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…
