Astronomical Detection of the Interstellar Anion C10H- towards TMC-1 from the GOTHAM Large Program on the GBT
Anthony Remijan, Haley N. Scolati, Andrew M. Burkhardt +13
Using data from the GOTHAM (GBT Observations of TMC-1: Hunting for Aromatic Molecules) survey, we report the first astronomical detection of the C10H- anion. The astronomical obser…
Discovery of Interstellar 2-Cyanoindene (2-CHCN) in GOTHAM Observations of TMC-1
Madelyn L. Sita, P. Bryan Changala, Ci Xue +12
We present laboratory rotational spectroscopy of five isomers of cyanoindene (2-, 4-, 5-, 6-, and 7-cyanoindene) using a cavity Fourier-transform microwave spectrometer operating b…
Discovery of the Pure Polycyclic Aromatic Hydrocarbon Indene (-CH) with GOTHAM Observations of TMC-1
Andrew M. Burkhardt, Kin Long Kelvin Lee, P. Bryan Changala +8
Polycyclic Aromatic Hydrocarbons (PAHs) have long been invoked in the study of interstellar and protostellar sources, but the unambiguous identification of any individual PAH has p…
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…
Discovery of Interstellar trans-cyanovinylacetylene (HCCCH=CHCN) and vinylcyanoacetylene (HC=CHCN) in GOTHAM Observations of TMC-1
Kin Long Kelvin Lee, Ryan A. Loomis, Andrew M. Burkhardt +8
We report the discovery of two unsaturated organic species, trans-(E)-cyanovinylacetylene and vinylcyanoacetylene, using the second data release of the GOTHAM deep survey towards T…
A New Method for Simulating Photoprocesses in Astrochemical Models
Ella Mullikin, Hannah Anderson, Natalie O'Hern +8
We propose a new model for treating solid-phase photoprocesses in interstellar ice analogues. In this approach, photoionization and photoexcitation are included in more detail, and…
