Mapping physical parameters in Orion KL at high spatial resolution
Olivia H. Wilkins, P. Brandon Carroll, Geoffrey A. Blake
The Orion Kleinmann-Low nebula (Orion KL) is notoriously complex and exhibits a range of physical and chemical components. We conducted high angular resolution (sub-arcsecond) obse…
A Search for Light Hydrides in the Envelopes of Evolved Stars
Mark A. Siebert, Ignacio Simon, Christopher N. Shingledecker +7
We report a search for the diatomic hydrides SiH, PH, and FeH along the line of sight toward the chemically rich circumstellar envelopes of IRC+10216 and VY Canis Majoris. These mo…
Science with an ngVLA: Prebiotic Molecules
Brett A. McGuire, P. Brandon Carroll, Robin T. Garrod
Extraterrestrial amino acids, the chemical building blocks of the biopolymers that comprise life as we know it on Earth are present in meteoritic samples. More recently, glycine (N…
First Results of an ALMA Band 10 Spectral Line Survey of NGC 6334I: Detections of Glycolaldehyde (HC(O)CHOH) and a New Compact Bipolar Outflow in HDO and CS
Brett A. McGuire, Crystal L. Brogan, Todd R. Hunter +9
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 excep…
The Final Integrations of the Caltech Submillimeter Observatory
Brett A. McGuire, P. Brandon Carroll
We present the final observations of the Caltech Submillimeter Observatory, taken toward Orion KL, prior to its decommissioning after nearly three decades of operation.
Non-Detection of HCN toward TMC-1: Constraining the Chemistry of Large Carbon-Chain Molecules
Ryan A. Loomis, Christopher N. Shingledecker, Glen Langston +8
Bell et al. (1997) reported the first detection of the cyanopolyyne HCN toward the cold dark cloud TMC-1; no subsequent detections have been reported toward any source. Addi…
Discovery of the Interstellar Chiral Molecule Propylene Oxide (CHCHCHO)
Brett A. McGuire, P. Brandon Carroll, Ryan A. Loomis +4
Life on Earth relies on chiral molecules, that is, species not superimposable on their mirror images. This manifests itself in the selection of a single molecular handedness, or ho…
CSO and CARMA Observations of L1157. II. Chemical Complexity in the Shocked Outflow
Andrew M. Burkhardt, Niklaus M. Dollhopf, Joanna F. Corby +8
L1157, a molecular dark cloud with an embedded Class 0 protostar possessing a bipolar outflow, is an excellent source for studying shock chemistry, including grain-surface chemistr…
CSO and CARMA Observations of L1157. I. A Deep Search for Hydroxylamine (NHOH)
Brett A. McGuire, P. Brandon Carroll, Niklaus M. Dollhopf +7
A deep search for the potential glycine precursor hydroxylamine (NHOH) using the Caltech Submillimeter Observatory (CSO) at mm and the Combined Array for Research in M…
The Search for a Complex Molecule in a Selected Hot Core Region: A Rigorous Attempt to Confirm trans-Ethyl Methyl Ether toward W51 e1/e2
P. Brandon Carroll, Brett A. McGuire, Geoffrey A. Blake +3
An extensive search has been conducted to confirm transitions of \textit{trans}-ethyl methyl ether (tEME, CHOCH), toward the high mass star forming region W51 e1/e2 usi…
A CSO Search for -CH: Detection in the Orion Bar PDR
Brett A. McGuire, P. Brandon Carroll, James L. Sanders +3
The results of a Caltech Submillimeter Observatory (CSO) search for -CH, first detected by Pety et al. (2012) in observations toward the Horsehead photodissociation regi…
An observational investigation of the identity of B11244 (-CH/CH)
Brett A. McGuire, P. Brandon Carroll, Pierre Gratier +6
Pety et al. (2012) have reported the detection of eight transitions of a closed-shell, linear molecule (B11244) in observations toward the Horsehead PDR, which they attribute to th…
A Search for l-C3H+ and l-C3H in Sgr B2(N), Sgr B2(OH), and the Dark Cloud TMC-1
Brett A. McGuire, P. Brandon Carroll, Ryan A. Loomis +5
Pety et al. (2012) recently reported the detection of several transitions of an unknown carrier in the Horsehead PDR and attribute them to l-C3H+. Here, we have tested the predicti…
A CSO Broadband Spectral Line Survey of Sgr B2(N)-LMH from 260 - 286 GHz
Brett A. McGuire, P. Brandon Carroll, Anthony J. Remijan
Presented here are the results of a broadband spectral line survey of the Sgr B2(N) - LMH region from 260 - 286 GHz using the Caltech Submillimeter Observatory. The data were taken…
