The impact of hydrogen atom tunneling on aromatic chemistry in TMC-1

Reace H. J. Willis, Thomas H. Speak, Alex N. Byrne +2

Hydrogen atom tunneling likely plays a substantial role in the gas-phase chemistry of astrochemical environments. To determine the potential effect that it has on the chemical mode…

Modeling the Effect of C/O Ratio on Complex Carbon Chemistry in Cold Molecular Clouds

Alex N. Byrne, Christopher N. Shingledecker, Edwin A. Bergin +5

Elemental abundances, which are often depleted with respect to the solar values, are important input parameters for kinetic models of interstellar chemistry. In particular, the amo…

Detections of interstellar 2-cyanopyrene and 4-cyanopyrene in TMC-1

Gabi Wenzel, Thomas H. Speak, P. Bryan Changala +19

Polycyclic aromatic hydrocarbons (PAHs) are among the most ubiquitous compounds in the universe, accounting for up to ~25% of all interstellar carbon. Since most unsubstituted PAHs…

Discovery of interstellar 1-cyanopyrene: a four-ring polycyclic aromatic hydrocarbon in TMC-1

Gabi Wenzel, Ilsa R. Cooke, P. Bryan Changala +22

Polycyclic aromatic hydrocarbons (PAHs) are expected to be the most abundant class of organic molecules in space. Their interstellar lifecycle is not well understood, and progress…
