Distances to southern 6.7-GHz methanol masers through H i self-absorption

Green, J A; McClure-Griffiths, Naomi


We present the kinematic distance ambiguity resolutions of over 400 6.7-GHz methanol masers. Using the data sets of the International Galactic Plane Survey we have extracted Hi spectra towards the sites of methanol maser emission between longitudes 270° and 67° and examined them for evidence of Hi self-absorption. Using well-established criteria we identify 442 resolutions (classified by reliability) with a 1.07:1.11 ratio between near and far kinematic distance assignments. For a sub-sample of...[Show more]
