A Molecular Line Survey toward the Nearby Galaxies NGC 1068, NGC 253, and IC 342 at 3 mm with the Nobeyama 45-m Radio Telescope: Impact of an AGN on 1 kpc Scale Molecular Abundances
Taku Nakajima, Shuro Takano, Kotaro Kohno +2
It is important to investigate the relationships between the power sources and the chemical compositions of galaxies for understanding the scenario of galaxy evolution. We carried…
ALMA Detection of Interstellar Methoxymethanol (CHOCHOH)
Brett A. McGuire, Christopher N. Shingledecker, Eric R. Willis +10
We report the detection of interstellar methoxymethanol (CHOCHOH) in ALMA Bands 6 and 7 toward the MM1 core in the high-mass star-forming region NGC 6334I at ~0.1" - 1" spa…
Detection of HCN and HCN Isotopologues in TMC-1 with the Green Bank Telescope
Andrew M. Burkhardt, Eric Herbst, Sergei V. Kalenskii +3
We report the first interstellar detection of DCN and six C-bearing isotopologues of HCN toward the dark cloud TMC-1 through observations with the Green Bank Telesco…
High Spectral Resolution SOFIA/EXES Observations of C2H2 towards Orion-IRc2
Naseem Rangwala, Sean W. J. Colgan, Romane Le Gal +8
We present high-spectral resolution observations from 12.96 - 13.33 microns towards Orion IRc2 using the mid-infrared spectrograph, EXES, on SOFIA. These observations probe the phy…
The Molecular Chemistry of Diffuse and Translucent Clouds in the Line-of-Sight to Sgr B2
Joanna Corby, Brett McGuire, Eric Herbst +1
The 1-50 GHz GBT PRIMOS data contains ~50 molecular absorption lines observed in diffuse and translucent clouds located in the Galactic Center, Bar, and spiral arms in the line-of-…
A new study of the chemical structure of the Horsehead nebula: the influence of grain-surface chemistry
Romane Le Gal, Eric Herbst, Gwenaelle Dufour +4
A wide variety of molecules have recently been detected in the Horsehead nebula photodissociation region (PDR) suggesting that: (i) gas-phase and grain chemistries should both cont…
