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 paper evaluates spectral line stacking and matched‑filter techniques to detect faint 13C‑substituted aromatic molecules in the cold cloud TMC‑1, demonstrating the method’s abil…
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…
CoCCoA: Complex Chemistry in hot Cores with ALMA. The chemical evolution of acetone from ice to gas
Y. Chen, R. T. Garrod, M. Rachid +5
Acetone (CH3COCH3) is one of the most abundant three-carbon oxygen-bearing complex organic molecules (O-COMs) that have been detected in space. Recently, acetone ice has been repor…
