We have used the Mopra Telescope to search for glycine and the simple chiral molecule propylene oxide in the Sgr B2 (LMH) and Orion KL, in the 3-mm band. We have not detected either species, but have been able to put sensitive upper limits on the abu

General characteristics of methanol (CH3OH) maser emission are summarized. It is shown that methanol maser sources are concentrated in the spiral arms. Most of the methanol maser sources from the Perseus arm are associated with embedded stellar clust

We have used the Australia Telescope Compact Array to conduct a search for the simplest amino acid, glycine (conformers I and II), and the simple chiral molecule propylene oxide at 3-mm in the Sgr B2 LMH. We searched 15 portions of spectrum between 8

We report interferometric observations of nine class II methanol maser candidate lines toward W3(OH). Narrow maser emission spikes at vLSR = -43.1 km s-1 are present in three of the lines: 31-40 A+, 72-63 A+, and 72-63 A-. For all three lines the mas

From a search of more than 80 southern class II methanol maser sites, we report measurements of 22 masers at 107.0 GHz and four at 156.6 GHz, mostly new discoveries. Class II sites, recognized by their strong emission at the 6.6-GHz methanol transiti

We present Australia Telescope Compact Array observations of the 9-GHz, J=1-0, rotational transition of cyanoacetylene (HC3N) arising in the dense molecular clouds associated with the prominent H II region Sgr B2. Images with a synthesized beam of 4.

We investigate the possibility of interstellar masers in transitions of the methanol isotopomers CH3OD, 13CH3OH and CH318OH, and of CH3SH. The model used, in which masers are pumped through the first and second torsionally excited states by IR radiat

The guidance given in BS5930:1981 for rock weathering descriptions at the material scale is considered to be inappropriate for UK practice, and is seldom applied to rock core logging. Practitioners turn to alternative weathering schemes for logging r

We propose that the strong correlation between far-infrared emission and nonthermal radio emission in diverse types of disc galaxy arises because of differences in the chemical evolution of molecular clouds in these galaxies. The chemistry is driven
