Interstellar Glycolaldehyde, Methyl Formate, and Acetic Acid. II. Chemical Modeling of the Bimodal Abundance Pattern in NGC 6334I
Brielle M. Shope, Samer J. El-Abd, Crystal L. Brogan +4
Gas-phase abundance ratios between \ce{C2H4O2} isomers methyl formate (MF), glycolaldehyde (GA), and acetic acid (AA) are typically on the order of 100:10:1 in star-forming regions…
Rotational Spectrum and First Interstellar Detection of 2-Methoxyethanol Using ALMA Observations of NGC 6334I
Zachary T. P. Fried, Samer J. El-Abd, Brian M. Hays +13
We use both chirped-pulse Fourier transform and frequency modulated absorption spectroscopy to study the rotational spectrum of 2-methoxyethanol in several frequency regions rangin…
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…
The Extraordinary Outburst in the Massive Protostellar System NGC6334I-MM1: Strong Increase in Mid-Infrared Continuum Emission
T. R. Hunter, C. L. Brogan, J. M. De Buizer +7
In recent years, dramatic outbursts have been identified toward massive protostars via infrared and millimeter dust continuum and molecular maser emission. The longest lived outbur…
Searches for Interstellar HCCSH and HCCS
Brett A. McGuire, Christopher N. Shingledecker, Eric R. Willis +14
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…
Interstellar Glycolaldehyde, Methyl Formate, and Acetic Acid I: A Bi-modal Abundance Pattern in Star Forming Regions
Samer J. El-Abd, Crystal L. Brogan, Todd R. Hunter +3
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 M…
