Ten years since the NGC 6334I-MM1 accretion outburst: the impact on its environment

G. C. MacLeod, A. Caratti o Garatti, W. A. Baan +11

Ten years on, flaring continues in masers associated with NGC 6334I-MM1. Methanol and hydroxyl masers are nearing quiescent values, but water features remain elevated. Several more…

ALMAGAL VIII. Early phases of triggered star formation in source AG286.07161.8229

C. Mininni, S. Molinari, W. J. Kim +50

Several theoretical and observational studies have shown that new waves of triggered star-formation can be induced by the feedback from newly formed massive protostars, due to the…

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…

Filamentary mass accretion towards the high-mass protobinary system G11.92-0.61 MM2

S. Zhang, C. J. Cyganowski, J. D. Henshaw +5

We present deep, sub-arcsecond (2000 AU) resolution ALMA 0.82 mm observations of the former high-mass prestellar core candidate G11.92-0.61 MM2, recently shown to be an $\sim…

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…
