First astronomical detection of the CF+ ion

, 2005
We report the first astronomical detection of the CF+ (fluoromethylidynium) ion obtained by recent observations of its J = 1 - 0 (102.6 GHz), J = 2 - 1 (205.2 GHz), and J = 3 - 2 (307.7 GHz) pure rotational emissions toward the Orion Bar.

Neutrals Ejected From Io's Plasma/Atmosphere Interaction Region by Physical Chemistry Processes

Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.
Abstract Neutrals ejected from Io's atmosphere are the source of many important structures of the jovian magnetosphere: they feed giant neutral clouds, which extend along Io's orbit and nebulae, which extend beyond 500 jovian radii. The neutral loss rate is casually claimed to be ∼1 ton/s, but the processes leading to this loss, their quantitative ...

Water Vapor in the Inner 25 AU of a Young Disk around a Low-Mass Protostar

, 2010
Water is one of the key molecules in the physical and chemical evolution of star- and planet-forming regions. We here report the first spatially resolved observation of thermal emission of (an isotopologue of) water with the Plateau de Bure ...

Molecular Astrophysics & Astrochemistry

, 2019
Many of the facilities and missions that Canada is or will be involved in as well as the diverse science programs that drive these missions rely on the astronomical detection and characterization of atomic and molecular gas as well as dust grains across the electromagnetic spectrum.

Mapping adsorption on ionic surfaces via a pairwise potential‐based high‐throughput approach

Journal of Applied Crystallography, Volume 58, Issue 4, Page 1462-1468, August 2025.
This work presents a high‐throughput method for predicting molecular adsorption sites on ionic surfaces using pairwise Coulomb and Lennard–Jones potentials. Requiring only a CIF as input, the approach enables rapid identification of stable adsorption structures, offering an efficient pathway for studying complex surface–adsorbate interactions ...

Proton and Electron Irradiations of CH₄:H₂O Mixed Ices

Atoms, 2023
The organic chemistry occurring in interstellar environments may lead to the production of complex molecules that are relevant to the emergence of life. Therefore, in order to understand the origins of life itself, it is necessary to probe the chemistry ...

Nature's Starships II: Simulating the Synthesis of Amino Acids in Meteorite Parent Bodies

, 2015
Carbonaceous chondrite meteorites are known for having high water and organic material contents, including amino acids. Here we address the origin of amino acids in the warm interiors of their parent bodies (planetesimals) within a few million years of ...

Laboratory Photo-chemistry of PAHs: Ionization versus Fragmentation [PDF]

, 2015
Interstellar polycyclic aromatic hydrocarbons (PAHs) are expected to be strongly processed by vacuum ultraviolet photons. Here, we report experimental studies on the ionization and fragmentation of coronene (C24H12), ovalene (C32H14) and hexa-peri ...
