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…

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…

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…

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…
