Interferometric and single-dish observations of 44, 84 and 95 GHz Class I methanol masers
Carolina B. Rodríguez-Garza, Stanley E. Kurtz, Arturo I. Gómez-Ruiz +3
We present observations of massive star-forming regions selected from the IRAS Point Source Catalog. The observations were made with the Very Large Array and the Large Millimeter T…
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…
Analytical Methods for Measuring the Parameters of Interstellar Gas Using the Data of Methanol Observations
S. V. Kalenskii, S. Kurtz
We analyze methanol excitation in the absence of external radiation and consider LTE methods for probing interstellar gas. We show that rotation diagrams correctly estimate the gas…
A catalog of 44 GHz methanol masers in massive star-forming regions. IV. The high-mass protostellar object sample
Carolina B. Rodríguez-Garza, Stanley E. Kurtz, Arturo I. Gómez-Ruiz +3
We present a survey of 56 massive star-forming regions in the 44 GHz methanol maser transition made with the Karl G. Jansky Very Large Array (VLA); 24 of the 56 fields showed maser…
Possible detection of interstellar benzonitrile
S. V. Kalenskii
The simplest cyanobenzene, benzonitrile (c-C6H5CN) have been possibly detected toward the cyanopolyyne peak in TMC-1. We used the results of the 8.8 -- 50 GHz spectral survey of TM…
Detection of Interstellar HCO in TMC-1 with the Green Bank Telescope
Brett A. McGuire, Andrew M. Burkhardt, Christopher N. Shingledecker +4
We report the detection of the carbon-chain radical HCO for the first time in the interstellar medium toward the dark cloud TMC-1 using the 100 m Green Bank Telescope. We obser…
