We present the fifth portion of an unbiased survey of the Galactic plane, |b| ≤ 2• , for 6668-MHz methanol masers. This section of the survey completes the Galactic longitude range visible to the Parkes radio telescope, incorporating the longitude range 20• -60• . Within this section of the survey we find 265 methanol masers, 64 new to the survey, bringing the total number of methanol masers detected across the full longitude coverage (186• , through 0 • , to 60 • ) to 972 sources.

“…Within high-mass star formation regions, 10.472+0.027 is the most extreme, with features redshifted up to 250 km s −1 from the systemic velocity of the region and a total velocity range of nearly 300 km s −1 (Titmarsh et al 2013). Figure 3.…”

This is the second paper in a series of catalogues of 22-GHz water maser observations towards the 6.7-GHz methanol masers from the Methanol Multibeam (MMB) Survey. In this paper we present our water maser observations made with the Australia Telescope Compact Array towards the masers from the MMB survey between l = 341 • through the Galactic centre to l = 6 • . Of the 204 6.7-GHz methanol masers in this longitude range we found 101 to have associated water maser emission (∼ 50 per cent). We found no difference in the 6.7-GHz methanol maser luminosities of those with and without water masers. In sources where both maser species are observed, the luminosities of the methanol and water masers are weakly correlated. Studying the mid-infrared colours from GLIMPSE we found no differences between the colours of those sources associated with both methanol and water masers and those associated with just methanol. Comparing the column density and dust mass calculated from the 870-µm thermal dust emission observed by ATLASGAL, we found no differences between those sources associated with both water and methanol masers and those with methanol only. Since water masers are collisionally pumped and often show emission further away from their accompanying YSO than the radiatively pumped 6.7-GHz methanol masers, it is likely water masers are not as tightly correlated to the evolution of the parent YSO and so do not trace such a well defined evolutionary state as 6.7-GHz methanol masers.

“…With no velocity shift between the RHCP and LHCP components, a magnetic field non-detection is reported in this work. This source is coincident with a complex high-mass star forming region (Pascucci et al 2004), identified as a 25,000-35,000 M high-mass proto-cluster G010.4722+0.0277 (Ginsburg et al 2012;Urquhart et al 2013) which hosts at least one very young late O, or early B star that may be actively accreting Titmarsh et al (2013).…”

“…The GLIMPSE image shows two separate mid infrared sources with coincident maser emission, one with just the 1720-MHz OH maser and the other with the OH main lines at 1665-and 1667-MHz (MAGMO, Caswell 1998), 6.7-GHz methanol (Green et al 2010) and a water maser (that holds the record for highest velocity emission of any water maser associated with star formation Titmarsh et al 2013).…”

From targeted observations of ground-state OH masers towards 702 Multibeam (MMB) survey 6.7-GHz methanol masers, between Galactic longitudes 186 • through the Galactic centre to 20 • , made as part of the 'MAGMO' project, we present the physical and polarisation properties of the 1720-MHz OH maser transition, including the identification of Zeeman pairs. We present 10 new and 23 previously catalogued 1720-MHz OH maser sources detected towards star formation regions. In addition, we also detected 16 1720-MHz OH masers associated with supernova remnants and two sites of diffuse OH emission. Towards the 33 star formation masers, we identify 44 Zeeman pairs, implying magnetic field strengths ranging from −11.4 to +13.2 mG, and a median magnetic field strength of |B LOS | ∼ 6 mG. With limited statistics, we present the in-situ magnetic field orientation of the masers and the Galactic magnetic field distribution revealed by the 1720-MHz transition. We also examine the association statistics of 1720-MHz OH SFR masers with other ground-state OH masers, excited-state OH masers, class I and class II methanol masers and water masers, and compare maser positions with mid-infrared images of the parent star forming regions. Of the 33 1720-MHz star formation masers, ten are offset from their central exciting sources, and appear to be associated with outflow activity.
