A relationship between dust-reprocessed light from recent star formation and the amount of star-forming gas in a galaxy produces a correlation between Wide-field Infrared Survey...

In order to search for shocks in the very early stage of star formation, we performed single-point surveys of SiO J=1-0, 2-1, and 3-2 lines and the H_2_CO 2_12_-1_11_ line...

We present the results of a blind search for intervening HI 21cm absorption towards 260 radio sources in the redshift range 0<z<2.74 with the Green Bank Telescope. The...

We present an analysis of morphological, kinematic, and spectral asymmetries in observations of atomic neutral hydrogen (HI) gas from the Local Volume HI Survey (LVHIS), the VLA...

Methanol masers at 6.7GHz are the brightest of class II methanol masers and have been found exclusively towards massive star-forming regions. These masers can thus be used as a...

We have constructed the largest sample of dust-associated class II 6.7GHz methanol masers yet obtained. New measurements from the Methanol Multibeam (MMB) survey were combined...

HI stacking has proven to be a highly effective tool to statistically analyse average HI properties for samples of galaxies which may or may not be directly detected. With the...

We present maps of the ionized gas flux distributions, excitation, star formation rate (SFR), surface mass density {Sigma}H+, and obtain total values of SFR and ionized gas...

Red supergiant stars are surrounded by a gaseous and dusty circumstellar environment created by their mass loss which spreads heavy elements into the interstellar medium. The...

We report results of 6.7GHz methanol maser monitoring of 139 star-forming sites with the Torun 32-m radio telescope from 2009 June to 2013 February. The targets were observed at...

We detail interferometric observations of 44GHz class I methanol masers detected by MALT-45 (a 7mm unbiased auto-correlated spectral-line Galactic-plane survey) using the...

The H_2_O Southern Galactic Plane Survey (HOPS) has mapped 100deg^2^ of the Galactic plane for water masers and thermal molecular line emission using the 22m Mopra telescope. We...

The star-forming reservoir in the distant Universe can be detected through HI 21-cm absorption arising from either cool gas associated with a radio source or from within a...

In this work, we aim to characterize high-mass clumps with infall motions. We selected 327 clumps from the Millimetre Astronomy Legacy Team 90-GHz survey, and identified 100...

We present the results of the first complete unbiased survey of the Galactic plane for 6035-MHz excited-state hydroxyl (ex-OH) masers undertaken as part of the methanol...

We present results of a blind 21cm HI-line imaging survey of a galaxy overdensity located behind the Milky Way at l, b ~= 160{deg}, 0.5{deg}. The overdensity corresponds to a...

OH megamasers (OHMs) are rare, luminous molecular masers that are typically observed in (ultra) luminous infrared galaxies and serve as markers of major galaxy mergers. In blind...

Experiments that pursue detection of signals from the Epoch of Reionization (EoR) are relying on spectral smoothness of source spectra at low frequencies. This article...

We present a 30-50GHz survey of Sagittarius B2(N) conducted with the Australia Telescope Compact Array (ATCA) with 5 - 10 arcsec resolution. We analyze the spectra towards three...

We present polarimetric maser observations with the Australia Telescope Compact Array of excited-state hydroxyl (OH) masers. We observed 30 fields of OH masers in full Stokes...
