Science with an ngVLA: Deuteration in starless and prestellar cores
Rachel K. Friesen, Maria T. Beltrán, Paola Caselli +1
In dense starless and protostellar cores, the relative abundance of deuterated species to their non-deuterated counterparts can become orders of magnitude greater than in the local…
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 ALMA-PILS survey: first detection of methyl isocyanide (CHNC) in a solar-type protostar
H. Calcutt, M. R. Fiechter, E. R. Willis +9
Methyl isocyanide (CHNC) is the isocyanide with the largest number of atoms confirmed in the interstellar medium (ISM), but it is not an abundant molecule, having only been det…
The ALMA-PILS survey: Complex nitriles towards IRAS 16293--2422
H. Calcutt, J. K. Jørgensen, H. S. P. Müller +8
Complex organic molecules are readily detected in the inner regions of the gaseous envelopes of forming protostars. In particular, molecules that contain nitrogen are interesting d…
Modeling CO, CO and HO ice abundances in the envelopes of young stellar objects in the Magellanic Clouds
Tyler Pauly, R. T. Garrod
Massive young stellar objects in the Magellanic Clouds show infrared absorption features corresponding to significant abundances of CO, CO and HO ice along the line of sigh…
