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…
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…
Rotational Spectrum and First Interstellar Detection of 2-Methoxyethanol Using ALMA Observations of NGC 6334I
Zachary T. P. Fried, Samer J. El-Abd, Brian M. Hays +13
We use both chirped-pulse Fourier transform and frequency modulated absorption spectroscopy to study the rotational spectrum of 2-methoxyethanol in several frequency regions rangin…
Astrochemical Modeling of Propargyl Radical Chemistry in TMC-1
Alex N. Byrne, Ci Xue, Ilsa R. Cooke +2
Recent detections of aromatic species in dark molecular clouds suggest formation pathways may be efficient at very low temperatures and pressures, yet current astrochemical models…
Detection of Interstellar -1-cyano-1,3-butadiene in GOTHAM Observations of TMC-1
Ilsa R. Cooke, Ci Xue, P. Bryan Changala +12
We report the detection of the lowest energy conformer of -1-cyano-1,3-butadiene (-1-CHCN), a linear isomer of pyridine, using the fourth data reduction of the GOTHAM…
