Exploring the Limits of Spectral Line Stacking in Spectral Line Data and Application Toward the Detection of Bulk C Enrichment of Aromatics in TMC-1
Miya Duffy, Ryan A. Loomis, Martin S. Holdren +9
The paper evaluates spectral line stacking and matched‑filter techniques to detect faint 13C‑substituted aromatic molecules in the cold cloud TMC‑1, demonstrating the method’s abil…
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…
Rotational Spectra and Search for Aromatic Imines: 9-Iminofluorene and Benzophenone imine
Huanyu Ren, D. Archie Stewart, Gabi Wenzel +4
Interstellar detections of several cyano derivatives of large polycyclic aromatic hydrocarbons (PAHs) have now been achieved, enabled by accurate laboratory measurements of their m…
Rotational Spectroscopy and Tentative Interstellar Detection of 3-Hydroxypropanal (HOCHCHCHO) in the G+0.693-0.027 Molecular Cloud
Zachary T. P. Fried, Roman A. Motiyenko, Miguel Sanz-Novo +12
We synthesized the astrochemically relevant molecule 3-hydroxypropanal (HOCHCHCHO) and subsequently measured and analyzed its rotational spectrum in several frequency regio…
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…
