An Automated Chemical Exploration of NGC 6334I at 340 au Resolution
Samer J. El-Abd, Crystal L. Brogan, Todd R. Hunter +3
Much of the information gleaned from observations of star-forming regions comes from the analysis of their molecular emission spectra, particularly in the radio regime. The time-co…
Explaining the Chemical Inventory of Orion KL through Machine Learning
Haley N. Scolati, Anthony J. Remijan, Eric Herbst +2
The interplay of the chemistry and physics that exists within astrochemically relevant sources can only be fully appreciated if we can gain a holistic understanding of their chemic…
A Search for Heterocycles in GOTHAM Observations of TMC-1
Timothy J. Barnum, Mark A. Siebert, Kin Long Kelvin Lee +9
We have conducted an extensive search for nitrogen-, oxygen- and sulfur-bearing heterocycles toward Taurus Molecular Cloud 1 (TMC-1) using the deep, broadband centimeter-wavelength…
CH3-Terminated Carbon Chains in the GOTHAM Survey of TMC-1: Evidence of Interstellar CH3C7N
Mark A. Siebert, Kin Long Kelvin Lee, Anthony J. Remijan +4
We report a systematic study of all known methyl carbon chains toward TMC-1 using the second data release of the GOTHAM survey, as well as a search for larger species. Using Markov…
Machine Learning of Interstellar Chemical Inventories
Kin Long Kelvin Lee, Jacqueline Patterson, Andrew M. Burkhardt +3
The characterization of interstellar chemical inventories provides valuable insight into the chemical and physical processes in astrophysical sources. The discovery of new interste…
Detection of Two Interstellar Polycyclic Aromatic Hydrocarbons via Spectral Matched Filtering
Brett A. McGuire, Ryan A. Loomis, Andrew M. Burkhardt +12
Ubiquitous unidentified infrared emission bands are seen in many astronomical sources. Although these bands are widely, if not unanimously, attributed to the collective emission fr…
A rotational and vibrational investigation of phenylpropiolonitrile (CHCN)
Zachary Buchanan, Kin Long Kelvin Lee, Olivia Chitarra +3
The evidence for benzonitrile (CHCN}) in the starless cloud core TMC-1 makes high-resolution studies of other aromatic nitriles and their ring-chain derivatives especially…
Ubiquitous Aromatic Carbon Chemistry at the Earliest Stages of Star Formation
Andrew M. Burkhardt, Ryan A. Loomis, Christopher N. Shingledecker +4
Benzonitrile (-CHCN), a polar proxy for benzene (-CH}), has the potential to serve as a highly convenient radio probe for aromatic chemistry, provided this ri…
Interstellar Detection of the Highly Polar Five-Membered Ring Cyanocyclopentadiene
Michael C. McCarthy, Kin Long Kelvin Lee, Ryan A. Loomis +10
Much like six-membered rings, five-membered rings are ubiquitous in organic chemistry, frequently serving as the building blocks for larger molecules, including many of biochemical…
An Investigation of Spectral Line Stacking Techniques and Application to the Detection of HCN
Ryan A. Loomis, Andrew M. Burkhardt, Christopher N. Shingledecker +10
As the inventory of interstellar molecules continues to grow, the gulf between small species, whose individual rotational lines can be observed with radio telescopes, and large one…
Submillimeter spectroscopy and astronomical searches of vinyl mercaptan, CHSH
Marie-Aline Martin-Drumel, Kin Long Kelvin Lee, Arnaud Belloche +8
We have extended the pure rotational investigation of the two isomers syn and anti vinyl mercaptan to the millimeter domain using a frequency-multiplication spectrometer. The speci…
Gas phase detection and rotational spectroscopy of ethynethiol, HCCSH
Kin Long Kelvin Lee, Marine-Aline Martin-Drumel, Valerio Lattanzi +3
We report the gas-phase detection and spectroscopic characterization of ethynethiol (), a metastable isomer of thioketene () using a combination o…
HSCO and DSCO: a multi-technique approach in the laboratory for the spectroscopy of interstellar ions
Valerio Lattanzi, Silvia Spezzano, Jacob C. Laas +5
Protonated molecular species have been proven to be abundant in the interstellar gas. This class of molecules is also pivotal for the determination of important physical parameters…
