Abstract
The Australia Telescope Compact Array (ATCA) has been used for high angular resolution imaging of 71 southern class I methanol maser sources quasi-simultaneously at 36 and 44 GHz. The data reveal a high level of morphological and kinematical complexity, and allow us to demonstrate associations, at arcsecond precision, of the class I maser emission with outflows, expanding H II regions, dark clouds, shocks traced by the 4.5-mum emission and 8.0-mum filaments. More than 700 maser component features were found at each of the two methanol transitions, but with only 23 per cent recognizable at both transitions the morphology of class I emission is much better revealed by our survey of both transitions, compared with either one alone. We found that the number of masers falls exponentially with the projected linear distance from the associated class II 6.7-GHz methanol maser. This distribution has a scale of 263±15 mpc, irrespective of the transition. The class I masers associated with OH masers were found to have a tendency to be more spread out, both spatially and in the velocity domain. This is consistent with the expectation that such sources are more evolved. Apart from a small number of high-velocity components (which are largely blueshifted and predominantly seen at 36 GHz), the velocity distribution was found to be Gaussian, peaking near the systemic velocity of the region, which had been estimated as the middle of the velocity interval of the associated class II methanol maser at 6.7 GHz. The mean indicated a small, but significant blueshift asymmetry of -0.57 km s^-1 (uncertainties are 0.06 and 0.07 km s^-1 for the 36- and 44-GHz masers, respectively) with respect to the 6.7-GHz masers. The standard deviation of the velocity distribution was found to be 3.65 � 0.05 and 3.32 � 0.07 km s^-1 for the 36- and 44-GHz masers, respectively. We also suggest a refined rest frequency value of 36 169.238 � 0.011 MHz for the 4_{- 1}-3₀ E methanol transition. eprintid: arXiv:1401.5179	Target sources: single-dish surveys Comments: Simultaneous 36 and 44 GHZ Class I methanol maser survey in southen sky
