Automated Assignment and Prediction of Molecules in Astronomical Line Surveys Using Machine-Learning-Based Chemical Embeddings
Zachary T. P. Fried, Ryan A. Loomis, Jes K. Jørgensen +6
Modern radio telescopes generate vast amounts of observational data, offering valuable insights into the molecular composition of interstellar sources. Identifying the molecules wi…
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 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…
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 -…
Astrochemical Modeling of Propargyl Radical Chemistry in TMC-1
Alex N. Byrne, Ci Xue, Ilsa R. Cooke +2
Recent detections of aromatic species in dark molecular clouds suggest formation pathways may be efficient at very low temperatures and pressures, yet current astrochemical models…
