Unusual shock-excited OH maser emission in a young Planetary Nebula
Hai-Hua Qiao, Andrew J. Walsh, Jose F. Gomez +9
We report on OH maser emission toward G336.644-0.695 (IRAS 16333-4807), which is a H2O maser-emitting Planetary Nebula (PN). We have detected 1612, 1667 and 1720 MHz OH masers at 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…
A search for High Mass Stars Forming in Isolation using CORNISH & ATLASGAL
Chenoa D. Tremblay, Andrew J. Walsh, Steven N. Longmore +2
Theoretical models of high mass star formation lie between two extreme scenarios. At one extreme, all the mass comes from an initially gravitationally-bound core. At the other extr…
A Survey for Hydroxyl in the THOR Pilot Region around W43
Andrew J. Walsh, Henrik Beuther, Simon Bihr +14
We report on observations of the hydroxyl radical (OH) within The H{\sc I}, OH Recombination line survey (THOR) pilot region. The region is bounded approximately between Galactic c…
An ATCA Survey of Sagittarius~B2 at 7~mm: Chemical Complexity Meets Broadband Interferometry
Joanna F. Corby, Paul A. Jones, Maria R. Cunningham +8
We present a 30 - 50 GHz survey of Sagittarius B2(N) conducted with the Australia Telescope Compact Array (ATCA) with 5 - 10 arcsec resolution. This work releases the survey data a…
Radio spectral characteristics of the supernova remnant Puppis A and nearby sources
E. M. Reynoso, A. J. Walsh
This paper presents a new study of the spectral index distribution of the supernova remnant (SNR) Puppis A. The nature of field compact sources is also investigated according to th…
