Magnetic Field Alignment Relative to Multiple Tracers in the High-mass Star-forming Region RCW 36
Akanksha Bij, Laura M. Fissel, Lars Bonne +9
We use polarization data from SOFIA HAWC+ to investigate the interplay between magnetic fields and stellar feedback in altering gas dynamics within the high-mass star-forming regio…
A First Look for Molecules between 103 and 133 MHz using the Murchison Widefield Array
Chenoa Tremblay, Natasha Hurley-Walker, Maria Cunningham +4
We detail and present results from a pilot study to assess the feasibility of detecting molecular lines at low radio frequencies. We observed a 400 square degree region centred on…
Follow-up observations toward Planck cold clumps with ground-based radio telescopes
Tie Liu, Yuefang Wu, Diego Mardones +26
The physical and chemical properties of prestellar cores, especially massive ones, are still far from being well understood due to the lack of a large sample. The low dust temperat…
The Millimeter Astronomy Legacy Team 90 GHz (MALT90) Pilot Survey
Jonathan B. Foster, James M. Jackson, Elizabeth Barris +11
We describe a pilot survey conducted with the Mopra 22-m radio telescope in preparation for the Millimeter Astronomy Legacy Team Survey at 90 GHz (MALT90). We identified 182 candid…
A Molecular Line Survey around Orion at Low Frequencies with the MWA
Chenoa D. Tremblay, Paul A. Jones, Maria Cunningham +3
The low-frequency sky may reveal some of the secrets yet to be discovered and until recently, molecules had never been detected within interstellar clouds at frequencies below 700M…
Low-Frequency Carbon Recombination Lines in the Orion Molecular Cloud Complex
Chenoa D. Tremblay, Christopher H. Jordan, Maria Cunningham +2
We detail tentative detections of low-frequency carbon radio recombination lines from within the Orion molecular cloud complex observed at 99-129 MHz. These tentative detections in…
Diatomic rovibronic transitions as potential probes for proton-to-electron mass ratio across cosmological time
Anna-Maree Syme, Adam Mousley, Maria Cunningham +1
Astrophysical molecular spectroscopy is an important method of searching for new physics through probing the variation of the proton-to-electron mass ratio, , with existing con…
Relative Alignment Between the Magnetic Field and Molecular Gas Structure in the Vela C Giant Molecular Cloud using Low and High Density Tracers
Laura M. Fissel, Peter A. R. Ade, Francesco E. Angilè +37
We compare the magnetic field orientation for the young giant molecular cloud Vela C inferred from 500-m polarization maps made with the BLASTPol balloon-borne polarimeter to t…
High-mass star-forming cloud G0.38+0.04 in the Galactic Center Dust Ridge contains H2CO and SiO masers
Adam Ginsburg, Andrew Walsh, Christian Henkel +15
We have discovered a new HCO (formaldehyde) 4.82966 GHz maser in Galactic Center Cloud C, G0.38+0.04. At the time of acceptance, this is the eighth region con…
The Nature of the Stingray Nebula from Radio Observations
Lisa Harvey-Smith, Jennifer A Hardwick, Orsola De Marco +5
We have analysed the full suite of Australia Telescope Compact Array data for the Stingray planetary nebula. Data were taken in the 4- to 23-GHz range of radio frequencies between…
A Spitzer Space Telescope survey of massive young stellar objects in the G333.2-0.4 giant molecular cloud
Janet P. Simpson, Angela S. Cotera, Michael G. Burton +3
The G333 giant molecular cloud contains a few star clusters and H II regions, plus a number of condensations currently forming stars. We have mapped 13 of these sources with the ap…
The Three-mm Ultimate Mopra Milky Way Survey. II. Cloud and Star Formation Near the Filamentary Ministarburst RCW 106
Hans Nguyen, Quang Nguyen Luong, Peter G. Martin +9
We report here a study of gas, dust and star formation rates (SFRs) in the molecular cloud complexes (MCCs) surrounding the giant H region RCW106 using…
ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): Detection of extremely high density compact structure of prestellar cores and multiple substructures within
Dipen Sahu, Sheng-Yuan Liu, Tie Liu +38
Prestellar cores are self-gravitating dense and cold structures within molecular clouds where future stars are born. They are expected, at the stage of transitioning to the protost…
