We have searched for 12-GHz methanol maser emission from the direction of 173 OH masers in star formation regions and obtained 53 detections, including 19 previously unreported. The observations of these and four other southern methanol masers are pr

58 southern molecular clouds were searched for CH 3 OH absorption at 12.2 GHz, yielding 38 detections. The absorption has a median brightness temperature of 0.22 K, linewidth of 4.2 km/s, and velocity offset of 2.7 km/s from the velocity of the H II

We have mapped the molecular clouds of Sgr B2 in the 110 → 101 ortho-transition of C3H2 at 18.3 GHz, using the 70-m NASA telescope at Tidbinbilla (beamwidth 55 arcsec). Three clouds show absorption against the Sgr B2 continuum emission at radial ve

The 12.2-GHz 20-3-1 transition of CH3OH has been mapped over the continuum source Sgr B2 with a 2-arcmin beam. Strong absorption was observed from three molecular clouds at velocities near 50, 65 and 80 km s-1; the line-to-continuum ratios attained m

Line absorption associated with the 12.2 GHz 20 − 3-1 transition of CH3OH has been mapped towards Sgr A with the Parkes 64-m radio telescope and a 2 arcmin beam. Two concentrations are present, both offset from the continuum peak, with velocities o
