First detections of methanol maser lines from a rare transition family
Bradley R. Johnson, Simon P. Ellingsen, Shari L. Breen +3
We report the first observations in a rare family of class II methanol maser transitions in both CHOH and CHOH toward three southern high-mass star formation regions…
Variability in extragalactic class I methanol masers: New maser components toward NGC4945 and NGC253
Tiege McCarthy, Simon Ellingsen, Shari Breen +3
We have used the Australia Telescope Compact Array (ATCA) to make new observations of the 36.2-GHz (E) methanol transition toward NGC 4945 and NGC 253. These…
Molecular line search toward the flaring 6.7-GHz methanol masers of G24.33+0.13 and G359.6-0.243: rare maser transitions detected
Tiege McCarthy, Gabor Orosz, Simon Ellingsen +8
We have performed a molecular line search toward the flaring 6.7-GHz masers G24.33+0.13 and G359.62-0.24 using the Australia Telescope Compact Array. We present spectra of the 6.7-…
84-GHz methanol masers, their relationship to 36-GHz methanol masers and their molecular environments
Shari Breen, Yanett Contreras, Joanne Dawson +3
We present observations of the 36- (4_-1 -> 3_0E) and 84-GHz (5_-1 -> 4_0 E) class I methanol maser transitions towards a sample of 94 known class I sites. These observations resul…
Detection of 84-GHz class I methanol maser emission towards NGC 253
Tiege P. McCarthy, Simon P. Ellingsen, Shari L. Breen +2
We have investigated the central region of NGC 253 for the presence of 84.5-GHz (E) methanol emission using the Australia Telescope Compact Array. We present…
Investigations of the Class I methanol masers in NGC 4945
Tiege P. McCarthy, Simon P. Ellingsen, Shari L. Breen +2
We have used the Australia Telescope Compact Array (ATCA) to conduct further observations of the 36.2-GHz (E) methanol transition towards the nearby active ga…
