We have used the Australia Telescope Compact Array to observe the 36.2-GHz class I methanol maser emission towards NGC 253 and find that it is located at the interface between the nuclear ring and both ends of the galactic bar. This is thought to be the location of the inner Linblad resonance and we suggest that the maser emission in this region is likely due to large-scale cloud–cloud collisions. We have detected the first extragalactic 44.1-GHz class I methanol maser and find that it is… CONTINUE READING
