Does Topology-Dependent Chemistry Influence the Interstellar PAH Inventory? Insights from the Absence of Cyanotriphenylenes
Huanyu Ren, Gabi Wenzel, Thomas H. Speak +8
Although a set of polycyclic aromatic hydrocarbons (PAHs) has recently been identified in the cold dark cloud TMC-1, several common PAH motifs remain absent, leaving the origin of…
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 formation history of polycyclic aromatic hydrocarbons (PAHs) in the interstellar medium remains a topic of active debate, with proposed mechanisms ranging from high-temperature…
Detection of the Polycyclic Aromatic Hydrocarbon Phenalene (CH) in the Very Low Luminosity Object (VeLLO) MC27/L1521F
Gabi Wenzel, Thomas H. Speak, Ci Xue +12
To date, 14 polycyclic aromatic hydrocarbons (PAHs) ranging in size from two to seven (including five- and six-membered) carbon rings have been detected in the starless dense core…
The Missing Link of Sulfur Chemistry in TMC-1: The Detection of c-C3H2S from the GOTHAM Survey
Anthony J. Remijan, P. Bryan Changala, Ci Xue +13
We present the spectroscopic characterization of cyclopropenethione (c-C3H2S) in the laboratory and detect it in space using the Green Bank Telescope (GBT) Observations of TMC-1: H…
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…
