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…

High Spectral Resolution Observations of Propynal (HCCCHO) towards TMC-1 from the GOTHAM Large Program on the Green Bank Telescope
Anthony J. Remijan, Zachary T. P. Fried, Ilsa R. Cooke +7
We used new high spectral resolution observations of propynal (HCCCHO) towards TMC-1 and in the laboratory to update the spectral line catalog available for transitions of HCCCHO -…
