ALMA Detection of Interstellar Methoxymethanol (CH 3 OCH 2 OH)
We report the detection of interstellar methoxymethanol (CH3OCH2OH) in Atacama Large Millimeter/submillimeter Array (ALMA) Bands. 6 and. 7 toward the MM1 core in the high-mass star-forming region NGC… Expand
The complex chemistry of hot cores in Sgr B2(N): influence of cosmic-ray ionization and thermal history
As the number of complex organic molecules (COMs) detected in the interstellar medium increases, it becomes important to place meaningful constraints on the formation pathways of these species. The… Expand
First detection of cyanamide (NH2CN) towards solar-type protostars
Searches for the prebiotically relevant cyanamide (NH 2 CN) towards solar-type protostars have not been reported in the literature. We present here the first detection of this species in the warm gas… Expand
Interstellar detection of the highly polar five-membered ring cyanocyclopentadiene
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… Expand
The ALMA-PILS survey: first detection of methyl isocyanide (CH$_3$NC) in a solar-type protostar.
Methyl isocyanide (CH$_3$NC) is the isocyanide with the largest number of atoms confirmed in the interstellar medium (ISM), but it is not an abundant molecule, having only been detected towards a… Expand
Early Science from GOTHAM: Project Overview, Methods, and the Detection of Interstellar Propargyl Cyanide (HCCCH2CN) in TMC-1
We present an overview of the GOTHAM (GBT Observations of TMC-1: Hunting Aromatic Molecules) Large Program on the Green Bank Telescope. This and a related program were launched to explore the depth… Expand
Interstellar Glycolaldehyde, Methyl Formate, and Acetic Acid I: A Bi-modal Abundance Pattern in Star Forming Regions.
The relative column densities of the structural isomers methyl formate, glycolaldehyde, and acetic acid are derived for a dozen positions towards the massive star-forming regions MM1 and MM2 in the… Expand
Searches for Interstellar HCCSH and H2CCS
A long standing problem in astrochemistry is the inability of many current models to account for missing sulfur content. Many relatively simple species that may be good candidates to sequester sulfur… Expand
First Results of an ALMA Band 10 Spectral Line Survey of NGC 6334I: Detections of Glycolaldehyde (HC(O)CH2OH) and a New Compact Bipolar Outflow in HDO and CS
We present the first results of a pilot program to conduct an ALMA Band 10 spectral line survey of the high-mass star-forming region NGC 6334I. The observations were taken in exceptional weather… Expand
Detection of two interstellar polycyclic aromatic hydrocarbons via spectral matched filtering
Potential in situ gas-phase PAH formation pathways from smaller organic precursor molecules are discussed and two nitrile-group–functionalized PAHs, 1- and 2-cyanonaphthalene, are detected in the interstellar medium. Expand
