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…
The Molecular Inventory of TMC-1 with GOTHAM Observations
Ci Xue, Alex N. Byrne, Larry Morgan +14
Spectral line surveys of the Taurus Molecular Cloud-1 (TMC-1) have led to the detection of more than 100 new molecular species, making it the most prolific source of interstellar m…
Laboratory rotational spectra of cyanocyclohexane and its siblings (1- and 4-cyanocyclohexene) using a compact CP-FTMW spectrometer for interstellar detection
Gabi Wenzel, Martin S. Holdren, D. Archie Stewart +4
Chirped-pulse Fourier transform microwave (CP-FTMW) spectroscopy is a versatile technique to record broadband gas-phase rotational spectra, enabling detailed investigations of mole…
Discovery of the 7-ring PAH Cyanocoronene (CHCN) in GOTHAM Observations of TMC-1
Gabi Wenzel, Siyuan Gong, Ci Xue +18
We present the synthesis and laboratory rotational spectroscopy of the 7-ring polycyclic aromatic hydrocarbon (PAH) cyanocoronene (CHCN) using a laser-ablation assist…
Sensitivity Analysis of Aromatic Chemistry to Gas-Phase Kinetics in a Dark Molecular Cloud Model
Alex N. Byrne, Ci Xue, Troy Van Voorhis +1
The increasingly large number of complex organic molecules detected in the interstellar medium necessitates robust kinetic models that can be relied upon for investigating the invo…
