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…
Improved Selection Criteria for HII Regions, based on IRAS Sources
Qing-Zeng Yan, Ye Xu, A. J. Walsh +6
We present new criteria for selecting HII regions from the Infrared Astronomical Satellite (IRAS) Point Source catalogue (PSC), based on an HII region catalogue derived manually fr…
