrophysical Journal, 2023 We present an analysis of high-resolution far-UV archival spectra obtained with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope of the star HD 75309, which probes high-velocity shocked gas in the Vela supernova remnant (SNR).

Evidence of a High Carbon Abundance in the Local Interstellar Cloud [PDF]
, 2006 The nature of the local interstellar cloud (LIC) is highly constrained by the combination of in situ heliospheric and line-of-sight data toward nearby stars.

Kinetics and Thermodynamics of Tautomerization Reactions of 1,1‐ and 1,2‐Ethenediols
International Journal of Chemical Kinetics, Volume 57, Issue 12, Page 687-696, December 2025.ABSTRACT Tautomerism is a common phenomenon amongst organic molecules with easily interconvertible isomers, which can impact drug action and toxicity. Here we are interested in the enols of carboxylic acids, which are known to be much less stable than their acid counterparts.

A modified theoretical Σ − D relation for supernova remnants: I. The case of constant temperature within the supernova remnant [PDF]
Serbian Astronomical Journal, 2003 We present a modification of the theoretical Σ − D relation for supernova remnants (SNRs) in the adiabatic expansion phase. This modification is based on the convolution of the relation first derived by Shklovsky with the Σ − D relation derived in this ...

The mass spectrum of interstellar clouds [PDF]
International Astronomical Union Colloquium, 1989 AbstractThe abundance of 21-cm absorption lines seen in surveys at high latitudes can be translated into a line of sight abundance of clouds vs. column density using an empirical relationship between temperature and optical depth. As VLA surveys of 21-cm absorption at low latitudes are now becoming available, it is possible to study the variation of ...

Interstellar cloud structure: the statistics of centroid velocities [PDF]
, 2006 Context. The statistical properties of maps of line centroids have been used for almost 50 years, but there is still no general agreement on their interpretation. Aims.

A translated utopia: Embodied communication, media ideologies, and Star Trek's Universal Translator
Journal of Linguistic Anthropology, Volume 35, Issue 3, December 2025.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 ...
