  • Astronomical Detection of the Interstellar Anion C<sub>10</sub>H<sup>-</sup> toward TMC-1 from the GOTHAM Large Program on the Green Bank Telescope 
    Remijan, Anthony; Scolati, Haley N.; Burkhardt, Andrew M.; Changala, P. Bryan; Charnley, Steven B.; Cooke, Ilsa R.; Cordiner, Martin A.; Gupta, Harshal; Herbst, Eric; Kelvin Lee, Kin Long; Loomis, Ryan A.; Shingledecker, Christopher N.; Siebert, Mark A.; Xue, Ci; McCarthy, Michael C.; McGuire, Brett A. (2023)
    Using data from the Green Bank Telescope (GBT) Observations of TMC-1: Hunting for Aromatic Molecules (GOTHAM) survey, we report the first astronomical detection of the C<sub>10</sub>H<sup>-</sup> anion. The astronomical ...
  • Detection of two interstellar polycyclic aromatic hydrocarbons via spectral matched filtering 
    McGuire, Brett A.; Loomis, Ryan A.; Burkhardt, Andrew M.; Lee, Kin Long Kelvin; Shingledecker, Christopher N.; Charnley, Steven B.; Cooke, Ilsa R.; Cordiner, Martin A.; Herbst, Eric; Kalenskii, Sergei; Siebert, Mark A.; Willis, Eric R.; Xue, Ci; Remijan, Anthony J.; McCarthy, Michael C. (2021)
    Unidentified infrared emission bands are ubiquitous in many astronomical sources. These bands are widely, if not unanimously, attributed to collective emissions from polycyclic aromatic hydrocarbon (PAH) molecules, yet no ...
  • Discovery of Interstellar trans-cyanovinylacetylene (HC = CCH = CHC = N) and vinylcyanoacetylene (H<SUB>2</SUB>C = CHC<SUB>3</SUB>N) in GOTHAM Observations of TMC-1 
    Lee, Kin Long Kelvin; Loomis, Ryan A.; Burkhardt, Andrew M.; Cooke, Ilsa R.; Xue, Ci; Siebert, Mark A.; Shingledecker, Christopher N.; Remijan, Anthony; Charnley, Steven B.; McCarthy, Michael C.; McGuire, Brett A. (2021)
    We report the discovery of two unsaturated organic species, trans-(E)-cyanovinylacetylene and vinylcyanoacetylene, using the second data release of the GOTHAM deep survey toward TMC-1 with the 100 m Green Bank Telescope. ...
  • Interstellar Detection of 2-cyanocyclopentadiene, C<SUB>5</SUB>H<SUB>5</SUB>CN, a Second Five-membered Ring toward TMC-1 
    Lee, Kin Long Kelvin; Changala, P. Bryan; Loomis, Ryan A.; Burkhardt, Andrew M.; Xue, Ci; Cordiner, Martin A.; Charnley, Steven B.; McCarthy, Michael C.; McGuire, Brett A. (2021)
    Using radio observations with the Green Bank Telescope, evidence has now been found for a second five-membered ring in the dense cloud Taurus Molecular Cloud-1 (TMC-1). Based on additional observations of an ongoing, ...
  • Interstellar detection of the highly polar five-membered ring cyanocyclopentadiene 
    McCarthy, Michael C.; Lee, Kin Long Kelvin; Loomis, Ryan A.; Burkhardt, Andrew M.; Shingledecker, Christopher N.; Charnley, Steven B.; Cordiner, Martin A.; Herbst, Eric; Kalenskii, Sergei; Willis, Eric R.; Xue, Ci; Remijan, Anthony J.; McGuire, Brett A. (2021)
    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 importance. From a combination of laboratory ...
  • An investigation of spectral line stacking techniques and application to the detection of HC<SUB>11</SUB>N 
    Loomis, Ryan A.; Burkhardt, Andrew M.; Shingledecker, Christopher N.; Charnley, Steven B.; Cordiner, Martin A.; Herbst, Eric; Kalenskii, Sergei; Lee, Kin Long Kelvin; Willis, Eric R.; Xue, Ci; Remijan, Anthony J.; McCarthy, Michael C.; McGuire, Brett A. (2021)
    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 ones, such as polycyclic aromatic hydrocarbons ...
  • Rapidly Varying Anisotropic Methanol (CH<SUB>3</SUB>OH) Production in the Inner Coma of Comet 46P/Wirtanen as Revealed by the ALMA Atacama Compact Array 
    Roth, Nathan X.; Milam, Stefanie N.; Cordiner, Martin A.; Bockelée-Morvan, Dominique; DiSanti, Michael A.; Boissier, Jérémie; Biver, Nicolas; Crovisier, Jacques; Russo, Neil Dello; Bonev, Boncho P.; Qi, Chunhua; Remijan, Anthony J.; Charnley, Steven B.; Gibb, Erika L.; Val-Borro, Miguel de; Jehin, Emmanuël (2021)
    We report the detection of CH<SUB>3</SUB>OH emission in comet 46P/Wirtanen on UT 2018 December 8 and 9 using the Atacama Compact Array (ACA), part of the Atacama Large Millimeter/Submillimeter Array (ALMA). These interferometric ...
