(Royal Astronomical Society, 2015)We present a 30–50 GHz survey of Sagittarius B2(N) conducted with the Australia Telescope Compact Array with ∼5–10 arcsec resolution. This work releases the survey data and demonstrates the utility of scripts that perform ...
-
(EDP Sciences, 2015)Context. The formation of high mass stars and clusters occurs in giant molecular clouds. Objects in evolved stages of massive star formation such as protostars, hot molecular cores, and ultracompact HII regions have been ...
-
(IOP Publishing Ltd, 2018)Spectral line surveys reveal rich molecular reservoirs in G331.512-0.103, a compact radio source in the center of an energetic molecular outflow. In this first work, we analyze the physical conditions of the source by means ...
-
(IOP Publishing, 2017)We explore the use of mm-wave emission line ratios to trace molecular gas density when observations integrate over a wide range of volume densities within a single telescope beam. For observations targeting external galaxies, ...
-
(Oxford Univ Press, 2016)Three bright molecular line sources in G333 have recently been shown to exhibit signatures of infall. We describe amolecular line radiative transfer (RT) modelling process which is required to extract the infall signature ...
-
(EDP Sciences, 2017-05)Context. The origin and life-cycle of molecular clouds are still poorly constrained, despite their importance for understanding the evolution of the interstellar medium. Many large-scale surveys of the Galactic plane have ...

(Oxford University Press, 2021)The SEDIGISM (Structure, Excitation and Dynamics of the Inner Galactic InterstellarMedium) survey used the APEX telescope to map 84 deg2 of the Galactic plane between = −60◦ and +31◦ in several molecular transitions, ...
