Resolving the Interstellar Medium at the Peak of Cosmic Star Formation
, 2018 The interstellar medium feeds both the formation of stars and the growth of black holes, making it a key ingredient in the evolution of galaxies.

Molecular cooling in the diffuse interstellar medium [PDF]
, 2013 We use a simple one-zone model of the thermal and chemical evolution of interstellar gas to study whether molecular hydrogen (H2) is ever an important coolant of the warm, diffuse interstellar medium (ISM).

ChemPlusChem, EarlyView.The presence of interstellar complex organic molecules (COMs) has been baffling astrochemists for a long time. Methyl formate and glycolaldehyde are widely detected but their abundances mismatch kinetic astrochemical model predictions. Here, the formation of these two COMs is characterized onto a mixed ice surface, highlighting the importance of ...

SILICATE COMPOSITION OF THE INTERSTELLAR MEDIUM [PDF]
The Astrophysical Journal, 2016 ABSTRACT The composition of silicate dust in the diffuse interstellar medium and in protoplanetary disks around young stars informs our understanding of the processing and evolution of the dust grains leading up to planet formation. An analysis of the well-known 9.7 μm feature indicates that small amorphous silicate grains represent a ...

Metallicity Dependence of Molecular Cloud Hierarchical Structure at Early Evolutionary Stages
The Astrophysical Journal, 2023 The formation of molecular clouds out of H i gas is the first step toward star formation. Its metallicity dependence plays a key role in determining star formation throughout cosmic history.

Solid H2 in the interstellar medium
, 2018 Condensation of H 2 in the interstellar medium (ISM) has long been seen as a possibility, either by deposition on dust grains or thanks to a phase transition combined with self-gravity.

Kinetics and Thermodynamics of Tautomerization Reactions of 1,1‐ and 1,2‐Ethenediols
International Journal of Chemical Kinetics, EarlyView.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.

Mapping the interstellar medium in galaxies with Herschel/SPIRE [PDF]
, 2010 The standard method of mapping the interstellar medium in a galaxy, by observing the molecular gas in the CO 1-0 line and the atomic gas in the 21-cm line, is largely limited with current telescopes to galaxies in the nearby universe.

Panoramic Views of the Cygnus Loop [PDF]
, 1998 We present a complete atlas of the Cygnus Loop supernova remnant in the light of [O III] (5007), H alpha, and [S II] (6717, 6731). Despite its shell-like appearance, the Cygnus Loop is not a current example of a Sedov-Taylor blast wave.

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 ...
